Generic WiFi R3 ATmega328P+ESP8266 Development Board User Manual

1. Pengenalan

This manual provides instructions for the Generic WiFi R3 ATmega328P+ESP8266 Development Board. This board integrates an Uno R3 ATmega328 microcontroller and an ESP8266 WiFi module with 32Mb memory onto a single platform. It is designed for projects requiring both microcontroller and WiFi capabilities, offering flexibility for various applications. The board features a USB-serial converter (CH340G) for updating sketches and firmware for both the ATmega328 and ESP8266.

The integrated DIP switch allows for flexible configuration, enabling the modules to work together or independently, and facilitating communication between the USB interface and each module.

3.1 Tetapan Suis DIP

Refer to the table below for the correct DIP switch settings for various operational modes. "ON" indicates the switch is in the ON position, and "OFF" indicates the switch is in the OFF position.

Penting: Always ensure the correct DIP switch settings are applied before powering on the board or attempting to upload sketches/firmware. Incorrect settings can lead to communication errors or unexpected behavior.

4. Arahan Operasi

4.1 Menguasakan Lembaga

The board can be powered via the USB port or an external DC power supply (7-12V). Ensure the power source meets the board's requirements.

4.2 Programming the ATmega328 (Arduino Uno R3)

1. Set the DIP switches for USB <-> ATmega328 communication (OFF, OFF, ON, ON, OFF, OFF, OFF).
2. Sambungkan papan ke komputer anda menggunakan kabel USB.
3. Buka Arduino IDE.
4. Select the correct board (Arduino Uno) and COM port from the Tools menu.
5. Upload your sketch to the ATmega328.

4.3 Programming the ESP8266 (NodeMCU/WeMos)

1. Set the DIP switches for USB <-> ESP8266 (Update firmware/sketch) (OFF, OFF, OFF, OFF, ON, ON, ON).
2. Connect the board to your computer via USB.
3. Use the appropriate IDE (e.g., Arduino IDE with ESP8266 board manager, or NodeMCU firmware flashing tools) to upload your code or firmware.
4. After uploading, you may switch to USB <-> ESP8266 (Communication) (OFF, OFF, OFF, OFF, ON, ON, OFF) for serial communication with the ESP8266.

4.4 ATmega328 and ESP8266 Intercommunication

To enable communication between the ATmega328 and ESP8266 modules on the board:

1. Set the DIP switches for ATmega328 <-> ESP8266 (ON, ON, OFF, OFF, OFF, OFF, OFF).
2. Ensure both modules are correctly programmed to communicate with each other via their respective serial pins.

5. Penyelenggaraan

• Pembersihan: Gunakan kain lembut dan kering untuk membersihkan papan. Elakkan menggunakan cecair atau pembersih yang kasar.
• Storan: Simpan papan di persekitaran yang kering dan anti-statik apabila tidak digunakan.
• Pengendalian: Handle the board by its edges to avoid touching components, especially when powered. Static electricity can damage sensitive components.
• Kemas kini Firmware: Regularly check for updated firmware for the ESP8266 module and drivers for the CH340G USB-serial converter to ensure optimal performance and compatibility.

6. Penyelesaian masalah

• Papan Tidak Dikesan oleh Komputer:
  • Pastikan kabel USB disambungkan dengan selamat.
  • Verify that the CH340G USB-serial driver is installed on your computer. Drivers are typically available from the manufacturer's website or common online resources.
  • Check DIP switch settings for USB communication (e.g., USB <-> ATmega328 or USB <-> ESP8266).
• Sketch/Firmware Upload Failure:
  • Confirm the correct DIP switch settings for programming the target module (ATmega328 or ESP8266).
  • Ensure the correct board type and COM port are selected in your IDE.
  • Check for any error messages in the IDE output for specific guidance.
• Isu Kesambungan WiFi:
  • Verify the ESP8266 firmware is correctly installed and configured for WiFi.
  • Ensure the ESP8266 has sufficient power.
  • Check the WiFi network credentials in your code.
• Inter-module Communication Problems (ATmega328 <-> ESP8266):
  • Confirm DIP switches are set for ATmega328 <-> ESP8266 communication.
  • Verify that both modules are programmed to communicate using the correct serial protocols and baud rates.
