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. Mantenimiento

• Limpieza: Use a soft, dry cloth to clean the module and display. Avoid liquid cleaners directly on the board.
• Almacenamiento: Guarde el módulo en un entorno seco y antiestático cuando no esté en uso.
• Manejo: Avoid applying excessive force to the display or connectors. Handle the board by its edges to prevent damage to components.
• Actualizaciones de firmware: Regularly check the official GitHub repository for firmware updates and bug fixes to ensure optimal performance.

7. Solución de problemas

• El módulo no se enciende:
  • Ensure the USB-C cable is securely connected and providing power.
  • If using a battery, check that it is charged and correctly connected to the JST port.
• La pantalla no funciona:
  • Verify that your code initializes the ST7789V display correctly.
  • Verifique si hay daños físicos en la pantalla o sus conexiones.
• Errores de carga:
  • 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.
• Problemas de Wi-Fi/Bluetooth:
  • Verifique su código para verificar que la inicialización y las credenciales de Wi-Fi/Bluetooth sean correctas.
  • Ensure sufficient power supply for wireless operations.
