5. Орнотуу
5.1 Алгачкы зымдар
- Электр камсыздоо: Connect the 3V3 pin to a stable 3.3V power source and GND to ground. Ensure your power supply can provide sufficient current (typically 500mA or more for ESP32 modules, especially during WiFi/Bluetooth operations).
- Сериялык байланыш: For programming and debugging, connect TXD0 to the RX pin of your USB-to-Serial converter (or development board's RX) and RXD0 to the TX pin of your converter (or development board's TX). Ensure the converter operates at 3.3V logic levels.
- Enable Pin: The EN pin is usually pulled high internally. To reset the module, pull this pin low momentarily.
- Жүктөө режими: For flashing new firmware, GPIO0 typically needs to be pulled low during reset. Consult your specific development environment's documentation for the exact boot sequence.
5.2 Программалык камсыздоону орнотуу
The XH-32S module can be programmed using various development environments, including the Arduino IDE with ESP32 board support, or the Espressif IoT Development Framework (ESP-IDF).
- Драйверлерди орнотуу: If using a USB-to-Serial converter, install the necessary drivers for your operating system.
- IDE орнотуулары: Follow the official Espressif documentation or community guides to set up your chosen IDE for ESP32 development. This typically involves installing board definitions and libraries.
