This repository provides code examples, documentation, and community support to help you get started with your projects.

5. Funcionament del Consell

5.1 Funcionament bàsic

• Encès/apagat: Use the physical power switch to turn the board on or off.
• Botó de restabliment: Press the "RST" button to perform a hardware reset of the ESP32-S3 module.
• Botó d'arrencada: The "Boot" button is typically used to put the ESP32-S3 into bootloader mode for flashing new firmware. Hold down the "Boot" button, press and release "RST", then release "Boot".

5.2 Programming and Uploading

Once your development environment is set up, you can write and upload your code to the T7-S3 board. The process generally involves:

1. Writing your C/C++ or MicroPython code.
2. Selecting the correct board model (ESP32-S3 Dev Module) and COM port in your IDE.
3. Compiling and uploading the code to the board. The IDE will typically handle putting the board into flashing mode automatically, or you may need to manually use the Boot button as described above.

6. Manteniment

To ensure the longevity and optimal performance of your LILYGO T7-S3 Development Board, follow these maintenance guidelines:

• Manejar amb cura: Avoid dropping the board or subjecting it to physical shock.
• Electricitat estàtica: Always handle the board in an anti-static environment or take precautions to discharge static electricity before touching it.
• Neteja: Keep the board free from dust, dirt, and moisture. Use a soft, dry brush or compressed air to clean it if necessary. Do not use liquids or solvents.
• Emmagatzematge: When not in use, store the board in an anti-static bag or a protective enclosure to prevent damage.
• Font d'alimentació: Use only appropriate power sources (e.g., 5V via USB-C) to avoid damaging the board.

7. Solució De Problemes

If you encounter issues with your LILYGO T7-S3 board, consider the following troubleshooting steps:

• Board Not Detected by Computer:
  • Ensure the USB-C cable is securely connected to both the board and your computer.
