+**Multi-mode apps with merged defaults**:
+
+Apps with multiple operating modes can define separate defaults dictionaries and merge them based on the current mode. The camera app demonstrates this pattern with normal and QR scanning modes:
+
+```python
+# Define defaults in your settings class
+class CameraSettingsActivity:
+    # Common defaults shared by all modes
+    COMMON_DEFAULTS = {
+        "brightness": 1,
+        "contrast": 0,
+        "saturation": 0,
+        "hmirror": False,
+        "vflip": True,

+
+**Benefits of this pattern**:
+- Single source of truth for all 30 camera settings defaults
+- Mode-specific config files (`config.json`, `config_scanqr.json`)
+- ~90% reduction in config file size (only non-default values stored)
+- Eliminates hardcoded defaults throughout the codebase
+- No need to pass defaults to every `get_int()`/`get_bool()` call
+- Self-documenting code with clear defaults dictionaries
+
+**Note**: Use `dict.update()` instead of `{**dict1, **dict2}` for MicroPython compatibility (dictionary unpacking syntax not supported).
+
 **Intent system**: Launch activities and pass data

+### Webcam Module (Desktop Only)
+
+The `c_mpos/src/webcam.c` module provides webcam support for desktop builds using the V4L2 API.
+
+**Resolution Adaptation**:
+- Automatically queries supported YUYV resolutions from the webcam using V4L2 API
+- Supports all 23 ESP32 camera resolutions via intelligent cropping/padding
+- **Center cropping**: When requesting smaller than available (e.g., 240x240 from 320x240)
+- **Black border padding**: When requesting larger than maximum supported
+- Always returns exactly the requested dimensions for API consistency
+
+**Behavior**:
+- On first init, queries device for supported resolutions using `VIDIOC_ENUM_FRAMESIZES`
+- Selects smallest capture resolution ≥ requested dimensions (minimizes memory/bandwidth)
+- Converts YUYV to RGB565 (color) or grayscale during capture
+- Caches supported resolutions to avoid re-querying device
+
+**Examples**:
+
+*Cropping (common case)*:
+- Request: 240x240 (not natively supported)
+- Capture: 320x240 (nearest supported YUYV resolution)
+- Process: Extract center 240x240 region
+- Result: 240x240 frame with centered content
+
+*Padding (rare case)*:
+- Request: 1920x1080
+- Capture: 1280x720 (webcam maximum)
+- Process: Center 1280x720 content in 1920x1080 buffer with black borders
+- Result: 1920x1080 frame (API contract maintained)
+
+**Performance**:
+- Exact matches use fast path (no cropping overhead)
+- Cropped resolutions add ~5-10% CPU overhead
+- Padded resolutions add ~3-5% CPU overhead (memset + center placement)
+- V4L2 buffers sized for capture resolution, conversion buffers sized for output
+
+**Implementation Details**:
+- YUYV format: 2 pixels per macropixel (4 bytes: Y0 U Y1 V)
+- Crop offsets must be even for proper YUYV alignment
+- Center crop formula: `offset = (capture_dim - output_dim) / 2`, then align to even
+- Supported resolutions cached in `supported_resolutions_t` structure
+- Separate tracking of `capture_width/height` (from V4L2) vs `output_width/height` (user requested)
+
+**File Location**: `c_mpos/src/webcam.c` (C extension module)

+## Audio System (AudioFlinger)
+
+MicroPythonOS provides a centralized audio service called **AudioFlinger** (Android-inspired) that manages audio playback across different hardware outputs.
+
+### Supported Audio Devices
+
+- **I2S**: Digital audio output for WAV file playback (Fri3d badge, Waveshare board)
+- **Buzzer**: PWM-based tone/ringtone playback (Fri3d badge only)
+- **Both**: Simultaneous I2S and buzzer support
+- **Null**: No audio (desktop/Linux)
+
+### Basic Usage
+
+**Playing WAV files**:
+```python
+import mpos.audio.audioflinger as AudioFlinger
+
+# Play music file
+success = AudioFlinger.play_wav(
+    "M:/sdcard/music/song.wav",
+    stream_type=AudioFlinger.STREAM_MUSIC,
+    volume=80,
+    on_complete=lambda msg: print(msg)
+)
+
+if not success:
+    print("Audio playback rejected (higher priority stream active)")
+```
+
+**Playing RTTTL ringtones**:
+```python
+# Play notification sound via buzzer
+rtttl = "Nokia:d=4,o=5,b=225:8e6,8d6,8f#,8g#,8c#6,8b,d,8p,8b,8a,8c#,8e"
+AudioFlinger.play_rtttl(
+    rtttl,
+    stream_type=AudioFlinger.STREAM_NOTIFICATION
+)
+```
+
+**Volume control**:
+```python
+AudioFlinger.set_volume(70)  # 0-100
+volume = AudioFlinger.get_volume()
+```
+
+**Stopping playback**:
+```python
+AudioFlinger.stop()
+```
+
+### Audio Focus Priority
+
+AudioFlinger implements priority-based audio focus (Android-inspired):
+- **STREAM_ALARM** (priority 2): Highest priority
+- **STREAM_NOTIFICATION** (priority 1): Medium priority
+- **STREAM_MUSIC** (priority 0): Lowest priority
+
+Higher priority streams automatically interrupt lower priority streams. Equal or lower priority streams are rejected while a stream is playing.
+
+### Hardware Support Matrix
+
+| Board | I2S | Buzzer | LEDs |
+|-------|-----|--------|------|
+| Fri3d 2024 Badge | ✓ (GPIO 2, 47, 16) | ✓ (GPIO 46) | ✓ (5 RGB, GPIO 12) |
+| Waveshare ESP32-S3 | ✓ (GPIO 2, 47, 16) | ✗ | ✗ |
+| Linux/macOS | ✗ | ✗ | ✗ |
+
+### Configuration
+
+Audio device preference is configured in Settings app under "Advanced Settings":
+- **Auto-detect**: Use available hardware (default)
+- **I2S (Digital Audio)**: Digital audio only
+- **Buzzer (PWM Tones)**: Tones/ringtones only
+- **Both I2S and Buzzer**: Use both devices
+- **Disabled**: No audio
+
+**Note**: Changing the audio device requires a restart to take effect.
+
+### Implementation Details
+
+- **Location**: `lib/mpos/audio/audioflinger.py`
+- **Pattern**: Module-level singleton (similar to `battery_voltage.py`)
+- **Thread-safe**: Uses locks for concurrent access
+- **Background playback**: Runs in separate thread
+- **WAV support**: 8/16/24/32-bit PCM, mono/stereo, auto-upsampling to ≥22050 Hz
+- **RTTTL parser**: Full Ring Tone Text Transfer Language support with exponential volume curve
+
+## LED Control (LightsManager)
+
+MicroPythonOS provides a simple LED control service for NeoPixel RGB LEDs (Fri3d badge only).
+
+### Basic Usage
+
+**Check availability**:
+```python
+import mpos.lights as LightsManager
+
+if LightsManager.is_available():
+    print(f"LEDs available: {LightsManager.get_led_count()}")
+```
+
+**Control individual LEDs**:
+```python
+# Set LED 0 to red (buffered)
+LightsManager.set_led(0, 255, 0, 0)
+
+# Set LED 1 to green
+LightsManager.set_led(1, 0, 255, 0)
+
+# Update hardware
+LightsManager.write()
+```
+
+**Control all LEDs**:
+```python
+# Set all LEDs to blue
+LightsManager.set_all(0, 0, 255)
+LightsManager.write()
+
+# Clear all LEDs (black)
+LightsManager.clear()
+LightsManager.write()
+```
+
+**Notification colors**:
+```python
+# Convenience method for common colors
+LightsManager.set_notification_color("red")
+LightsManager.set_notification_color("green")
+# Available: red, green, blue, yellow, orange, purple, white
+```
+
+### Custom Animations
+
+LightsManager provides one-shot control only (no built-in animations). Apps implement custom animations using the `update_frame()` pattern:
+
+```python
+import time
+import mpos.lights as LightsManager
+
+def blink_pattern():
+    for _ in range(5):
+        LightsManager.set_all(255, 0, 0)
+        LightsManager.write()
+        time.sleep_ms(200)
+
+        LightsManager.clear()
+        LightsManager.write()
+        time.sleep_ms(200)
+
+def rainbow_cycle():
+    colors = [
+        (255, 0, 0),    # Red
+        (255, 128, 0),  # Orange
+        (255, 255, 0),  # Yellow
+        (0, 255, 0),    # Green
+        (0, 0, 255),    # Blue
+    ]
+
+    for i, color in enumerate(colors):
+        LightsManager.set_led(i, *color)
+
+    LightsManager.write()
+```
+
+**For frame-based LED animations**, use the TaskHandler event system:
+
+```python
+import mpos.ui
+import time
+
+class LEDAnimationActivity(Activity):
+    last_time = 0
+    led_index = 0
+
+    def onResume(self, screen):
+        self.last_time = time.ticks_ms()
+        mpos.ui.task_handler.add_event_cb(self.update_frame, 1)
+
+    def onPause(self, screen):

+### Implementation Details
+
+- **Location**: `lib/mpos/lights.py`
+- **Pattern**: Module-level singleton (similar to `battery_voltage.py`)
+- **Hardware**: 5 NeoPixel RGB LEDs on GPIO 12 (Fri3d badge)
+- **Buffered**: LED colors are buffered until `write()` is called
+- **Thread-safe**: No locking (single-threaded usage recommended)
+- **Desktop**: Functions return `False` (no-op) on desktop builds
+
 ## Animations and Game Loops
 
 MicroPythonOS supports frame-based animations and game loops using the TaskHandler event system. This pattern is used for games, particle effects, and smooth animations.

Subject: [PATCH 071/859] AudioFlinger: re-add viper optimizations

These make a notable difference when playing audio on ESP32.

Without them, each UI action causes a stutter, so it's not fun to listen
to audio while doing anything on the device. With them, most UI actions don't
cause a stutter. Long maxed out CPU runs and storage access still do, though.

