Update, NUM6 fixed the problem! Adding a 1kohm resistor seemed to fix all the problems. But I will still post a more detailed answer to the problem. Hopefully it will help others.
- Yes. That is what happens. Here is a video of this occurring.
- This is a 128x64 display
- The part num is GDM12864HLCM from SparkFun
- The library has not been altered for the Uno. However manual pins were set for the Mega as one of the ports on that controller was found to be bad.
- The two green wires go to a 10k potentiometer. Which is read by A5.
- There was nothing previously. CONNECTING THE RESET PIN TO VCC WITH A RESISTOR SOLVES THE ISSUES
- The number of wires attached does not effect the display performance. The test in 1) was done using the setup from 7).
--Thanks for helping me figure this out Bill!
