5. Betjeningsvejledning

5.1 Softwareudvikling

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 detaljerede programmeringsvejledninger, f.eks.amples, and libraries, refer to the official LILYGO GitHub repository:

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. Vedligeholdelse

• Rensning: Use a soft, dry cloth to clean the module and display. Avoid liquid cleaners directly on the board.
• Opbevaring: Opbevar modulet i et tørt, antistatisk miljø, når det ikke er i brug.
• Håndtering: Undgå at bruge for meget kraft på skærmen eller stikkene. Hold fast i kortet i kanterne for at forhindre beskadigelse af komponenterne.
• Firmwareopdateringer: Regularly check the official GitHub repository for firmware updates and bug fixes to ensure optimal performance.

7. Fejlfinding

• Modulet tændes ikke:
  • Sørg for, at USB-C-kablet er tilsluttet korrekt og leverer strøm.
  • If using a battery, check that it is charged and correctly connected to the JST port.
• Skærm virker ikke:
  • Verify that your code initializes the ST7789V display correctly.
  • Kontroller for fysisk skade på skærmen eller dens forbindelser.
• Uploadfejl:
  • 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.
• Wi-Fi/Bluetooth-problemer:
  • Kontrollér din kode for korrekt Wi-Fi/Bluetooth-initialisering og legitimationsoplysninger.
  • Ensure sufficient power supply for wireless operations.