+## Sensor System (SensorManager)
+
+MicroPythonOS provides a unified sensor framework called **SensorManager** (Android-inspired) that provides easy access to motion sensors (accelerometer, gyroscope) and temperature sensors across different hardware platforms.
+
+### Supported Sensors
+
+**IMU Sensors:**
+- **QMI8658** (Waveshare ESP32-S3): Accelerometer, Gyroscope, Temperature
+- **WSEN_ISDS** (Fri3d Camp 2024 Badge): Accelerometer, Gyroscope
+
+**Temperature Sensors:**
+- **ESP32 MCU Temperature**: Internal SoC temperature sensor
+- **IMU Chip Temperature**: QMI8658 chip temperature
+
+### Basic Usage
+
+**Check availability and read sensors**:
+```python
+import mpos.sensor_manager as SensorManager
+
+# Check if sensors are available
+if SensorManager.is_available():
+    # Get sensors
+    accel = SensorManager.get_default_sensor(SensorManager.TYPE_ACCELEROMETER)
+    gyro = SensorManager.get_default_sensor(SensorManager.TYPE_GYROSCOPE)
+    temp = SensorManager.get_default_sensor(SensorManager.TYPE_SOC_TEMPERATURE)
+
+    # Read data (returns standard SI units)
+    accel_data = SensorManager.read_sensor(accel)  # Returns (x, y, z) in m/s²
+    gyro_data = SensorManager.read_sensor(gyro)    # Returns (x, y, z) in deg/s
+    temperature = SensorManager.read_sensor(temp)  # Returns °C
+
+    if accel_data:
+        ax, ay, az = accel_data
+        print(f"Acceleration: {ax:.2f}, {ay:.2f}, {az:.2f} m/s²")
+```
+
+### Sensor Types
+
+```python
+# Motion sensors
+SensorManager.TYPE_ACCELEROMETER    # m/s² (meters per second squared)
+SensorManager.TYPE_GYROSCOPE        # deg/s (degrees per second)
+
+# Temperature sensors
+SensorManager.TYPE_SOC_TEMPERATURE  # °C (MCU internal temperature)
+SensorManager.TYPE_IMU_TEMPERATURE  # °C (IMU chip temperature)
+```
+
+### Tilt-Controlled Game Example
+
+```python
+from mpos.app.activity import Activity
+import mpos.sensor_manager as SensorManager
+import mpos.ui
+import time
+
+class TiltBallActivity(Activity):
+    def onCreate(self):
+        self.screen = lv.obj()
+
+        # Get accelerometer
+        self.accel = SensorManager.get_default_sensor(SensorManager.TYPE_ACCELEROMETER)
+
+        # Create ball UI
+        self.ball = lv.obj(self.screen)
+        self.ball.set_size(20, 20)
+        self.ball.set_style_radius(10, 0)
+
+        # Physics state
+        self.ball_x = 160.0
+        self.ball_y = 120.0
+        self.ball_vx = 0.0
+        self.ball_vy = 0.0
+        self.last_time = time.ticks_ms()
+
+        self.setContentView(self.screen)
+
+    def onResume(self, screen):
+        self.last_time = time.ticks_ms()
+        mpos.ui.task_handler.add_event_cb(self.update_physics, 1)
+
+    def onPause(self, screen):
+        mpos.ui.task_handler.remove_event_cb(self.update_physics)
+
+    def update_physics(self, a, b):
+        current_time = time.ticks_ms()
+        delta_time = time.ticks_diff(current_time, self.last_time) / 1000.0
+        self.last_time = current_time
+
+        # Read accelerometer
+        accel = SensorManager.read_sensor(self.accel)
+        if accel:
+            ax, ay, az = accel
+
+            # Apply acceleration to velocity
+            self.ball_vx += (ax * 5.0) * delta_time
+            self.ball_vy -= (ay * 5.0) * delta_time  # Flip Y
+
+            # Update position
+            self.ball_x += self.ball_vx
+            self.ball_y += self.ball_vy
+
+            # Update ball position
+            self.ball.set_pos(int(self.ball_x), int(self.ball_y))
+```
+
+### Calibration
+
+Calibration removes sensor drift and improves accuracy. The device must be **stationary** during calibration.
+
+```python
+# Calibrate accelerometer and gyroscope
+accel = SensorManager.get_default_sensor(SensorManager.TYPE_ACCELEROMETER)
+gyro = SensorManager.get_default_sensor(SensorManager.TYPE_GYROSCOPE)
+
+# Calibrate (100 samples, device must be flat and still)
+accel_offsets = SensorManager.calibrate_sensor(accel, samples=100)
+gyro_offsets = SensorManager.calibrate_sensor(gyro, samples=100)
+
+# Calibration is automatically saved to SharedPreferences
+# and loaded on next boot
+```
+
+### Performance Recommendations
+
+**Polling rate recommendations:**
+- **Games**: 20-30 Hz (responsive but not excessive)
+- **UI feedback**: 10-15 Hz (smooth for tilt UI)
+- **Background monitoring**: 1-5 Hz (screen rotation, pedometer)
+
+```python
+# ❌ BAD: Poll every frame (60 Hz)
+def update_frame(self, a, b):
+    accel = SensorManager.read_sensor(self.accel)  # Too frequent!
+
+# ✅ GOOD: Poll every other frame (30 Hz)
+def update_frame(self, a, b):
+    self.frame_count += 1
+    if self.frame_count % 2 == 0:
+        accel = SensorManager.read_sensor(self.accel)
+```
+
+### Hardware Support Matrix
+
+| Platform | Accelerometer | Gyroscope | IMU Temp | MCU Temp |
+|----------|---------------|-----------|----------|----------|
+| Waveshare ESP32-S3 | ✅ QMI8658 | ✅ QMI8658 | ✅ QMI8658 | ✅ ESP32 |
+| Fri3d 2024 Badge | ✅ WSEN_ISDS | ✅ WSEN_ISDS | ❌ | ✅ ESP32 |
+| Desktop/Linux | ❌ | ❌ | ❌ | ❌ |
+
+### Implementation Details
+
+- **Location**: `lib/mpos/sensor_manager.py`
+- **Pattern**: Module-level singleton (similar to `battery_voltage.py`)
+- **Units**: Standard SI (m/s² for acceleration, deg/s for gyroscope, °C for temperature)
+- **Calibration**: Persistent via SharedPreferences (`data/com.micropythonos.sensors/config.json`)
+- **Thread-safe**: Uses locks for concurrent access
+- **Auto-detection**: Identifies IMU type via chip ID registers
+- **Desktop**: Functions return `None` (graceful fallback) on desktop builds
+
+### Driver Locations
+
+- **QMI8658**: `lib/mpos/hardware/drivers/qmi8658.py`
+- **WSEN_ISDS**: `lib/mpos/hardware/drivers/wsen_isds.py`
+- **Board init**: `lib/mpos/board/waveshare_esp32_s3_touch_lcd_2.py` and `lib/mpos/board/fri3d_2024.py`
+
 ## Animations and Game Loops
 
 MicroPythonOS supports frame-based animations and game loops using the TaskHandler event system. This pattern is used for games, particle effects, and smooth animations.

 ## Common Utilities and Helpers
 
 **SharedPreferences**: Persistent key-value storage per app
-```python
-from mpos.config import SharedPreferences
-
-# Basic usage
-prefs = SharedPreferences("com.example.myapp")
-value = prefs.get_string("key", "default_value")
-number = prefs.get_int("count", 0)
-data = prefs.get_dict("data", {})
-
-# Save preferences
-editor = prefs.edit()
-editor.put_string("key", "value")
-editor.put_int("count", 42)
-editor.put_dict("data", {"key": "value"})
-editor.commit()
-
-# Using constructor defaults (reduces config file size)
-# Values matching defaults are not saved to disk
-prefs = SharedPreferences("com.example.myapp", defaults={
-    "brightness": -1,
-    "volume": 50,
-    "theme": "dark"
-})
-
-# Returns constructor default (-1) if not stored
-brightness = prefs.get_int("brightness")  # Returns -1
-
-# Method defaults override constructor defaults
-brightness = prefs.get_int("brightness", 100)  # Returns 100
-
-# Stored values override all defaults
-prefs.edit().put_int("brightness", 75).commit()
-brightness = prefs.get_int("brightness")  # Returns 75
-
-# Setting to default value removes it from storage (auto-cleanup)
-prefs.edit().put_int("brightness", -1).commit()
-# brightness is no longer stored in config.json, saves space
-```
-
-**Multi-mode apps with merged defaults**:
-
-Apps with multiple operating modes can define separate defaults dictionaries and merge them based on the current mode. The camera app demonstrates this pattern with normal and QR scanning modes:
-
-```python
-# Define defaults in your settings class
-class CameraSettingsActivity:
-    # Common defaults shared by all modes
-    COMMON_DEFAULTS = {
-        "brightness": 1,
-        "contrast": 0,
-        "saturation": 0,
-        "hmirror": False,
-        "vflip": True,
-        # ... 20 more common settings
-    }
-
-    # Normal mode specific defaults
-    NORMAL_DEFAULTS = {
-        "resolution_width": 240,
-        "resolution_height": 240,
-        "colormode": True,
-        "ae_level": 0,
-        "raw_gma": True,
-    }
 
-    # QR scanning mode specific defaults
-    SCANQR_DEFAULTS = {
-        "resolution_width": 960,
-        "resolution_height": 960,
-        "colormode": False,  # Grayscale for better QR detection
-        "ae_level": 2,       # Higher exposure
-        "raw_gma": False,    # Better contrast
-    }
-
-# Merge defaults based on mode when initializing
-def load_settings(self):
-    if self.scanqr_mode:
-        # Merge common + scanqr defaults
-        scanqr_defaults = {}
-        scanqr_defaults.update(CameraSettingsActivity.COMMON_DEFAULTS)
-        scanqr_defaults.update(CameraSettingsActivity.SCANQR_DEFAULTS)
-        self.prefs = SharedPreferences(
-            self.PACKAGE,
-            filename="config_scanqr.json",
-            defaults=scanqr_defaults
-        )
-    else:
-        # Merge common + normal defaults
-        normal_defaults = {}
-        normal_defaults.update(CameraSettingsActivity.COMMON_DEFAULTS)
-        normal_defaults.update(CameraSettingsActivity.NORMAL_DEFAULTS)
-        self.prefs = SharedPreferences(
-            self.PACKAGE,
-            defaults=normal_defaults
-        )
-
-    # Now all get_*() calls can omit default arguments
-    width = self.prefs.get_int("resolution_width")  # Mode-specific default
-    brightness = self.prefs.get_int("brightness")   # Common default
-```
-
-**Benefits of this pattern**:
-- Single source of truth for all 30 camera settings defaults
-- Mode-specific config files (`config.json`, `config_scanqr.json`)
-- ~90% reduction in config file size (only non-default values stored)
-- Eliminates hardcoded defaults throughout the codebase
-- No need to pass defaults to every `get_int()`/`get_bool()` call
-- Self-documenting code with clear defaults dictionaries
+📖 User Documentation: See [docs/frameworks/preferences.md](../docs/docs/frameworks/preferences.md) for complete guide with constructor defaults, multi-mode patterns, and auto-cleanup behavior.
 
-**Note**: Use `dict.update()` instead of `{**dict1, **dict2}` for MicroPython compatibility (dictionary unpacking syntax not supported).
+**Implementation**: `lib/mpos/config.py` - SharedPreferences class with get/put methods for strings, ints, bools, lists, and dicts. Values matching constructor defaults are automatically removed from storage (space optimization).
 
 **Intent system**: Launch activities and pass data

-MicroPythonOS provides a centralized audio service called **AudioFlinger** (Android-inspired) that manages audio playback across different hardware outputs.
-
-### Supported Audio Devices
-
-- **I2S**: Digital audio output for WAV file playback (Fri3d badge, Waveshare board)
-- **Buzzer**: PWM-based tone/ringtone playback (Fri3d badge only)
-- **Both**: Simultaneous I2S and buzzer support
-- **Null**: No audio (desktop/Linux)
-
-### Basic Usage
-
-**Playing WAV files**:
-```python
-import mpos.audio.audioflinger as AudioFlinger
-
-# Play music file
-success = AudioFlinger.play_wav(
-    "M:/sdcard/music/song.wav",
-    stream_type=AudioFlinger.STREAM_MUSIC,
-    volume=80,
-    on_complete=lambda msg: print(msg)
-)
-
-if not success:
-    print("Audio playback rejected (higher priority stream active)")
-```
-
-**Playing RTTTL ringtones**:
-```python
-# Play notification sound via buzzer
-rtttl = "Nokia:d=4,o=5,b=225:8e6,8d6,8f#,8g#,8c#6,8b,d,8p,8b,8a,8c#,8e"
-AudioFlinger.play_rtttl(
-    rtttl,
-    stream_type=AudioFlinger.STREAM_NOTIFICATION
-)
-```
-
-**Volume control**:
-```python
-AudioFlinger.set_volume(70)  # 0-100
-volume = AudioFlinger.get_volume()
-```
-
-**Stopping playback**:
-```python
-AudioFlinger.stop()
-```
-
-### Audio Focus Priority
-
-AudioFlinger implements priority-based audio focus (Android-inspired):
-- **STREAM_ALARM** (priority 2): Highest priority
-- **STREAM_NOTIFICATION** (priority 1): Medium priority
-- **STREAM_MUSIC** (priority 0): Lowest priority
-
-Higher priority streams automatically interrupt lower priority streams. Equal or lower priority streams are rejected while a stream is playing.

-## LED Control (LightsManager)
-
-MicroPythonOS provides a simple LED control service for NeoPixel RGB LEDs (Fri3d badge only).
-
-### Basic Usage
-
-**Check availability**:
-```python
-import mpos.lights as LightsManager
-
-if LightsManager.is_available():
-    print(f"LEDs available: {LightsManager.get_led_count()}")
-```
-
-**Control individual LEDs**:
-```python
-# Set LED 0 to red (buffered)
-LightsManager.set_led(0, 255, 0, 0)
-
-# Set LED 1 to green
-LightsManager.set_led(1, 0, 255, 0)
-
-# Update hardware
-LightsManager.write()
-```
+- **Hardware abstraction**: Supports I2S (GPIO 2, 47, 16) and Buzzer (GPIO 46 on Fri3d)
+- **Audio focus**: 3-tier priority system (ALARM > NOTIFICATION > MUSIC)
+- **Configuration**: `data/com.micropythonos.settings/config.json` key: `audio_device`
 
-**Control all LEDs**:
-```python
-# Set all LEDs to blue
-LightsManager.set_all(0, 0, 255)
-LightsManager.write()
-
-# Clear all LEDs (black)
-LightsManager.clear()
-LightsManager.write()
-```
+### Critical Code Locations
 
-**Notification colors**:
-```python
-# Convenience method for common colors
-LightsManager.set_notification_color("red")
-LightsManager.set_notification_color("green")
-# Available: red, green, blue, yellow, orange, purple, white
-```

-### Custom Animations
-
-LightsManager provides one-shot control only (no built-in animations). Apps implement custom animations using the `update_frame()` pattern:
-
-```python
-import time
-import mpos.lights as LightsManager
-
-def blink_pattern():
-    for _ in range(5):
-        LightsManager.set_all(255, 0, 0)
-        LightsManager.write()
-        time.sleep_ms(200)
-
-        LightsManager.clear()
-        LightsManager.write()
-        time.sleep_ms(200)
-
-def rainbow_cycle():
-    colors = [
-        (255, 0, 0),    # Red
-        (255, 128, 0),  # Orange
-        (255, 255, 0),  # Yellow
-        (0, 255, 0),    # Green
-        (0, 0, 255),    # Blue
-    ]
-
-    for i, color in enumerate(colors):
-        LightsManager.set_led(i, *color)
-
-    LightsManager.write()
-```
-
-**For frame-based LED animations**, use the TaskHandler event system:
-
-```python
-import mpos.ui
-import time
-
-class LEDAnimationActivity(Activity):
-    last_time = 0
-    led_index = 0
+## LED Control (LightsManager)
 
-    def onResume(self, screen):
-        self.last_time = time.ticks_ms()
-        mpos.ui.task_handler.add_event_cb(self.update_frame, 1)
+MicroPythonOS provides LED control for NeoPixel RGB LEDs (Fri3d badge only).
 
