Hey there, i recently bought a 16x32 RGB LED panel from adafruit for a project. with the tutorial and libraries posted I had it up and running in like 30 minutes (excellent btw!)
However, several days later after I was working on some of my own code to run on the panel, everything seemed to die. It was working fine, then the next time I uploaded code everything just seemed to go awry.
First every other row of the panel was not lighting up, but if I fiddled with the crimp connector between my breadboard and the arduino, the rows that were off would come back on a bit, though still not the right colors or consistently. I figured maybe something was wrong with that so I recrimped the wires and retried.
The problem seemed to manifest itself differently with the pixels on the rows being offset from where they should be. I rebuilt the circuit entirely and with a new arduino and the same problem existed.
I am wondering if there is something wrong with the controller itself at this point?
Any suggestions for further troubleshooting? also do you happen to have a schematic of the circuit so I can try to isolate where the problem is exactly?
Any other suggestions on what I could try? I'm wondering at this
edit- just to make it clear, I am still using an unchanged version of the adafruit libraries used to run things, and running the basic built-in examples to test.
