So I narrowed down the source of my problem. It seems that whenever i have the LCD Panel (Viki 2) plugged into the board, it starts giving off the error. the instant I unplug it, the error stops. Any ideas what might be causing this?
Those drivers use SPI… so that might be conflicting.
Hmm. I’ll have to go through the config and see if there is a pin that is conflicting. Might try a different firmware as well just to make sure it’s not that either
Im not too familiar with the SPI drivers, but I cant find any conflicts with the pins. What else could be wrong?
Shield your cables to the panel and ground one end