-    def onPause(self, screen):
-        mpos.ui.task_handler.remove_event_cb(self.update_frame)
-        LightsManager.clear()
-        LightsManager.write()
+**📖 User Documentation**: See [docs/frameworks/lights-manager.md](../docs/docs/frameworks/lights-manager.md) for complete API reference, animation patterns, and examples.
 
-    def update_frame(self, a, b):
-        current_time = time.ticks_ms()
-        delta_time = time.ticks_diff(current_time, self.last_time) / 1000.0
-        self.last_time = current_time
-
-        # Update animation every 0.5 seconds
-        if delta_time > 0.5:
-            LightsManager.clear()
-            LightsManager.set_led(self.led_index, 0, 255, 0)
-            LightsManager.write()
-            self.led_index = (self.led_index + 1) % LightsManager.get_led_count()
-```

-## Sensor System (SensorManager)
-
-MicroPythonOS provides a unified sensor framework called **SensorManager** (Android-inspired) that provides easy access to motion sensors (accelerometer, gyroscope) and temperature sensors across different hardware platforms.
-
-### Supported Sensors
-
-**IMU Sensors:**
-- **QMI8658** (Waveshare ESP32-S3): Accelerometer, Gyroscope, Temperature
-- **WSEN_ISDS** (Fri3d Camp 2024 Badge): Accelerometer, Gyroscope
-
-**Temperature Sensors:**
-- **ESP32 MCU Temperature**: Internal SoC temperature sensor
-- **IMU Chip Temperature**: QMI8658 chip temperature
-
-### Basic Usage
-
-**Check availability and read sensors**:
-```python
-import mpos.sensor_manager as SensorManager
-
-# Check if sensors are available
-if SensorManager.is_available():
-    # Get sensors
-    accel = SensorManager.get_default_sensor(SensorManager.TYPE_ACCELEROMETER)
-    gyro = SensorManager.get_default_sensor(SensorManager.TYPE_GYROSCOPE)
-    temp = SensorManager.get_default_sensor(SensorManager.TYPE_SOC_TEMPERATURE)
-
-    # Read data (returns standard SI units)
-    accel_data = SensorManager.read_sensor(accel)  # Returns (x, y, z) in m/s²
-    gyro_data = SensorManager.read_sensor(gyro)    # Returns (x, y, z) in deg/s
-    temperature = SensorManager.read_sensor(temp)  # Returns °C
-
-    if accel_data:
-        ax, ay, az = accel_data
-        print(f"Acceleration: {ax:.2f}, {ay:.2f}, {az:.2f} m/s²")
-```
-
-### Sensor Types
-
-```python
-# Motion sensors
-SensorManager.TYPE_ACCELEROMETER    # m/s² (meters per second squared)
-SensorManager.TYPE_GYROSCOPE        # deg/s (degrees per second)
-
-# Temperature sensors
-SensorManager.TYPE_SOC_TEMPERATURE  # °C (MCU internal temperature)
-SensorManager.TYPE_IMU_TEMPERATURE  # °C (IMU chip temperature)
-```
-
-### Tilt-Controlled Game Example
-
-```python
-from mpos.app.activity import Activity
-import mpos.sensor_manager as SensorManager
-import mpos.ui
-import time
-
-class TiltBallActivity(Activity):
-    def onCreate(self):
-        self.screen = lv.obj()
-
-        # Get accelerometer
-        self.accel = SensorManager.get_default_sensor(SensorManager.TYPE_ACCELEROMETER)
-
-        # Create ball UI
-        self.ball = lv.obj(self.screen)
-        self.ball.set_size(20, 20)
-        self.ball.set_style_radius(10, 0)
-
-        # Physics state
-        self.ball_x = 160.0
-        self.ball_y = 120.0
-        self.ball_vx = 0.0
-        self.ball_vy = 0.0
-        self.last_time = time.ticks_ms()
-
-        self.setContentView(self.screen)
-
-    def onResume(self, screen):
-        self.last_time = time.ticks_ms()
-        mpos.ui.task_handler.add_event_cb(self.update_physics, 1)
-
-    def onPause(self, screen):
-        mpos.ui.task_handler.remove_event_cb(self.update_physics)
-
-    def update_physics(self, a, b):
-        current_time = time.ticks_ms()
-        delta_time = time.ticks_diff(current_time, self.last_time) / 1000.0
-        self.last_time = current_time
-
-        # Read accelerometer
-        accel = SensorManager.read_sensor(self.accel)
-        if accel:
-            ax, ay, az = accel
-
-            # Apply acceleration to velocity
-            self.ball_vx += (ax * 5.0) * delta_time
-            self.ball_vy -= (ay * 5.0) * delta_time  # Flip Y
+### Critical Code Locations
 
-            # Update position
-            self.ball_x += self.ball_vx
-            self.ball_y += self.ball_vy

-            # Update ball position
-            self.ball.set_pos(int(self.ball_x), int(self.ball_y))
-```
-
-### Calibration
-
-Calibration removes sensor drift and improves accuracy. The device must be **stationary** during calibration.
-
-```python
-# Calibrate accelerometer and gyroscope
-accel = SensorManager.get_default_sensor(SensorManager.TYPE_ACCELEROMETER)
-gyro = SensorManager.get_default_sensor(SensorManager.TYPE_GYROSCOPE)
-
-# Calibrate (100 samples, device must be flat and still)
-accel_offsets = SensorManager.calibrate_sensor(accel, samples=100)
-gyro_offsets = SensorManager.calibrate_sensor(gyro, samples=100)
-
-# Calibration is automatically saved to SharedPreferences
-# and loaded on next boot
-```
-
-### Performance Recommendations
-
-**Polling rate recommendations:**
-- **Games**: 20-30 Hz (responsive but not excessive)
-- **UI feedback**: 10-15 Hz (smooth for tilt UI)
-- **Background monitoring**: 1-5 Hz (screen rotation, pedometer)
-
-```python
-# ❌ BAD: Poll every frame (60 Hz)
-def update_frame(self, a, b):
-    accel = SensorManager.read_sensor(self.accel)  # Too frequent!
-
-# ✅ GOOD: Poll every other frame (30 Hz)
-def update_frame(self, a, b):
-    self.frame_count += 1
-    if self.frame_count % 2 == 0:
-        accel = SensorManager.read_sensor(self.accel)
-```

 ## Build System
 
+### Development Workflow (IMPORTANT)
+
+**For most development, you do NOT need to rebuild the firmware!**
+
+When you run `scripts/install.sh`, it copies files from `internal_filesystem/` to the device storage. These files override the frozen filesystem because the storage paths are first in `sys.path`. This means:
+
+```bash
+# Fast development cycle (recommended):
+# 1. Edit Python files in internal_filesystem/
+# 2. Install to device:
+./scripts/install.sh waveshare-esp32-s3-touch-lcd-2
+
+# That's it! Your changes are live on the device.
+```
+
+**You only need to rebuild firmware (`./scripts/build_mpos.sh esp32`) when:**
+- Testing the frozen `lib/` for production releases
+- Modifying C extension modules (`c_mpos/`, `secp256k1-embedded-ecdh/`)
+- Changing MicroPython core or LVGL bindings
+- Creating a fresh firmware image for distribution
+
+**Desktop development** always uses the unfrozen files, so you never need to rebuild for Python changes:
+```bash
+# Edit internal_filesystem/ files
+./scripts/run_desktop.sh  # Changes are immediately active
+```
+
 ### Building Firmware
 
 The main build script is `scripts/build_mpos.sh`:

 ### Development Workflow (IMPORTANT)
 
-**For most development, you do NOT need to rebuild the firmware!**
+**⚠️ CRITICAL: Desktop vs Hardware Testing**
 
-When you run `scripts/install.sh`, it copies files from `internal_filesystem/` to the device storage. These files override the frozen filesystem because the storage paths are first in `sys.path`. This means:
+📖 **See**: [docs/os-development/running-on-desktop.md](../docs/docs/os-development/running-on-desktop.md) for complete guide.
 
+**Desktop testing (recommended for ALL Python development):**
 ```bash
-# Fast development cycle (recommended):
-# 1. Edit Python files in internal_filesystem/
-# 2. Install to device:
-./scripts/install.sh waveshare-esp32-s3-touch-lcd-2
+# 1. Edit files in internal_filesystem/
+nano internal_filesystem/builtin/apps/com.micropythonos.settings/assets/settings.py
+
+# 2. Run on desktop - changes are IMMEDIATELY active!
+./scripts/run_desktop.sh
 
-# That's it! Your changes are live on the device.
+# That's it! NO build, NO install needed.
 ```
 
-**You only need to rebuild firmware (`./scripts/build_mpos.sh esp32`) when:**
-- Testing the frozen `lib/` for production releases
-- Modifying C extension modules (`c_mpos/`, `secp256k1-embedded-ecdh/`)
-- Changing MicroPython core or LVGL bindings
-- Creating a fresh firmware image for distribution
+**❌ DO NOT run `./scripts/install.sh` for desktop testing!** It's only for hardware deployment.
+
+The desktop binary runs **directly from `internal_filesystem/`**, so any Python file changes are instantly available. This is the fastest development cycle.
 
-**Desktop development** always uses the unfrozen files, so you never need to rebuild for Python changes:
+**Hardware deployment (only after desktop testing):**
 ```bash
-# Edit internal_filesystem/ files
-./scripts/run_desktop.sh  # Changes are immediately active
+# Deploy to physical ESP32 device via USB/serial
+./scripts/install.sh waveshare-esp32-s3-touch-lcd-2
 ```
 
+This copies files from `internal_filesystem/` to device storage, which overrides the frozen filesystem.
+
+**When you need to rebuild firmware (`./scripts/build_mpos.sh`):**
+- Modifying C extension modules (`c_mops/`, `secp256k1-embedded-ecdh/`)
+- Changing MicroPython core or LVGL bindings
+- Testing frozen filesystem for production releases
+- Creating firmware for distribution
+
+**For 99% of development work on Python code**: Just edit `internal_filesystem/` and run `./scripts/run_desktop.sh`.
+

Subject: [PATCH 120/859] TaskManager: without new thread works but blocks REPL

aiorepl (asyncio REPL) works but it's pretty limited

It's probably fine for production, but it means the user has to sys.exit()
in aiorepl before landing on the real interactive REPL, with asyncio tasks stopped.

+download_manager.py - Centralized download management for MicroPythonOS
+
+Provides async HTTP download with flexible output modes:
+- Download to memory (returns bytes)
+- Download to file (returns bool)
+- Streaming with chunk callback (returns bool)
+
+Features:
+- Shared aiohttp.ClientSession for performance
+- Automatic session lifecycle management
+- Thread-safe session access
+- Retry logic (3 attempts per chunk, 10s timeout)
+- Progress tracking
+- Resume support via Range headers
+
+Example:
+    from mpos import DownloadManager
+
+    # Download to memory
+    data = await DownloadManager.download_url("https://api.example.com/data.json")
+
+    # Download to file with progress

+## Task Management (TaskManager)
+
+MicroPythonOS provides a centralized async task management service called **TaskManager** for managing background operations.
+
+**📖 User Documentation**: See [docs/frameworks/task-manager.md](../docs/docs/frameworks/task-manager.md) for complete API reference, patterns, and examples.
+
+### Implementation Details (for Claude Code)
+
+- **Location**: `lib/mpos/task_manager.py`
+- **Pattern**: Wrapper around `uasyncio` module
+- **Key methods**: `create_task()`, `sleep()`, `sleep_ms()`, `wait_for()`, `notify_event()`
+- **Thread model**: All tasks run on main asyncio event loop (cooperative multitasking)
+
+### Quick Example
+
+```python
+from mpos import TaskManager, DownloadManager
+
+class MyActivity(Activity):
+    def onCreate(self):
+        # Launch background task
+        TaskManager.create_task(self.download_data())
+
+    async def download_data(self):
+        # Download with timeout
+        try:
+            data = await TaskManager.wait_for(
+                DownloadManager.download_url(url),
+                timeout=10
+            )
+            self.update_ui(data)
+        except asyncio.TimeoutError:
+            print("Download timed out")
+```
+
+### Critical Code Locations
+
+- Task manager: `lib/mpos/task_manager.py`
+- Used throughout OS for async operations (downloads, WebSockets, sensors)
+
+## HTTP Downloads (DownloadManager)
+
+MicroPythonOS provides a centralized HTTP download service called **DownloadManager** for async file downloads.
+
+**📖 User Documentation**: See [docs/frameworks/download-manager.md](../docs/docs/frameworks/download-manager.md) for complete API reference, patterns, and examples.
+
+### Implementation Details (for Claude Code)
+
+- **Location**: `lib/mpos/net/download_manager.py`
+- **Pattern**: Module-level singleton (similar to `audioflinger.py`, `battery_voltage.py`)
+- **Session management**: Automatic lifecycle (lazy init, auto-cleanup when idle)
+- **Thread-safe**: Uses `_thread.allocate_lock()` for session access
+- **Three output modes**: Memory (bytes), File (bool), Streaming (callbacks)
+- **Features**: Retry logic (3 attempts), progress tracking, resume support (Range headers)
+
+### Quick Example
+
+```python
+from mpos import DownloadManager
+
+# Download to memory
+data = await DownloadManager.download_url("https://api.example.com/data.json")
+
+# Download to file with progress
+async def on_progress(percent):
+    print(f"Progress: {percent}%")
+
+success = await DownloadManager.download_url(
+    "https://example.com/file.bin",
+    outfile="/sdcard/file.bin",
+    progress_callback=on_progress
+)
+```
+
+### Critical Code Locations
+
+- Download manager: `lib/mpos/net/download_manager.py`
+- Used by: AppStore, OSUpdate, and any app needing HTTP downloads
+
 ## Audio System (AudioFlinger)
 
 MicroPythonOS provides a centralized audio service called **AudioFlinger** for managing audio playback.

 Network testing helper module for MicroPythonOS.
 
 This module provides mock implementations of network-related modules
-for testing without requiring actual network connectivity. These mocks
-are designed to be used with dependency injection in the classes being tested.
+for testing without requiring actual network connectivity.
+
+NOTE: This module re-exports mocks from mpos.testing for backward compatibility.
+New code should import directly from mpos.testing.

Subject: [PATCH 153/859] fix(ui/testing): use send_event for reliable label
 clicks in tests

click_label() now detects clickable parent containers and uses
send_event(lv.EVENT.CLICKED) instead of simulate_click() for more
reliable UI test interactions.

This fixes sporadic failures in test_graphical_imu_calibration_ui_bug.py
where clicking "Check IMU Calibration" would sometimes fail because
simulate_click() wasn't reliably triggering the click event on the
parent container.

- Add use_send_event parameter to click_label() (default: True)
- Detect clickable parent containers and send events directly to them
- Verified with 15 consecutive test runs (100% pass rate)

+# MicroPythonOS Testing Guide
+
+This directory contains the test suite for MicroPythonOS. Tests can run on both desktop (for fast iteration) and on-device (for hardware verification).
+
+## Quick Start
+
+```bash

+└── README.md               # This file
+```
+
+### Testing Modules
+
+MicroPythonOS provides two testing modules:
+
+1. **`mpos.testing`** - Hardware and system mocks
+   - Location: `internal_filesystem/lib/mpos/testing/`
+   - Use for: Mocking hardware (Pin, PWM, I2S, NeoPixel), network, async operations
+   
+2. **`mpos.ui.testing`** - LVGL/UI testing utilities
+   - Location: `internal_filesystem/lib/mpos/ui/testing.py`
+   - Use for: UI interaction, screenshots, widget inspection
+
+## Base Test Classes
+
+### GraphicalTestBase
+
+Base class for all graphical (LVGL) tests. Provides:
+- Automatic screen creation/cleanup
+- Screenshot capture
+- Widget finding utilities
+- Custom assertions
+
+```python
+from base import GraphicalTestBase
+
+class TestMyUI(GraphicalTestBase):
+    def test_something(self):
+        # self.screen is already created
+        label = lv.label(self.screen)
+        label.set_text("Hello")
+        
+        self.wait_for_render()
+        self.assertTextPresent("Hello")
+        self.capture_screenshot("my_test.raw")
+```
+
+**Key Methods:**
+- `wait_for_render(iterations=5)` - Process LVGL tasks
+- `capture_screenshot(filename)` - Save screenshot
+- `find_label_with_text(text)` - Find label widget
+- `click_button(button)` - Simulate button click
+- `assertTextPresent(text)` - Assert text is on screen
+- `assertWidgetVisible(widget)` - Assert widget is visible
+
+### KeyboardTestBase
+
+Extends GraphicalTestBase for keyboard tests. Provides:
+- Keyboard and textarea creation
+- Reliable keyboard button clicking
+- Textarea assertions
+
+```python
+from base import KeyboardTestBase
+
+class TestMyKeyboard(KeyboardTestBase):
+    def test_typing(self):
+        self.create_keyboard_scene()
+        
+        self.click_keyboard_button("h")
+        self.click_keyboard_button("i")
+        
+        self.assertTextareaText("hi")
+```
+
+**Key Methods:**
+- `create_keyboard_scene()` - Create textarea + MposKeyboard
+- `click_keyboard_button(text)` - Click keyboard button reliably
+- `type_text(text)` - Type a string
+- `get_textarea_text()` - Get textarea content
+- `clear_textarea()` - Clear textarea
+- `assertTextareaText(expected)` - Assert textarea content
+- `assertTextareaEmpty()` - Assert textarea is empty
+
+## Mock Classes
+
+Import mocks from `mpos.testing`:
+
+```python
+from mpos.testing import (
+    # Hardware mocks
+    MockMachine,      # Full machine module mock
+    MockPin,          # GPIO pins
+    MockPWM,          # PWM for buzzer
+    MockI2S,          # Audio I2S
+    MockTimer,        # Hardware timers
+    MockNeoPixel,     # LED strips
+    MockSocket,       # Network sockets
+    
+    # MPOS mocks
+    MockTaskManager,  # Async task management
+    MockDownloadManager,  # HTTP downloads
+    
+    # Network mocks
+    MockNetwork,      # WiFi/network module
+    MockRequests,     # HTTP requests
+    MockResponse,     # HTTP responses
+    
+    # Utility mocks
+    MockTime,         # Time functions
+    MockJSON,         # JSON parsing
+    
+    # Helpers
+    inject_mocks,     # Inject mocks into sys.modules
+    create_mock_module,  # Create mock module
+)
+```
+
+### Injecting Mocks
+
+```python
+from mpos.testing import inject_mocks, MockMachine, MockNetwork
+
+# Inject before importing modules that use hardware
+inject_mocks({
+    'machine': MockMachine(),
+    'network': MockNetwork(connected=True),
+})
+
+# Now import the module under test
+from mpos.hardware import some_module
+```
+
+### Mock Examples
+
+**MockNeoPixel:**
+```python
+from mpos.testing import MockNeoPixel, MockPin
+
+pin = MockPin(5)
+leds = MockNeoPixel(pin, 10)
+
+leds[0] = (255, 0, 0)  # Set first LED to red
+leds.write()
+
+assert leds.write_count == 1
+assert leds[0] == (255, 0, 0)
+```
+
+**MockRequests:**
+```python
+from mpos.testing import MockRequests
+
+mock_requests = MockRequests()
+mock_requests.set_next_response(
+    status_code=200,
+    text='{"status": "ok"}',
+    headers={'Content-Type': 'application/json'}
+)
+
+response = mock_requests.get("https://api.example.com/data")
+assert response.status_code == 200
+```
+
+**MockTimer:**
+```python
+from mpos.testing import MockTimer
+
+timer = MockTimer(0)
+timer.init(period=1000, mode=MockTimer.PERIODIC, callback=my_callback)
+
+# Manually trigger for testing
+timer.trigger()
+
+# Or trigger all timers
+MockTimer.trigger_all()
+```
+
+## Test Naming Conventions
+
+- `test_*.py` - Standard unit tests
+- `test_graphical_*.py` - Tests requiring LVGL/UI (detected by unittest.sh)
+- `manual_test_*.py` - Manual tests (not run automatically)
+
+## Writing New Tests
+
+### Simple Unit Test
+
+```python
+import unittest
+
+class TestMyFeature(unittest.TestCase):
+    def test_something(self):
+        result = my_function()
+        self.assertEqual(result, expected)
+```
+
+### Graphical Test
+
+```python
+from base import GraphicalTestBase
+import lvgl as lv
+
+class TestMyUI(GraphicalTestBase):
+    def test_button_click(self):
+        button = lv.button(self.screen)
+        label = lv.label(button)
+        label.set_text("Click Me")
+        
+        self.wait_for_render()
+        self.click_button(button)
+        
+        # Verify result
+```
+
+### Keyboard Test
+
+```python
+from base import KeyboardTestBase
+
+class TestMyKeyboard(KeyboardTestBase):
+    def test_input(self):
+        self.create_keyboard_scene()
+        
+        self.type_text("hello")
+        self.assertTextareaText("hello")
+        
+        self.click_keyboard_button("Enter")
+```
+
+### Test with Mocks
+
+```python
+import unittest
+from mpos.testing import MockNetwork, inject_mocks
+
+class TestNetworkFeature(unittest.TestCase):
+    def setUp(self):
+        self.mock_network = MockNetwork(connected=True)
+        inject_mocks({'network': self.mock_network})
+    
+    def test_connected(self):
+        from my_module import check_connection
+        self.assertTrue(check_connection())
+    
+    def test_disconnected(self):
+        self.mock_network.set_connected(False)
+        from my_module import check_connection
+        self.assertFalse(check_connection())
+```
+
+## Best Practices
+
+1. **Use base classes** - Extend `GraphicalTestBase` or `KeyboardTestBase` for UI tests
+2. **Use mpos.testing mocks** - Don't create inline mocks; use the centralized ones
+3. **Clean up in tearDown** - Base classes handle this, but custom tests should clean up
+4. **Don't include `if __name__ == '__main__'`** - The test runner handles this
+5. **Use descriptive test names** - `test_keyboard_q_button_works` not `test_1`
+6. **Add docstrings** - Explain what the test verifies and why
+
+## Debugging Tests
+
+```bash
+# Run with verbose output
+./tests/unittest.sh tests/test_my_test.py
+
+# Run with GDB (desktop only)
+gdb --args ./lvgl_micropython/build/lvgl_micropy_unix -X heapsize=8M tests/test_my_test.py
+```
+
+## Screenshots
+
+Screenshots are saved to `tests/screenshots/` in raw format. Convert to PNG:
+
+```bash
+cd tests/screenshots
+./convert_to_png.sh
+```

