Hi everyone,

I’m working on a project using the Rubik Pi 3 and I’m running into an intermittent issue where my LCD sometimes displays garbled characters instead of the intended data. I have checked the wiring and don’t think it is the cause of this problem.

Any suggestions on how to resolve this would be greatly appreciated!

My Setup:

  • Board: Rubik Pi 3 V02
  • Interface: UART at 115200 baud
  • Driver: Driving the bus with a Python script
  • LCD Display: NHD-0216BZ-RN-YBW (running on 5V supply)

Do you mean that the serial data displayed on the LCD is occasionally garbled? Could you please clarify whether you connect the Rubik Pi to the LCD via a Micro-USB cable or jumper wires?
We recommend you start troubleshooting from the perspective of ground connection.

Resolved it by strengthening the wire connections. Thank you!
