5. Hướng dẫn vận hành
5.1 Software Development
The LILYGO T-Display ESP32 module can be programmed using popular development environments:
- Arduino IDE: Install the ESP32 board support package in the Arduino IDE. Select the appropriate board (e.g., ESP32 Dev Module) and port.
- MicroPython: Flash MicroPython firmware to the ESP32, then use a serial terminal or IDE like Thonny to upload scripts.
For detailed programming guides, examples, and libraries, refer to the official LILYGO GitHub repository:
github.com/Xinyuan-LilyGO/TTGO-T-Display
5.2 Using the Display and Buttons
The 1.14-inch IPS display is controlled via SPI. Libraries are available for graphics and text display. The two onboard buttons (GPIO0 and GPIO35) can be programmed for user input, menu navigation, or other functions within your application.
6. Bảo trì
- Vệ sinh: Use a soft, dry cloth to clean the module and display. Avoid liquid cleaners directly on the board.
- Kho: Store the module in a dry, anti-static environment when not in use.
- Xử lý: Avoid applying excessive force to the display or connectors. Handle the board by its edges to prevent damage to components.
- Cập nhật chương trình cơ sở: Regularly check the official GitHub repository for firmware updates and bug fixes to ensure optimal performance.
KHAI THÁC. Xử lý sự cố
- Mô-đun không bật nguồn:
- Hãy đảm bảo cáp USB-C được kết nối chắc chắn và đang cung cấp nguồn điện.
- If using a battery, check that it is charged and correctly connected to the JST port.
- Hiển thị không hoạt động:
- Verify that your code initializes the ST7789V display correctly.
- Check for any physical damage to the display or its connections.
- Lỗi khi tải lên:
- Ensure the correct board and COM port are selected in your IDE.
- Install the necessary USB-to-serial drivers (CH9102F).
- Sometimes pressing the boot button (if available) while uploading can help.
- Các vấn đề về Wi-Fi/Bluetooth:
- Check your code for correct Wi-Fi/Bluetooth initialization and credentials.
- Ensure sufficient power supply for wireless operations.