-# CLAUDE.md
-
-This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
-
-## Project Overview
-
-MicroPythonOS is an embedded operating system that runs on ESP32 hardware (particularly the Waveshare ESP32-S3-Touch-LCD-2) and desktop Linux/macOS. It provides an LVGL-based UI framework with an Android-inspired app architecture featuring Activities, Intents, and a PackageManager.
-
-The OS supports:
-- Touch and non-touch input devices (keyboard/joystick navigation)
-- Camera with QR decoding (using quirc)
-- WiFi connectivity
-- Over-the-air (OTA) firmware updates
-- App installation via MPK packages
-- Bitcoin Lightning and Nostr protocols
-
-## Repository Structure
-
-### Core Directories
-
-- `internal_filesystem/`: The runtime filesystem containing the OS and apps
-  - `boot.py`: Hardware initialization for ESP32-S3-Touch-LCD-2
-  - `boot_unix.py`: Desktop-specific boot initialization
-  - `main.py`: UI initialization, theme setup, and launcher start
-  - `lib/mpos/`: Core OS library (apps, config, UI, content management)
-  - `apps/`: User-installed apps (symlinks to external app repos)
-  - `builtin/`: System apps frozen into the firmware (launcher, appstore, settings, etc.)
-  - `data/`: Static data files
-  - `sdcard/`: SD card mount point
-
-- `lvgl_micropython/`: Submodule containing LVGL bindings for MicroPython
-- `micropython-camera-API/`: Submodule for camera support
-- `micropython-nostr/`: Submodule for Nostr protocol
-- `c_mpos/`: C extension modules (includes quirc for QR decoding)
-- `secp256k1-embedded-ecdh/`: Submodule for cryptographic operations
-- `manifests/`: Build manifests defining what gets frozen into firmware
-- `freezeFS/`: Files to be frozen into the built-in filesystem
-- `scripts/`: Build and deployment scripts
-- `tests/`: Test suite (both unit tests and manual tests)
-
-### Key Architecture Components
-
-**App System**: Similar to Android
-- Apps are identified by reverse-domain names (e.g., `com.micropythonos.camera`)
-- Each app has a `META-INF/MANIFEST.JSON` with metadata and activity definitions
-- Activities extend `mpos.app.activity.Activity` class (import: `from mpos.app.activity import Activity`)
-- Apps implement `onCreate()` to set up their UI and `onDestroy()` for cleanup
-- Activity lifecycle: `onCreate()` → `onStart()` → `onResume()` → `onPause()` → `onStop()` → `onDestroy()`
-- Apps are packaged as `.mpk` files (zip archives)
-- Built-in system apps (frozen into firmware): launcher, appstore, settings, wifi, osupdate, about
-
-**UI Framework**: Built on LVGL 9.3.0
-- `mpos.ui.topmenu`: Notification bar and drawer (top menu)
-- `mpos.ui.display`: Root screen initialization
-- Gesture support: left-edge swipe for back, top-edge swipe for menu
-- Theme system with configurable colors and light/dark modes
-- Focus groups for keyboard/joystick navigation
-
-**Content Management**:
-- `PackageManager`: Install/uninstall/query apps
-- `Intent`: Launch activities with action/category filters
-- `SharedPreferences`: Per-app key-value storage (similar to Android) - see [docs/frameworks/preferences.md](../docs/docs/frameworks/preferences.md)
-
-**Hardware Abstraction**:
-- `boot.py` configures SPI, I2C, display (ST7789), touchscreen (CST816S), and battery ADC
-- Platform detection via `sys.platform` ("esp32" vs others)
-- Different boot files per hardware variant (boot_fri3d-2024.py, etc.)
-
-### Webcam Module (Desktop Only)
-
-The `c_mpos/src/webcam.c` module provides webcam support for desktop builds using the V4L2 API.
-
-**Resolution Adaptation**:
-- Automatically queries supported YUYV resolutions from the webcam using V4L2 API
-- Supports all 23 ESP32 camera resolutions via intelligent cropping/padding
-- **Center cropping**: When requesting smaller than available (e.g., 240x240 from 320x240)
-- **Black border padding**: When requesting larger than maximum supported
-- Always returns exactly the requested dimensions for API consistency
-
-**Behavior**:
-- On first init, queries device for supported resolutions using `VIDIOC_ENUM_FRAMESIZES`
-- Selects smallest capture resolution ≥ requested dimensions (minimizes memory/bandwidth)
-- Converts YUYV to RGB565 (color) or grayscale during capture
-- Caches supported resolutions to avoid re-querying device
-
-**Examples**:
-
-*Cropping (common case)*:
-- Request: 240x240 (not natively supported)
-- Capture: 320x240 (nearest supported YUYV resolution)
-- Process: Extract center 240x240 region
-- Result: 240x240 frame with centered content
-
-*Padding (rare case)*:
-- Request: 1920x1080
-- Capture: 1280x720 (webcam maximum)
-- Process: Center 1280x720 content in 1920x1080 buffer with black borders
-- Result: 1920x1080 frame (API contract maintained)
-
-**Performance**:
-- Exact matches use fast path (no cropping overhead)
-- Cropped resolutions add ~5-10% CPU overhead
-- Padded resolutions add ~3-5% CPU overhead (memset + center placement)
-- V4L2 buffers sized for capture resolution, conversion buffers sized for output
-
-**Implementation Details**:
-- YUYV format: 2 pixels per macropixel (4 bytes: Y0 U Y1 V)
-- Crop offsets must be even for proper YUYV alignment
-- Center crop formula: `offset = (capture_dim - output_dim) / 2`, then align to even
-- Supported resolutions cached in `supported_resolutions_t` structure
-- Separate tracking of `capture_width/height` (from V4L2) vs `output_width/height` (user requested)
-
-**File Location**: `c_mpos/src/webcam.c` (C extension module)
-
-## Build System
-
-### Development Workflow (IMPORTANT)
-
-**⚠️ CRITICAL: Desktop vs Hardware Testing**
-
-📖 **See**: [docs/os-development/running-on-desktop.md](../docs/docs/os-development/running-on-desktop.md) for complete guide.
-
-**Desktop testing (recommended for ALL Python development):**
-```bash
-# 1. Edit files in internal_filesystem/
-nano internal_filesystem/builtin/apps/com.micropythonos.settings/assets/settings.py
-
-# 2. Run on desktop - changes are IMMEDIATELY active!
-./scripts/run_desktop.sh
-
-# That's it! NO build, NO install needed.
-```
-
-**❌ DO NOT run `./scripts/install.sh` for desktop testing!** It's only for hardware deployment.
-
-The desktop binary runs **directly from `internal_filesystem/`**, so any Python file changes are instantly available. This is the fastest development cycle.
-
-**Hardware deployment (only after desktop testing):**
-```bash
-# Deploy to physical ESP32 device via USB/serial
-./scripts/install.sh waveshare-esp32-s3-touch-lcd-2
-```
-
-This copies files from `internal_filesystem/` to device storage, which overrides the frozen filesystem.
-
-**When you need to rebuild firmware (`./scripts/build_mpos.sh`):**
-- Modifying C extension modules (`c_mops/`, `secp256k1-embedded-ecdh/`)
-- Changing MicroPython core or LVGL bindings
-- Testing frozen filesystem for production releases
-- Creating firmware for distribution
-
-**For 99% of development work on Python code**: Just edit `internal_filesystem/` and run `./scripts/run_desktop.sh`.
-
-### Building Firmware
-
-The main build script is `scripts/build_mpos.sh`:
-
-```bash
-# Build for desktop (Linux)
-./scripts/build_mpos.sh unix
-
-# Build for desktop (macOS)
-./scripts/build_mpos.sh macOS
-
-# Build for ESP32-S3 hardware (works on both waveshare and fri3d variants)
-./scripts/build_mpos.sh esp32
-```
-
-**Targets**:
-- `esp32`: ESP32-S3 hardware (supports waveshare-esp32-s3-touch-lcd-2 and fri3d-2024)
-- `unix`: Linux desktop
-- `macOS`: macOS desktop
-
-**Note**: The build system automatically includes the frozen filesystem with all built-in apps and libraries. No separate dev/prod distinction exists anymore.
-
-The build system uses `lvgl_micropython/make.py` which wraps MicroPython's build system. It:
-1. Fetches SDL tags for desktop builds
-2. Patches manifests to include camera and asyncio support
-3. Creates symlinks for C modules (secp256k1, c_mpos)
-4. Runs the lvgl_micropython build with appropriate flags
-
-**ESP32 build configuration**:
-- Board: `ESP32_GENERIC_S3` with `SPIRAM_OCT` variant
-- Display driver: `st7789`
-- Input device: `cst816s`
-- OTA enabled with 4MB partition size (16MB total flash)
-- Dual-core threading enabled (no GIL)
-- User C modules: camera, secp256k1, c_mpos/quirc
-
-**Desktop build configuration**:
-- Display: `sdl_display`
-- Input: `sdl_pointer`, `sdl_keyboard`
-- Compiler flags: `-g -O0 -ggdb -ljpeg` (debug symbols enabled)
-- STRIP is disabled to keep debug symbols
-
-### Building and Bundling Apps
-
-Apps can be bundled into `.mpk` files:
-```bash
-./scripts/bundle_apps.sh
-```
-
-### Running on Desktop
-
-```bash
-# Run normally (starts launcher)
-./scripts/run_desktop.sh
-
-# Run a specific Python script directly
-./scripts/run_desktop.sh path/to/script.py
-
-# Run a specific app by name
-./scripts/run_desktop.sh com.micropythonos.camera
-```
-
-**Important environment variables**:
-- `HEAPSIZE`: Set heap size (default 8M, matches ESP32-S3 PSRAM). Increase for memory-intensive apps
-- `SDL_WINDOW_FULLSCREEN`: Set to `true` for fullscreen mode
-
-The script automatically selects the correct binary (`lvgl_micropy_unix` or `lvgl_micropy_macOS`) and runs from the `internal_filesystem/` directory.
-
-## Deploying to Hardware
-
-### Flashing Firmware
-
-```bash
-# Flash firmware over USB
-./scripts/flash_over_usb.sh
-```
-
-### Installing Files to Device
-
-```bash
-# Install all files to device (boot.py, main.py, lib/, apps/, builtin/)
-./scripts/install.sh waveshare-esp32-s3-touch-lcd-2
-
-# Install a single app to device
-./scripts/install.sh waveshare-esp32-s3-touch-lcd-2 camera
-```
-
-Uses `mpremote` from MicroPython tools to copy files over serial connection.
-
-## Testing
-
-### Running Tests
-
-Tests are in the `tests/` directory. There are two types: unit tests and manual tests.
-
-**Unit tests** (automated, run on desktop or device):
-```bash
-# Run all unit tests on desktop
-./tests/unittest.sh
-
-# Run a specific test file on desktop
-./tests/unittest.sh tests/test_shared_preferences.py
-./tests/unittest.sh tests/test_intent.py
-./tests/unittest.sh tests/test_package_manager.py
-./tests/unittest.sh tests/test_graphical_start_app.py
-
-# Run a specific test on connected device (via mpremote)
-./tests/unittest.sh tests/test_shared_preferences.py --ondevice
-
-# Run all tests on connected device
-./tests/unittest.sh --ondevice
-```
-
-The `unittest.sh` script:
-- Automatically detects the platform (Linux/macOS) and uses the correct binary
-- Sets up the proper paths and heapsize
-- Can run tests on device using `mpremote` with the `--ondevice` flag
-- Runs all `test_*.py` files when no argument is provided
-- On device, assumes the OS is already running (boot.py and main.py already executed), so tests run against the live system
-- Test infrastructure (graphical_test_helper.py) is automatically installed by `scripts/install.sh`
-
-**Available unit test modules**:
-- `test_shared_preferences.py`: Tests for `mpos.config.SharedPreferences` (configuration storage)
-- `test_intent.py`: Tests for `mpos.content.intent.Intent` (intent creation, extras, flags)
-- `test_package_manager.py`: Tests for `PackageManager` (version comparison, app discovery)
-- `test_graphical_start_app.py`: Tests for app launching (graphical test with proper boot/main initialization)
-- `test_graphical_about_app.py`: Graphical test that verifies About app UI and captures screenshots
-
-**Graphical tests** (UI verification with screenshots):
-```bash
-# Run graphical tests on desktop
-./tests/unittest.sh tests/test_graphical_about_app.py
-
-# Run graphical tests on device
-./tests/unittest.sh tests/test_graphical_about_app.py --ondevice
-
-# Convert screenshots from raw RGB565 to PNG
-cd tests/screenshots
-./convert_to_png.sh  # Converts all .raw files in the directory
-```
-
-Graphical tests use `tests/graphical_test_helper.py` which provides utilities like:
-- `wait_for_render()`: Wait for LVGL to process UI events
-- `capture_screenshot()`: Take screenshot as RGB565 raw data
-- `find_label_with_text()`: Find labels containing specific text
-- `verify_text_present()`: Verify expected text is on screen
-
-Screenshots are saved as `.raw` files (RGB565 format) and can be converted to PNG using `tests/screenshots/convert_to_png.sh`
-
-**Manual tests** (interactive, for hardware-specific features):
-- `manual_test_camera.py`: Camera and QR scanning
-- `manual_test_nostr_asyncio.py`: Nostr protocol
-- `manual_test_nwcwallet*.py`: Lightning wallet connectivity (Alby, Cashu)
-- `manual_test_lnbitswallet.py`: LNbits wallet integration
-- `test_websocket.py`: WebSocket functionality
-- `test_multi_connect.py`: Multiple concurrent connections
-
-Run manual tests with:
-```bash
-./scripts/run_desktop.sh tests/manual_test_camera.py
-```
-
-### Writing New Tests
-
-**Unit test guidelines**:
-- Use Python's `unittest` module (compatible with MicroPython)
-- Place tests in `tests/` directory with `test_*.py` naming
-- Use `setUp()` and `tearDown()` for test fixtures
-- Clean up any created files/directories in `tearDown()`
-- Tests should be runnable on desktop (unix build) without hardware dependencies
-- Use descriptive test names: `test_<what_is_being_tested>`
-- Group related tests in test classes
-- **IMPORTANT**: Do NOT end test files with `if __name__ == '__main__': unittest.main()` - the `./tests/unittest.sh` script handles running tests and capturing exit codes. Including this will interfere with test execution.
-
-**Example test structure**:
-```python
-import unittest
-from mpos.some_module import SomeClass
-
-class TestSomeClass(unittest.TestCase):
-    def setUp(self):
-        # Initialize test fixtures
-        pass
-
-    def tearDown(self):
-        # Clean up after test
-        pass
-
-    def test_some_functionality(self):
-        # Arrange
-        obj = SomeClass()
-        # Act
-        result = obj.some_method()
-        # Assert
-        self.assertEqual(result, expected_value)
-```
-
-## Development Workflow
-
-### Creating a New App
-
-1. Create app directory: `internal_filesystem/apps/com.example.myapp/`
-2. Create `META-INF/MANIFEST.JSON` with app metadata and activities
-3. Create `assets/` directory for Python code
-4. Create main activity file extending `Activity` class
-5. Implement `onCreate()` method to build UI
-6. Optional: Create `res/` directory for resources (icons, images)
-
-**Minimal app structure**:
-```
-com.example.myapp/
-├── META-INF/
-│   └── MANIFEST.JSON
-├── assets/
-│   └── main_activity.py
-└── res/
-    └── mipmap-mdpi/
-        └── icon_64x64.png
-```
-
-**Minimal Activity code**:
-```python
-from mpos.app.activity import Activity
-import lvgl as lv
-
-class MainActivity(Activity):
-    def onCreate(self):
-        screen = lv.obj()
-        label = lv.label(screen)
-        label.set_text('Hello World!')
-        label.center()
-        self.setContentView(screen)
-```
-
-See `internal_filesystem/apps/com.micropythonos.helloworld/` for a minimal example and built-in apps in `internal_filesystem/builtin/apps/` for more complex examples.
-
-### Testing App Changes
-
-For rapid iteration on desktop:
-```bash
-# Build desktop version (only needed once)
-./scripts/build_mpos.sh unix
-
-# Install filesystem to device (run after code changes)
-./scripts/install.sh
-
-# Or run directly on desktop
-./scripts/run_desktop.sh com.example.myapp
-```
-
-### Debugging
-
-Desktop builds include debug symbols by default. Use GDB:
-```bash
-gdb --args ./lvgl_micropython/build/lvgl_micropy_unix -X heapsize=8M -v -i -c "$(cat boot_unix.py main.py)"
-```
-
-For ESP32 debugging, enable core dumps:
-```bash
-./scripts/core_dump_activate.sh
-```
-
-## Important Constraints
-
-### Memory Management
-
-ESP32-S3 has 8MB PSRAM. Memory-intensive operations:
-- Camera images consume ~2.5MB per frame
-- LVGL image cache must be managed with `lv.image.cache_drop(None)`
-- Large UI components should be created/destroyed rather than hidden
-- Use `gc.collect()` strategically after deallocating large objects
-
-### Threading
-
-- Main UI/LVGL operations must run on main thread
-- Background tasks use `_thread.start_new_thread()`
-- Stack size: 16KB for ESP32, 24KB for desktop (see `mpos.apps.good_stack_size()`)
-- Use `mpos.ui.async_call()` to safely invoke UI operations from background threads
-
-### Async Operations
-
-- OS uses `uasyncio` for networking (WebSockets, HTTP, Nostr)
-- WebSocket library is custom `websocket.py` using uasyncio
-- HTTP uses `aiohttp` package (in `lib/aiohttp/`)
-- Async tasks are throttled per frame to prevent memory overflow
-
-### File Paths
-
-- Use `M:/path/to/file` prefix for LVGL file operations (registered in main.py)
-- Absolute paths for Python imports
-- Apps run with their directory added to `sys.path`
-
-## Build Dependencies
-
-The build requires all git submodules checked out recursively:
-```bash
-git submodule update --init --recursive
-```
-
-**Desktop dependencies**: See `.github/workflows/build.yml` for full list including:
-- SDL2 development libraries
-- Mesa/EGL libraries
-- libjpeg
-- Python 3.8+
-- cmake, ninja-build
-
-## Manifest System
-
-Manifests define what gets frozen into firmware:
-- `manifests/manifest.py`: ESP32 production builds
-- `manifests/manifest_fri3d-2024.py`: Fri3d Camp 2024 Badge variant
-- `manifests/manifest_unix.py`: Desktop builds
-
-Manifests use `freeze()` directives to include files in the frozen filesystem. Frozen files are baked into the firmware and cannot be modified at runtime.
-
-## Version Management
-
-Versions are tracked in:
-- `CHANGELOG.md`: User-facing changelog with release history
-- App versions in `META-INF/MANIFEST.JSON` files
-- OS update system checks `hardware_id` from `mpos.info.get_hardware_id()`
-
-Current stable version: 0.3.3 (as of latest CHANGELOG entry)

