I currently have an Arduino Uno attached via i2c to Qwiic connector on the GPS-RTK2 Zed9 board. Then I also have an additional Qwiic connector running from the GPS board to a 20x4 SerLCD.
Like this setup https://learn.sparkfun.com/tutorials/gp … ion-source.
I am trying to run the Spark Fun Arduino Example
https://github.com/sparkfun/SparkFun_Ub … ithLCD.ino
However, It is not displaying on the LCD. I have also noticed that the code only runs when the Arduino is connected to a certain qwiic connector on the GPS board. Has anyone had this problem before or know how to get the LCD display to work?
