# Implementation Summary: Waveshare ESP32-S3-AUDIO-Board + 1.47" Touch LCD
|
||
|
||
## ✅ Implementation Complete
|
||
|
||
All features have been successfully implemented for the Waveshare ESP32-S3-AUDIO-Board with the 1.47" Touch LCD display.
|
||
|
||
## What Was Implemented
|
||
|
||
### 1. Display Configuration ✅
|
||
**File:** `xiaozhi-esp32/main/boards/waveshare-s3-audio-board/config.h`
|
||
|
||
- Added `CONFIG_AUDIO_BOARD_LCD_JD9853_1P47` configuration section
|
||
- Resolution: 172×320 pixels (portrait mode)
|
||
- Display driver: JD9853
|
||
- Touch controller: AXS5106L (I2C address 0x3B)
|
||
- Proper display transformations (swap_xy, mirror_x, mirror_y)
|
||
- Display offset compensation (Y offset: 34 pixels)
|
||
|
||
### 2. Build Variant ✅
|
||
**File:** `xiaozhi-esp32/main/boards/waveshare-s3-audio-board/config.json`
|
||
|
||
- Added new build variant: `waveshare-s3-audio-board-1.47lcd`
|
||
- Includes all camera configurations (OV2640/OV5640)
|
||
- WeChat message style enabled
|
||
- All features enabled: audio, camera, touch, RGB LEDs
|
||
|
||
### 3. Touch Controller Integration ✅
|
||
**File:** `xiaozhi-esp32/main/boards/waveshare-s3-audio-board/esp32-s3-audio_board.cc`
|
||
|
||
- Implemented `InitializeTouch()` method using AXS15231B driver (compatible with AXS5106L)
|
||
- I2C-based touch controller initialization
|
||
- LVGL touch integration for UI interaction
|
||
- Touch configuration: 172×320 resolution with proper coordinate mapping
|
||
- Conditional compilation for 1.47" LCD variant only
|
||
|
||
### 4. Dark Mode Support ✅
|
||
**File:** `xiaozhi-esp32/main/boards/waveshare-s3-audio-board/esp32-s3-audio_board.cc`
|
||
|
||
- Implemented `InitializeTools()` method with MCP tools
|
||
- Added `self.display.set_theme` tool for switching themes (light/dark)
|
||
- Added `self.display.get_theme` tool for querying current theme
|
||
- Theme settings persist across reboots
|
||
- Dark mode optimized for 1.47" display viewing
|
||
|
||
### 5. Font Optimization ✅
|
||
**File:** `xiaozhi-esp32/main/CMakeLists.txt`
|
||
|
||
- Conditional font configuration based on LCD variant
|
||
- 1.47" LCD uses smaller fonts: `font_puhui_basic_14_1` and `font_awesome_14_1`
|
||
- Smaller emoji collection: `twemoji_32` (optimized for small screen)
|
||
- Better readability on the 172×320 display
|
||
|
||
### 6. Kconfig Integration ✅
|
||
**File:** `xiaozhi-esp32/main/Kconfig.projbuild`
|
||
|
||
- Added LCD type selection option: "JD9853 1.47inch Touch LCD 172*320 (with AXS5106L touch)"
|
||
- Accessible via menuconfig under `ESP32S3_AUDIO_BOARD LCD Type`
|
||
- Allows easy switching between display variants
|
||
|
||