-## Common Utilities and Helpers
-
-**SharedPreferences**: Persistent key-value storage per app
-
-📖 User Documentation: See [docs/frameworks/preferences.md](../docs/docs/frameworks/preferences.md) for complete guide with constructor defaults, multi-mode patterns, and auto-cleanup behavior.
-
-**Implementation**: `lib/mpos/config.py` - SharedPreferences class with get/put methods for strings, ints, bools, lists, and dicts. Values matching constructor defaults are automatically removed from storage (space optimization).
-
-**Intent system**: Launch activities and pass data
-```python
-from mpos.content.intent import Intent
-
-# Launch activity by name
-intent = Intent()
-intent.setClassName("com.micropythonos.camera", "Camera")
-self.startActivity(intent)
-
-# Launch with extras
-intent.putExtra("key", "value")
-self.startActivityForResult(intent, self.handle_result)
-
-def handle_result(self, result):
-    if result["result_code"] == Activity.RESULT_OK:
-        data = result["data"]
-```
-
-**UI utilities**:
-- `mpos.ui.async_call(func, *args, **kwargs)`: Safely call UI operations from background threads
-- `mpos.ui.back_screen()`: Navigate back to previous screen
-- `mpos.ui.focus_direction`: Keyboard/joystick navigation helpers
-- `mpos.ui.anim`: Animation utilities
-
-### Keyboard and Focus Navigation
-
-MicroPythonOS supports keyboard/joystick navigation through LVGL's focus group system. This allows users to navigate apps using arrow keys and select items with Enter.
-
-**Basic focus handling pattern**:
-```python
-def onCreate(self):
-    # Get the default focus group
-    focusgroup = lv.group_get_default()
-    if not focusgroup:
-        print("WARNING: could not get default focusgroup")
-
-    # Create a clickable object
-    button = lv.button(screen)
-
-    # Add focus/defocus event handlers
-    button.add_event_cb(lambda e, b=button: self.focus_handler(b), lv.EVENT.FOCUSED, None)
-    button.add_event_cb(lambda e, b=button: self.defocus_handler(b), lv.EVENT.DEFOCUSED, None)
-
-    # Add to focus group (enables keyboard navigation)
-    if focusgroup:
-        focusgroup.add_obj(button)
-
-def focus_handler(self, obj):
-    """Called when object receives focus"""
-    obj.set_style_border_color(lv.theme_get_color_primary(None), lv.PART.MAIN)
-    obj.set_style_border_width(2, lv.PART.MAIN)
-    obj.scroll_to_view(True)  # Scroll into view if needed
-
-def defocus_handler(self, obj):
-    """Called when object loses focus"""
-    obj.set_style_border_width(0, lv.PART.MAIN)
-```
-
-**Key principles**:
-- Get the default focus group with `lv.group_get_default()`
-- Add objects to the focus group to make them keyboard-navigable
-- Use `lv.EVENT.FOCUSED` to highlight focused elements (usually with a border)
-- Use `lv.EVENT.DEFOCUSED` to remove highlighting
-- Use theme color for consistency: `lv.theme_get_color_primary(None)`
-- Call `scroll_to_view(True)` to auto-scroll focused items into view
-- The focus group automatically handles arrow key navigation between objects
-
-**Example apps with focus handling**:
-- **Launcher** (`builtin/apps/com.micropythonos.launcher/assets/launcher.py`): App icons are focusable
-- **Settings** (`builtin/apps/com.micropythonos.settings/assets/settings_app.py`): Settings items are focusable
-- **Connect 4** (`apps/com.micropythonos.connect4/assets/connect4.py`): Game columns are focusable

-## Animations and Game Loops
-
-MicroPythonOS supports frame-based animations and game loops using the TaskHandler event system. This pattern is used for games, particle effects, and smooth animations.
-
-### The update_frame() Pattern
-
-The core pattern involves:
-1. Registering a callback that fires every frame
-2. Calculating delta time for framerate-independent physics
-3. Updating object positions and properties
-4. Rendering to LVGL objects
-5. Unregistering when animation completes
-
-**Basic structure**:
-```python
-from mpos.apps import Activity
-import mpos.ui
-import time
-import lvgl as lv
-
-class MyAnimatedApp(Activity):
-    last_time = 0
-
-    def onCreate(self):
-        # Set up your UI
-        self.screen = lv.obj()
-        # ... create objects ...
-        self.setContentView(self.screen)
-
-    def onResume(self, screen):
-        # Register the frame callback
-        self.last_time = time.ticks_ms()
-        mpos.ui.task_handler.add_event_cb(self.update_frame, 1)
-
-    def onPause(self, screen):
-        # Unregister when app goes to background
-        mpos.ui.task_handler.remove_event_cb(self.update_frame)
-
-    def update_frame(self, a, b):
-        # Calculate delta time for framerate independence
-        current_time = time.ticks_ms()
-        delta_ms = time.ticks_diff(current_time, self.last_time)
-        delta_time = delta_ms / 1000.0  # Convert to seconds
-        self.last_time = current_time
-
-        # Update your animation/game logic here
-        # Use delta_time to make physics framerate-independent
-```
-
-### Framerate-Independent Physics
-
-All movement and physics should be multiplied by `delta_time` to ensure consistent behavior regardless of framerate:
-
-```python
-# Example from QuasiBird game
-GRAVITY = 200  # pixels per second²
-PIPE_SPEED = 100  # pixels per second
-
-def update_frame(self, a, b):
-    current_time = time.ticks_ms()
-    delta_time = time.ticks_diff(current_time, self.last_time) / 1000.0
-    self.last_time = current_time
-
-    # Update velocity with gravity
-    self.bird_velocity += self.GRAVITY * delta_time
-
-    # Update position with velocity
-    self.bird_y += self.bird_velocity * delta_time
-
-    # Update bird sprite position
-    self.bird_img.set_y(int(self.bird_y))
-
-    # Move pipes
-    for pipe in self.pipes:
-        pipe.x -= self.PIPE_SPEED * delta_time
-```
-
-**Key principles**:
-- Constants define rates in "per second" units (pixels/second, degrees/second)
-- Multiply all rates by `delta_time` when applying them
-- This ensures objects move at the same speed regardless of framerate
-- Use `time.ticks_ms()` and `time.ticks_diff()` for timing (handles rollover correctly)
-
-### Object Pooling for Performance
-
-Pre-create LVGL objects and reuse them instead of creating/destroying during animation:
-
-```python
-# Example from LightningPiggy confetti animation
-MAX_CONFETTI = 21
-confetti_images = []
-confetti_pieces = []
-used_img_indices = set()
-
-def onStart(self, screen):
-    # Pre-create all image objects (hidden initially)
-    for i in range(self.MAX_CONFETTI):
-        img = lv.image(lv.layer_top())
-        img.set_src(f"{self.ASSET_PATH}confetti{i % 5}.png")
-        img.add_flag(lv.obj.FLAG.HIDDEN)
-        self.confetti_images.append(img)
-
-def _spawn_one(self):
-    # Find a free image slot
-    for idx, img in enumerate(self.confetti_images):
-        if img.has_flag(lv.obj.FLAG.HIDDEN) and idx not in self.used_img_indices:
-            break
-    else:
-        return  # No free slot
-
-    # Create particle data (not LVGL object)
-    piece = {
-        'img_idx': idx,
-        'x': random.uniform(0, self.SCREEN_WIDTH),
-        'y': 0,
-        'vx': random.uniform(-80, 80),
-        'vy': random.uniform(-150, 0),
-        'rotation': 0,
-        'scale': 1.0,
-        'age': 0.0
-    }
-    self.confetti_pieces.append(piece)
-    self.used_img_indices.add(idx)
-
-def update_frame(self, a, b):
-    delta_time = time.ticks_diff(time.ticks_ms(), self.last_time) / 1000.0
-    self.last_time = time.ticks_ms()
-
-    new_pieces = []
-    for piece in self.confetti_pieces:
-        # Update physics
-        piece['x'] += piece['vx'] * delta_time
-        piece['y'] += piece['vy'] * delta_time
-        piece['vy'] += self.GRAVITY * delta_time
-        piece['rotation'] += piece['spin'] * delta_time
-        piece['age'] += delta_time
-
-        # Update LVGL object
-        img = self.confetti_images[piece['img_idx']]
-        img.remove_flag(lv.obj.FLAG.HIDDEN)
-        img.set_pos(int(piece['x']), int(piece['y']))
-        img.set_rotation(int(piece['rotation'] * 10))

-    self.confetti_pieces = new_pieces
-```
-
-**Object pooling benefits**:
-- Avoid memory allocation/deallocation during animation
-- Reuse LVGL image objects (expensive to create)
-- Hide/show objects instead of create/delete
-- Track which slots are in use with a set
-- Separate particle data (Python dict) from rendering (LVGL object)
-
-### Particle Systems and Effects
-
-**Staggered spawning** (spawn particles over time instead of all at once):
-```python
-def start_animation(self):
-    self.spawn_timer = 0
-    self.spawn_interval = 0.15  # seconds between spawns
-    mpos.ui.task_handler.add_event_cb(self.update_frame, 1)
-
-def update_frame(self, a, b):
-    delta_time = time.ticks_diff(time.ticks_ms(), self.last_time) / 1000.0
-
-    # Staggered spawning
-    self.spawn_timer += delta_time
-    if self.spawn_timer >= self.spawn_interval:
-        self.spawn_timer = 0
-        for _ in range(random.randint(1, 2)):
-            if len(self.particles) < self.MAX_PARTICLES:
-                self._spawn_one()
-```
-
-**Particle lifecycle** (age, scale, death):
-```python
-piece = {
-    'x': x, 'y': y,
-    'vx': random.uniform(-80, 80),
-    'vy': random.uniform(-150, 0),
-    'spin': random.uniform(-500, 500),  # degrees/sec
-    'age': 0.0,
-    'lifetime': random.uniform(5.0, 10.0),
-    'rotation': random.uniform(0, 360),
-    'scale': 1.0
-}
-
-# In update_frame
-piece['age'] += delta_time
-piece['scale'] = max(0.3, 1.0 - (piece['age'] / piece['lifetime']) * 0.7)
-
-# Death check
-dead = (
-    piece['x'] < -60 or piece['x'] > SCREEN_WIDTH + 60 or
-    piece['y'] > SCREEN_HEIGHT + 60 or
-    piece['age'] > piece['lifetime']
-)
-```
-
-### Game Loop Patterns
-
-**Scrolling backgrounds** (parallax and tiling):
-```python
-# Parallax clouds (multiple layers at different speeds)
-CLOUD_SPEED = 30  # pixels/sec (slower than foreground)
-cloud_positions = [50, 180, 320]
-
-for i, cloud_img in enumerate(self.cloud_images):
-    self.cloud_positions[i] -= self.CLOUD_SPEED * delta_time
-
-    # Wrap around when off-screen
-    if self.cloud_positions[i] < -60:
-        self.cloud_positions[i] = SCREEN_WIDTH + 20
-
-    cloud_img.set_x(int(self.cloud_positions[i]))
-
-# Tiled ground (infinite scrolling)
-self.ground_x -= self.PIPE_SPEED * delta_time
-self.ground_img.set_offset_x(int(self.ground_x))  # LVGL handles wrapping
-```
-
-**Object pooling for game entities**:
-```python
-# Pre-create pipe images
-MAX_PIPES = 4
-pipe_images = []
-
-for i in range(MAX_PIPES):
-    top_pipe = lv.image(screen)
-    top_pipe.set_src("M:path/to/pipe.png")
-    top_pipe.set_rotation(1800)  # 180 degrees * 10
-    top_pipe.add_flag(lv.obj.FLAG.HIDDEN)
-
-    bottom_pipe = lv.image(screen)
-    bottom_pipe.set_src("M:path/to/pipe.png")
-    bottom_pipe.add_flag(lv.obj.FLAG.HIDDEN)
-
-    pipe_images.append({"top": top_pipe, "bottom": bottom_pipe, "in_use": False})
-
-# Update visible pipes
-def update_pipe_images(self):
-    for pipe_img in self.pipe_images:
-        pipe_img["in_use"] = False
-
-    for i, pipe in enumerate(self.pipes):
-        if i < self.MAX_PIPES:
-            pipe_imgs = self.pipe_images[i]
-            pipe_imgs["in_use"] = True
-            pipe_imgs["top"].remove_flag(lv.obj.FLAG.HIDDEN)
-            pipe_imgs["top"].set_pos(int(pipe.x), int(pipe.gap_y - 200))
-            pipe_imgs["bottom"].remove_flag(lv.obj.FLAG.HIDDEN)
-            pipe_imgs["bottom"].set_pos(int(pipe.x), int(pipe.gap_y + pipe.gap_size))
-
-    # Hide unused slots
-    for pipe_img in self.pipe_images:
-        if not pipe_img["in_use"]:
-            pipe_img["top"].add_flag(lv.obj.FLAG.HIDDEN)
-            pipe_img["bottom"].add_flag(lv.obj.FLAG.HIDDEN)
-```
-
-**Collision detection**:
-```python
-def check_collision(self):
-    # Boundaries
-    if self.bird_y <= 0 or self.bird_y >= SCREEN_HEIGHT - 40 - self.bird_size:
-        return True
-
-    # AABB (Axis-Aligned Bounding Box) collision
-    bird_left = self.BIRD_X
-    bird_right = self.BIRD_X + self.bird_size
-    bird_top = self.bird_y
-    bird_bottom = self.bird_y + self.bird_size
-
-    for pipe in self.pipes:
-        pipe_left = pipe.x
-        pipe_right = pipe.x + pipe.width
-
-        # Check horizontal overlap
-        if bird_right > pipe_left and bird_left < pipe_right:
-            # Check if bird is outside the gap
-            if bird_top < pipe.gap_y or bird_bottom > pipe.gap_y + pipe.gap_size:
-                return True
-
-    return False
-```
-
-### Animation Control and Cleanup
-
-**Starting/stopping animations**:
-```python
-def start_animation(self):
-    self.animation_running = True
-    self.last_time = time.ticks_ms()
-    mpos.ui.task_handler.add_event_cb(self.update_frame, 1)
-
-    # Optional: auto-stop after duration
-    lv.timer_create(self.stop_animation, 15000, None).set_repeat_count(1)
-
-def stop_animation(self, timer=None):
-    self.animation_running = False
-    # Don't remove callback yet - let it clean up and remove itself
-
-def update_frame(self, a, b):
-    # ... update logic ...
-
-    # Stop when animation completes
-    if not self.animation_running and len(self.particles) == 0:
-        mpos.ui.task_handler.remove_event_cb(self.update_frame)
-        print("Animation finished")
-```
-
-**Lifecycle integration**:
-```python
-def onResume(self, screen):
-    # Only start if needed (e.g., game in progress)
-    if self.game_started and not self.game_over:
-        self.last_time = time.ticks_ms()
-        mpos.ui.task_handler.add_event_cb(self.update_frame, 1)
-
-def onPause(self, screen):
-    # Always stop when app goes to background
-    mpos.ui.task_handler.remove_event_cb(self.update_frame)
-```
-
-### Performance Tips
-
-1. **Pre-create LVGL objects**: Creating objects during animation causes lag
-2. **Use object pools**: Reuse objects instead of create/destroy
-3. **Limit particle counts**: Use `MAX_PARTICLES` constant (21 is a good default)
-4. **Integer positions**: Convert float positions to int before setting: `img.set_pos(int(x), int(y))`
-5. **Delta time**: Always use delta time for framerate independence
-6. **Layer management**: Use `lv.layer_top()` for overlays (confetti, popups)
-7. **Rotation units**: LVGL rotation is in 1/10 degrees: `set_rotation(int(degrees * 10))`
-8. **Scale units**: LVGL scale is 256 = 100%: `set_scale(int(256 * scale_factor))`
-9. **Hide vs destroy**: Hide objects with `add_flag(lv.obj.FLAG.HIDDEN)` instead of deleting
-10. **Cleanup**: Always unregister callbacks in `onPause()` to prevent memory leaks

Subject: [PATCH 271/859] refactor(appstore): extract DRY helpers and
 consolidate duplicated code

- Extract _apply_default_styles() helper to eliminate 12+ repeated widget style calls
- Extract _add_click_handler() helper to consolidate 6 repeated event registrations
- Consolidate backend config getters into single _get_backend_config() method
- Simplify badgehub_app_to_mpos_app() with safer .get() defaults instead of try-except
- Extract _cleanup_temp_file(), _update_progress(), _show_progress_bar(), _hide_progress_bar() helpers
- Refactor uninstall_app() and download_and_install() to use new progress helpers
- Use getattr() for cleaner attribute checking

Eliminates ~85 lines of duplicated logic while preserving all functionality,
comments, and debug prints. Improves maintainability and code clarity.

 - App framework: simplify MANIFEST.JSON
 - AudioFlinger framework: simplify import, use singleton class
 - Create new SettingsActivity and SettingActivity framework so apps can easily add settings screens with just a few lines of code
+- Create CameraManager framework so apps can easily check whether there is a camera available etc.
 - Improve robustness by catching unhandled app exceptions
 - Improve robustness with custom exception that does not deinit() the TaskHandler
 - Improve robustness by removing TaskHandler callback that throws an uncaught exception

+- Camera app and QR scanning: fix aspect ratio for higher resolutions
+- WiFi app: check 'hidden' in EditNetwork
+- Wifi app: add support for scanning wifi QR codes to 'Add Network'
 - Create new SettingsActivity and SettingActivity framework so apps can easily add settings screens with just a few lines of code
 - Create CameraManager framework so apps can easily check whether there is a camera available etc.
+- Simplify and unify most frameworks to make developing apps easier
 - Improve robustness by catching unhandled app exceptions
 - Improve robustness with custom exception that does not deinit() the TaskHandler
 - Improve robustness by removing TaskHandler callback that throws an uncaught exception
 - Don't rate-limit update_ui_threadsafe_if_foreground
+- Make 'Power Off' button on desktop exit completely

Subject: [PATCH 372/859] Update run_desktop.sh to fix settings being ignored

Script would not be able to start in dark mode, config.json was backed up but never used. config.json is not backed up anymore, change if this is needed still.
We overwrite the auto_start_app if we launch it with a specific app.

Subject: [PATCH 374/859] Reduce size of logo while increasing font size

From 5633 to 3210 bytes while reducing borders around the text.

How:
- import the svg into gimp, rasterized at 266x59 at 130 dpi
- crop it to 240x35 px, making sure to have at least 0.5 pixel border around the content to make sure no half-transparent pixels are cut off
- export as PNG with maximal compression and all options (save resolution, save background color etc) unchecked

Subject: [PATCH 375/859] Reduce size of logo while increasing font size

From 5633 to 3210 bytes while reducing borders around the text.

How:
- import MicroPythonOS-logo-black-long.svg into Gimp, rasterized at 266x59 at 130 dpi
- crop it to 240x35 px, making sure to have at least 0.5 pixel border around the content to make sure no half-transparent pixels are cut off
- export as PNG with maximal compression and all options (like save resolution, save background color) unchecked

Subject: [PATCH 394/859] Harmonize frameworks
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

All frameworks now follow the same singleton class pattern with class methods:

AudioFlinger (already had this pattern)
DownloadManager (refactored)
ConnectivityManager (refactored)
CameraManager (refactored)
SensorManager (refactored)
Pattern Structure:

class FrameworkName:
    _initialized = False
    _instance_data = {}

    @classmethod
    def init(cls, *args, **kwargs):
        """Initialize the framework"""
        cls._initialized = True
        # initialization logic

    @classmethod
    def is_available(cls):
        """Check if framework is available"""
        return cls._initialized

    @classmethod
    def method_name(cls, *args):
        """Framework methods as class methods"""
        # implementation

2. Standardized Imports in __init__.py
All frameworks are now imported consistently as classes:

from .content.package_manager import PackageManager
from .config import SharedPreferences
from .net.connectivity_manager import ConnectivityManager
from .net.wifi_service import WifiService
from .audio.audioflinger import AudioFlinger
from .net.download_manager import DownloadManager
from .task_manager import TaskManager
from .camera_manager import CameraManager
from .sensor_manager import SensorManager
3. Updated Board Initialization Files
Fixed imports in all board files to use the new class-based pattern:

linux.py
fri3d_2024.py
fri3d_2026.py
waveshare_esp32_s3_touch_lcd_2.py
4. Updated UI Components
Fixed topmenu.py to import SensorManager as a class instead of a module.

5. Benefits of This Harmonization
✅ Consistency: All frameworks follow the same pattern - no more mixing of module imports and class imports ✅ Simplicity: Single, clear way to use frameworks - always as classes with class methods ✅ Functionality: All frameworks work identically - init(), is_available(), and other methods are consistent ✅ Maintainability: New developers see one pattern to follow across all frameworks ✅ No Breaking Changes: Apps continue to work without modification (Quasi apps, Lightning Piggy, etc.)

6. Testing
All tests pass successfully, confirming:

Framework initialization works correctly
Board hardware detection functions properly
UI components render without errors
No regressions in existing functionality
The harmonization is complete and production-ready. All frameworks now provide a unified, predictable interface that's easy to understand and extend.

+AppearanceManager - Android-inspired appearance management singleton.

+- Light/dark mode (UI appearance)
+- Theme colors (primary, secondary, accent)
+- UI dimensions (notification bar height, etc.)
+- LVGL theme initialization
+- Keyboard styling workarounds

+This is a singleton implemented using class methods and class variables.
+No instance creation is needed - all methods are class methods.

So this updated one is the old one, but a bit smaller (55x55) like the others.

Subject: [PATCH 460/859] DownloadManager: don't share aiohttp.ClientSession

There is a performance impact, so maybe it should be reintroduced again later,
but for now, let's keep it simple and fix this bug.

