|---|---|---|
| Board not recognized by computer / "I can't get it to work." | Missing or incorrect CH340 driver. Faulty USB cable or port. | Install the correct CH340 driver for your operating system. Try a different USB cable or port. Ensure the board is properly connected. |
| La càrrega del firmware ha fallat. | Board not in firmware download mode. Incorrect COM port or board settings in IDE. | Manteniu premut el botó BOOT button, then plug in the USB cable, release BOOT, and try uploading again. Verify COM port and board settings in Ard-IDE (e.g., "ESP32 Wrover Module", correct COM port, upload speed). |
| LCD display is blank or shows incorrect output. | Incorrect code uploaded. Display initialization issues. | Ensure the correct LCD routine is uploaded. Double-check wiring if using external display (not applicable for integrated). Verify display parameters in code match the board's LCD. |
| Problemes de connexió Wi-Fi. | Incorrect Wi-Fi credentials in code. Weak signal. | Verify Wi-Fi SSID and password in your sketch. Ensure the board is within range of your Wi-Fi router. |
7. Consells d'usuari
- Always ensure the correct drivers (e.g., CH340) are installed on your computer before connecting the board to avoid recognition issues.
- When encountering upload problems, remember the
