3. คู่มือการใช้งาน

Once the board is set up with your preferred development environment, you can begin programming and utilizing its features.

3.1 Programming and Uploading Code

1. Write Code: Develop your application code using C/C++ (ESP-IDF, Arduino) or Python (MicroPython).
2. รวบรวม: Compile your code within your chosen IDE or framework.
3. เชื่อมต่อ: Ensure the board is correctly connected to your computer via the adapter board and USB cable.
4. อัพโหลด: Use the upload function in your IDE to flash the compiled firmware onto the ESP32-S3 board. You may need to press the BOOT button on the adapter board while pressing and releasing the RESET button to enter download mode, depending on your setup and software configuration.

3.2 Utilizing GPIO Pins

The 34 multi-function GPIO pins can be configured for various purposes, including digital input/output, analog-to-digital conversion (ADC), pulse-width modulation (PWM), and communication protocols like SPI, I2C, and UART.

• Refer to the pinout diagram (Image 3.1) and the ESP32-S3 datasheet for detailed information on each pin's capabilities.
• Use the respective libraries and functions in your chosen SDK (e.g., `digitalWrite()`, `analogRead()` in Arduino) to interact with the GPIOs.
