Ring 1D 2D QR code scanner
1Platform.Technologies 2023-10-03 04:08:14 276 Views4 Replies I bought Ring 1D 2D QR code scanner and connected to Arduino using I2C communication, also installed the DFRobot_GM60 Library but the scanner doesn't work. I tried UART communication as well but no luck. So, I uploaded the examples provided by the library detect_i2c and detect_uart, both weren't working. 3 months ago I had the same kind of QR code working perfectly fine and never looked into it but all of sudden when I tried to scan it wasn't scanning, I thought scanner gone bad so, I bought the new one and to my surprise same problem. Any help would be greatly appreciated. Thank you.
Have you checked the Arduino board separately? There may be some problems with its I2C pins.
lia.ifat Hello there,
I have the same problem, ¿Did you find a solution?
Regards.
ElectroNIKO Hi, there is an I2C/UART switch on the board. Are you double-checking that turn the DIP switch of the adapter board to I2C and then burn the I2C code?
Afra Hi, Thank you for the reply, yes, I was checking the switch and making sure that it is on the I2C. Even tried on UART side and uploaded the UART code but no luck. Thank you.
