Subject: [PATCH 01/17] examples: Update uasyncio_example1.py to LVGL v9 API.

- Replace move_foreground() with move_to_index() for v9 compatibility
- Change lv.indev_get_act() to lv.indev_active()
- Update del_async() to delete_async()
- Update set_ready_cb() to set_completed_cb()

These changes align with the LVGL v9 API naming conventions.

+# LVGL MicroPython Examples
+
+This directory contains comprehensive examples demonstrating LVGL (Light and Versatile Graphics Library) usage with MicroPython bindings.
+
+## Quick Start
+
+All examples are compatible with LVGL v9 API. To run an example:
+
+```bash
+# Unix port (with SDL for GUI simulation)
+cd /path/to/micropython/ports/unix
+./build-lvgl/micropython /path/to/examples/example_name.py
+
+# ESP32 port (upload to device)
+# Copy the example to your ESP32 and run it
+```
+
+## Examples Overview
+
+### Basic Examples
+
+- **`generic-st77xx-with-xpt2046.py`**: Simple button example for ST77XX displays with XPT2046 touch
+- **`fb_test.py`**: Linux framebuffer test with basic button and label
+- **`example1.py`**: Comprehensive platform-agnostic example with display initialization
+- **`example3.py`**: Multi-widget example with sliders, LEDs, buttons, and keyboard
+
+### Advanced Examples
+
+- **`advanced_demo.py`**: Complex multi-platform demo with themes, animations, and charts
+- **`custom_widget_example.py`**: Custom widget class creation and theming
+- **`uasyncio_example1.py`**: Async/await integration with LVGL using uasyncio
+
+### Specialized Examples
+
+- **`png_example.py`**: PNG image loading and display with drag functionality
+- **`Dynamic_loading_font_example.py`**: Loading custom binary fonts for multiple languages
+
+### Migration Guide
+
+- **`LvglV8ToV9MigrationGuide.md`**: Comprehensive guide for migrating from LVGL v8 to v9 API
+
+## Platform Support
+
+Examples support multiple platforms:
+
+- **Unix/Linux**: SDL-based simulation
+- **ESP32**: With various display drivers (ILI9341, ST77XX)
+- **STM32**: Built-in display support
+- **Raspberry Pi Pico**: RP2 platform with SPI displays
+
+## Display Driver Integration
+
+Examples demonstrate integration with various display drivers:
+
+- **ILI9341**: Common SPI TFT display
+- **ST77XX**: ST7789/ST7735 family displays
+- **SDL**: Cross-platform simulation
+- **Framebuffer**: Linux framebuffer support
+
+## Touch Input Support
+
+Touch input examples include:
+
+- **XPT2046**: Resistive touch controller
+- **Built-in touch**: Platform-specific touch sensors
+- **Mouse simulation**: SDL mouse input
+
+## Key Features Demonstrated
+
+### Widgets
+- Buttons, labels, sliders, LEDs
+- Text areas and keyboards
+- Charts and progress indicators
+- Images and custom graphics
+
+### Event Handling
+- Button clicks and touch events
+- Value change events
+- Custom event callbacks
+- Async event processing
+
+### Styling and Theming
+- Custom styles and themes
+- Color and gradient management
+- Shadow and border effects
+- Layout and alignment
+
+### Advanced Features
+- Custom widget creation
+- Font loading and text rendering
+- Image decoding (PNG)
+- Animation systems
+- Memory management
+
+## Requirements
+
+### Common Requirements
+- MicroPython with LVGL bindings
+- Appropriate display driver for your hardware
+- Sufficient RAM for graphics operations
+
+### Platform-Specific Requirements
+
+**Unix/Linux:**
+- SDL2 development libraries
+- X11 or Wayland display server
+
+**ESP32:**
+- ESP-IDF or Arduino framework
+- SPI display hardware
+- Touch controller (optional)
+
+**STM32:**
+- STM32 development board with display
+- Touch sensor support
+
+## Error Handling
+
+All examples include comprehensive error handling:
+- Missing driver detection
+- File loading failures
+- Platform compatibility checks
+- Graceful fallbacks when resources unavailable
+
+## Best Practices
+
+Examples demonstrate LVGL best practices:
+
+1. **Proper initialization**: LVGL init before any operations
+2. **Resource management**: Proper cleanup and memory management
+3. **Cross-platform compatibility**: Platform detection and appropriate drivers
+4. **Error handling**: Graceful failure modes
+5. **Code organization**: Clear structure and documentation
+
+## Troubleshooting
+
+### Common Issues
+
+1. **Import errors**: Ensure all required drivers are available
+2. **Display not showing**: Check display driver initialization
+3. **Touch not working**: Verify touch driver configuration
+4. **Memory errors**: Increase heap size or reduce graphics complexity
+
+### Debug Tips
+
+- Enable verbose output in examples for debugging
+- Check LVGL configuration (lv_conf.h)
+- Verify platform compatibility
+- Test with simpler examples first
+
+## Contributing
+
+When adding new examples:
+
+1. Follow existing code style and structure
+2. Include comprehensive docstrings
+3. Add error handling and platform detection
+4. Update this README with new example descriptions
+5. Test on multiple platforms when possible
+
+## License
+
+Examples are provided under the same license as the LVGL MicroPython bindings.