+Provides async HTTP downloads with flexible output modes:
 - Download to memory (returns bytes)
 - Download to file (returns bool)
 - Streaming with chunk callback (returns bool)
 
 Features:
-- Shared aiohttp.ClientSession for performance
-- Automatic session lifecycle management
-- Thread-safe session access
 - Retry logic (3 attempts per chunk, 10s timeout)
 - Progress tracking with 2-decimal precision
 - Download speed reporting
 - Resume support via Range headers
 - Network error detection utilities
-
-Class Methods:
-    DownloadManager.download_url(...) - Download with flexible output modes
-    DownloadManager.is_session_active() - Check if session is active
-    DownloadManager.close_session() - Explicitly close session
-    DownloadManager.is_network_error(exception) - Check if error is recoverable
-    DownloadManager.get_resume_position(outfile) - Get file size for resume

Subject: [PATCH 476/859] Add experimental ADC recording

Currently, the file is a bit too small and there are interruptions,
probably from the timer stopping and starting to tweak it.

I guess this should be done in C rather than pure MicroPython.

Subject: [PATCH 484/859] Force M5Stack-Fire board detection for ESP32

M5Stack-Fire board detection should be:

i2c0 = I2C(0, sda=Pin(21), scl=Pin(22))
if {0x68} <= set(i2c0.scan()): # IMU (MPU6886)
    return "m5stack-fire"

But there are some pin incompatibilities between ESP32 and ESP32-S3 boards that don't allow I2C scan.

Subject: [PATCH 485/859] Add support for M5Stack-Fire board

M5Stack-Fire uses an ILI9342 instead of an ILI9341. Therefore, lvgl_micropython should include "_ili9341_init_type3.py".

Subject: [PATCH 489/859] Fix board detection by not using i2c scan

i2c scanning all the devices can confuse some of them,
such as the OV* camera's. Better to selectively scan just the ones
we want to know about, plus, it's also faster.

* https://wiki.odroid.com/odroid_go/odroid_go

What worked:

* Display
* Buttons
* Crossbar
* Wifi
* Battery
* blue LED

TODO:

* Speaker

The blue LED is "coupled" with the button/crossbar press.

Subject: [PATCH 568/859] Enhance ShowBattery and fixes for Odroid-GO battery

Add a "Real-time values" checkbox to ShowBattery app. If checked, then the cache will be clear on
every cycle.

Bugfix: Use `mpos.time.localtime()` to get the "correct" local time with timezone offset.

Changes for Odroid-GO:

The seen "2400" values are at startup the Odroid-GO... After a while the values are somewhere
between 270 and 310... The full range is unknown, yet. But with the new calculation it looks more
realistic, then before ;)

Subject: [PATCH 576/859] AudioManager: add support for adc_mic

This works for init:

AudioManager(i2s_pins=i2s_pins, adc_mic_pin=1)

And then this for recording:

AudioManager.record_wav_adc(file_path="/recording.wav",duration_ms=5000,sample_rate=16000,on_complete=lambda msg: print(f"Finished: {msg}"))

Subject: [PATCH 577/859] imu: Allow access to iio on Linux

Linux phones have IMU units. Allow applications to use them same
way they would access IMU on esp32 based devices. Lightly tested
on PinePhone.

Same applications useful on esp32 (compass, step counter) are likely
to be useful on Linux phones, too.

Subject: [PATCH 580/859] Updates for ODROID-GO (#40)

Setup the "Buzzer" and play intro and outro ;) Don't know if "I2S audio" is possible.

Battery "settings": I tested to run ODROID-GO as long as it's possible. The min. raw ADC value on
ODROID-GO i have seen is 210. So update the calculation.

Fix the boot by moving ODROID-GO below `fri3d_2024` because the device will hard crash on
`fail_save_i2c(sda=9, scl=18)` like:
```
MicroPythonOS 0.8.1 running lib/mpos/main.py
matouch_esp32_s3_spi_ips_2_8_with_camera_ov3660 ?
Try to I2C initialized on sda=39 scl=38
OK
Attempt to write a single byte to I2C bus address 0x14...
No device at this address: [Errno 116] ETIMEDOUT
Attempt to write a single byte to I2C bus address 0x5d...
No device at this address: [Errno 116] ETIMEDOUT
waveshare_esp32_s3_touch_lcd_2 ?
Try to I2C initialized on sda=48 scl=47
Failed: invalid pin
m5stack_fire ?
Try to I2C initialized on sda=21 scl=22
OK
Attempt to write a single byte to I2C bus address 0x68...
No device at this address: [Errno 19] ENODEV
fri3d_2024 ?
Try to I2C initialized on sda=9 scl=18
OK

A fatal error occurred. The crash dump printed below may be used to help
determine what caused it. If you are not already running the most recent
version of MicroPython, consider upgrading. New versions often fix bugs.

To learn more about how to debug and/or report this crash visit the wiki
page at: https://github.com/micropython/micropython/wiki/ESP32-debugging

Subject: [PATCH 601/859] Clean up existing install before extracting .mpk
 (#55)

install_mpk() would fail with EEXIST if the destination folder already
existed from a previous (possibly partial) install, or if a dangling
symlink occupied the path (e.g. a dev symlink whose target was removed).

Before extracting, now remove the destination if it is:
- A real directory (via shutil.rmtree)
- A regular file (via os.remove)
- A symlink, including broken ones (via os.remove as a fallback)

This enables clean reinstalls, updates, and recovery from failed
installs.

Subject: [PATCH 602/859] Fix EEXIST errors in zipfile.py during extraction
 (#54)

When extracting zip archives, os.mkdir() could raise [Errno 17] EEXIST
in two places:

1. makedirs() - A directory might already exist between the path_exists
   check and the os.mkdir() call, or be created by a prior extraction step.

2. _extract_member() - makedirs() may have already created a directory
   when building parent paths for a file entry, and then a separate
   directory entry for the same path triggers os.mkdir() again.

Wrap both os.mkdir() calls in try/except OSError to handle this
gracefully.

Subject: [PATCH 612/859] compass: Add an application for magnetometer /
 accelerometer debugging

This is more of a debugging tool for now, but should point north when
calibrated properly. For best results, place on flat surface and rotate
device few times.

Subject: [PATCH 614/859] columns: simple falling-blocks game

This is a start of falling-blocks game. More improvements are possible
(and some are described in the sources), but this is already
playable. You can try to beat score of 120 :-).

Subject: [PATCH 631/859] Fix MPU6886 X-Axis

MPU6886 is part of M5Stack FIRE. I compare the values from this device with Waveshare
ESP32-S3-Touch-LCD-2: The X-axis values are inverted. Fix this here.

Subject: [PATCH 638/859] stream_wav: restore tweaks

QuasiBird still runs jittery at 22050 hz 16 bit stereo.
Mono is fine, and lower sample rates are fine too.

At max volume, so no volume scaling, the frame rate is quite high
but it still jitters. The question is why...

- does the buffer underrun?
- or does it spend too much time reading from SD card?
- or is the CPU busy?

Solutions:
- offload it to a different core
- do the I2S playback asynchronous

I guess it doesn't make sense tweaking this, as audio plays fine up to 48khz stereo
if no game is being played, just normal GUI updates.

Subject: [PATCH 668/859] Enhance ScanBluetooth app

Add a info column with init information and "unique devices" and "scan" count.

Use `TaskManager` that makes the UI a lot more responsive.

Use better scan settings to maximize detection rate.

Subject: [PATCH 680/859] webrepl: support access from LAN, without internet

Host everything on the device itself, rather than redirecting
to https://micropython.org/webrepl/ because that doesn't work when
there is not internet, including when the device is in Access Point
mode.

This was a bit slow, because of the many files and being pretty large,
but the inline_minify_webrepl.py makes this much better and brings it
down to around 1s to load the page, versus 20 seconds.

The minification also reduces the size from around 160KB to 80KB.

Subject: [PATCH 682/859] navstar: Simple navigation application

It can display GPS information, show arrow to selected point and save
track.

It can use several location sources, including /dev/gnss0; by default,
it is configured with fake nmea source.

Subject: [PATCH 699/859] Initial MPong game commit

This demonstrates native machine code in .mpy files as documented
in https://docs.micropython.org/en/latest/develop/natmod.html

The idea is to make a simple Pong game to demonstrate input from
buttons and touchscreen and output to framebuffer and audio.

Subject: [PATCH 721/859] gyro: add gyroscope test/display application (#76)

* iio: switch to maximum sampling frequency, apply mount matrix

* mag: Apply mount matrix for magnetometer, too

* iio: allow separate path for gyro sensor

* gyro: fork from compass, get drawing back to work

* iio: add todo.

* gyro: gyro seems to work way better on pinephone

* iio: move scale conversion where it belongs

* gyro: rely of iio driver providing right scale of values

* iio: Turn down debugging, but I still get framerate drops

* gyro: add reset and calibration support, introduce vectors, display help image

Subject: [PATCH 723/859] Add support for unPhone 9 (#74)

https://unphone.net/

What worked:

- hx8357d Display and XPT2046 touch screen works
- Turn display backlight on/off via TCA9555 chip
- Buttons

TODOs:

- Use LEDs
- LoRa
- IR

`.../lib/drivers/display/hx8357d/` is a not modified copy from
https://github.com/lvgl-micropython/lvgl_micropython/tree/main/api_drivers/common_api_drivers/display/hx8357d

`.../lib/drivers/indev/xpt2046.py` based on
https://github.com/lvgl-micropython/lvgl_micropython/blob/main/api_drivers/common_api_drivers/indev/xpt2046.py
but is modified: Because of the shared SPI bus for SPI for hx8357d display and xpt2046 touch
controller. For this i add the management of `CS` pins for reading the touch controller.
Let's discuss how to add this to upstream in
https://github.com/lvgl-micropython/lvgl_micropython/issues/536

Subject: [PATCH 816/859] Checkin
 internal_filesystem/builtin/html/webrepl_inlined_minified.html

It gets generated by it's a small file that doesn't change often
and when users download internal_filesystem/ from git (to run a
statically compiled Linux build, for example) they need this.

Subject: [PATCH 855/859] New App: "ESPNowChat" simple chat app between devices
 (#86)

Just send messages via https://docs.micropython.org/en/latest/library/espnow.html to all devices via
broadcast address and display all messages that are send from other devices...

Some limitations: All devices must send on the same WiFi channel.

From 96164fe4c5426775d68db60961e8e9ed73d1823a Mon Sep 17 00:00:00 2001

Subject: [PATCH 857/859] feat: add M5Stack Core2 board support (#91)

Add hardware support for M5Stack Core2 (ESP32-D0WDQ6-V3):

New files:
- drivers/power/axp192.py: AXP192 power management IC driver handling
  voltage regulation (DCDC1/3, LDO2/3), GPIO control (LCD/touch reset,
  speaker enable), battery monitoring via ADC, and charging control.
- mpos/board/m5stack_core2.py: Board initialization including ILI9342C
  display (SPI), FT6336U capacitive touch (I2C), NS4168 I2S speaker,
  SPM1423 PDM microphone, MPU6886 IMU, and AXP192-based battery
  voltage reading.

Modified files:
- mpos/main.py: Add Core2 detection via AXP192 I2C probe (0x34) in
  detect_board(). Guard ESP32-S3 specific GPIO probes (pins 10/11,
  39/38, 48/47) with chip variant check to prevent WDT reset on ESP32.

Hardware peripherals supported:
- Display: ILI9342C 320x240 via SPI (SCLK=18, MOSI=23, DC=15, CS=5)
- Touch: FT6336U via shared I2C host 0 (SDA=21, SCL=22, addr=0x38)
- Power: AXP192 via shared I2C host 0 (addr=0x34)
- Audio: NS4168 speaker (I2S: BCLK=12, LRCK=0, DATA=2)
- Mic: SPM1423 (PDM: CLK=0, DATA=34)
- IMU: MPU6886 via shared I2C host 0 (addr=0x68)
- Battery: Read via AXP192 ADC (no dedicated ADC pin needed)

All I2C devices share a single hardware I2C(0) controller. LCD reset
and backlight are controlled via AXP192 GPIO4 and DCDC3 respectively.

Tested on M5Stack Core2 (original version).

Subject: [PATCH 858/859] Add international number format setting (#94)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* Fix desktop run: handle missing _webrepl module gracefully

The WebServer import chain (mpos/__init__.py → webserver.py →
webrepl_http.py) requires the _webrepl C module which is only
available on ESP32 builds. This causes an ImportError on desktop/Unix
systems, preventing the entire mpos package from loading.

Wrap the import in try/except so desktop builds can still run.
main.py already has a similar guard around WebServer.auto_start().

Add a system-wide number format preference to the Settings app,
allowing users to choose their preferred decimal and thousands
separators. Follows the TimeZone pattern with a NumberFormat
utility class that any app can import.

Available formats:
- 1,234.56 (US/UK)
- 1.234,56 (Europe)
- 1 234,56 (French)
- 1'234.56 (Swiss)
- 1_234.56 (Tech)
- 1234.56 / 1234,56 (No thousands separator)

New files:
- lib/mpos/number_format.py — NumberFormat class with format_number()
- tests/test_number_format.py — 14 unit tests
