【LCSC·ColorEasyDuino Development Board】FAQ
1. Issues with Development Board Recognition
The development board uses the CH340 USB-to-serial converter for program downloading and communication. If the recognition is not successful, it means that the CH340 driver is not installed correctly.Link for driver download: https://www.wch.cn/download/CH341SER_EXE.html You can install it directly after the download is completed.
2. Common Errors in IDE
- “avrdude: stk500_getsync(): not in sync: resp=0x00”
The response resp=0x00 is a general error indicating that the ATmega chip on the Arduino board is not functioning. When this happens, there are several solutions:
a. Ensure that there are no connections to digital pins 0 and 1 on the Arduino (including any shields).
b. Make sure you have selected the correct COM port and board in the Tools menu.
c. Press the reset button on the Arduino a few times and then try to upload the code again.
d. Disconnect and reconnect the Arduino to the PC.
e. Restart the Arduino IDE.
f. The bootloader on the board may be corrupted, requiring you to reprogram the Arduino firmware.
- Invalid Device Signature
If you encounter an error while uploading code to the development board, it’s likely because the correct board is not selected in the IDE. This error usually occurs when the device signature on the development board does not match the board selected in the IDE. Please make sure to select the correct option shown in the image below:
