5. Configuración

Follow these steps to set up your Waveshare ESP32-S3-Nano-M Development Board:

1. Instalar o IDE de Arduino: Descarga e instala a última versión do IDE de Arduino desde a páxina oficial de Arduino. websitio (www.arduino.cc/en/software).
2. Add ESP32 Board Support:
   • Abre o IDE de Arduino e vai a File > Preferencias.
   • In the 'Additional Boards Manager URLs' field, add the ESP32 board manager URL (normalmente https://raw.githubusercontent.com/espressif/arduino-esp32/gh-pages/package_esp32_index.json).
   • Ir a Ferramentas > Taboleiro > Xestor de taboleiros.... Busca 'ESP32' and install the 'esp32 by Espressif Systems' package.
3. Select Board: After installation, go to Tools > Board > ESP32 Arduino and select the appropriate board for ESP32-S3 (e.g., 'ESP32S3 Dev Module' or similar, depending on the installed package version).
4. Conecta a placa: Connect the ESP32-S3-Nano-M to your computer using a USB Type-C cable.
5. Seleccione o porto: No IDE de Arduino, vai a Ferramentas > Porto and select the serial port corresponding to your connected ESP32 board.
6. Instalar controladores (se é necesario): On some operating systems, you may need to install USB-to-serial drivers (e.g., CP210x or CH340/CH341) if the board is not recognized.

6. Instrucións de funcionamento

Once the board is set up, you can begin programming and operating it:

1. Programming with Arduino IDE:
   • Abre un example sketch (File > Examples) or write your own code.
   • Click the 'Verify' button (checkmark icon) to compile your code.
   • Click the 'Upload' button (right arrow icon) to upload the compiled code to your ESP32-S3-Nano-M board. Ensure the correct board and port are selected.
   • Monitor serial output using the Serial Monitor (Tools > Serial Monitor) to debug or view program output.
2. Programming with MicroPython:
   • Install esptool.py: pip install esptool.
   • Erase flash: esptool.py --chip esp32s3 erase_flash.
   • Download the latest MicroPython firmware for ESP32-S3 from the official MicroPython websitio (micropython.org/download/esp32s3/).
   • Flash firmware: esptool.py --chip esp32s3 --port [YOUR_PORT] write_flash -z 0x0 [FIRMWARE_FILE.bin]. Replace [YOUR_PORT] with your board's serial port and [FIRMWARE_FILE.bin] with the downloaded firmware file.
   • Use a tool like Thonny IDE to connect to the board and write/upload MicroPython scripts.
3. Using Arduino IoT Cloud:
   • Crea unha conta na nube Arduino IoT websitio (create.arduino.cc/iot/).
   • Follow the on-screen instructions to register your ESP32-S3-Nano-M board as a new device.
   • Develop dashboards and integrate your board with cloud services for remote monitoring and control.

7 Solución de problemas

If you encounter issues with your ESP32-S3-Nano-M board, consider the following troubleshooting steps:

• Placa non detectada: Ensure the USB Type-C cable is fully inserted and functional. Try a different USB port or cable. Verify that the necessary USB-to-serial drivers are installed on your computer.
• Erros de subida: Check that the correct board type and serial port are selected in the Arduino IDE. Sometimes, pressing and holding the 'BOOT' button while pressing 'RST' (then releasing 'RST' and then 'BOOT') can put the ESP32 into bootloader mode for successful flashing.
• Code Not Running: After uploading, press the 'RST' button on the board to restart the program. Check your code for logical errors using the Serial Monitor.
• Problemas de conectividade Wi-Fi/Bluetooth: Ensure your network credentials are correct in your code. Check for interference from other 2.4GHz devices. Verify antenna integrity.
• Problemas de enerxía: Ensure the power supply is within the specified 6-21V range. If using external power, ensure connections are secure and polarity is correct.
