5. ຕັ້ງຄ່າ
Follow these steps to set up your Waveshare ESP32-S3-Nano-M Development Board:
- ຕິດຕັ້ງ Arduino IDE: ດາວໂຫຼດ ແລະ ຕິດຕັ້ງ Arduino IDE ລຸ້ນລ່າສຸດຈາກ Arduino ຢ່າງເປັນທາງການ webເວັບໄຊ (www.arduino.cc/en/software).
- Add ESP32 Board Support:
- ເປີດ Arduino IDE, ໄປທີ່ File > ຄວາມມັກ.
- In the 'Additional Boards Manager URLs' field, add the ESP32 board manager URL (ໂດຍປົກກະຕິ
https://raw.githubusercontent.com/espressif/arduino-esp32/gh-pages/package_esp32_index.json). - ໄປທີ່ ເຄື່ອງມື > ກະດານ > ຜູ້ຈັດການກະດານ.... ຊອກຫາ 'ESP32' and install the 'esp32 by Espressif Systems' package.
- ເລືອກກະດານ: ຫຼັງຈາກຕິດຕັ້ງແລ້ວ, ໃຫ້ໄປທີ່ 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).
- ເຊື່ອມຕໍ່ກະດານ: Connect the ESP32-S3-Nano-M to your computer using a USB Type-C cable.
- ເລືອກຜອດ: ໃນ Arduino IDE, ໄປທີ່ ເຄື່ອງມື > ພອດ and select the serial port corresponding to your connected ESP32 board.
- ຕິດຕັ້ງໄດເວີ (ຖ້າຈໍາເປັນ): 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. ຄໍາແນະນໍາການດໍາເນີນງານ
Once the board is set up, you can begin programming and operating it:

- 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.
- 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 webເວັບໄຊ (micropython.org/download/esp32s3/).
