Trying to get Started

[utemorley2012]

Hi All,

Pretty new to Matrix LED Panels and Raspberry Pi but I am attempting to build my own sports ticker. I have 5 128x64 modules I am trying to set in parallel with a raspberry pi 4. I have followed all of the tutorials in the READMEs but just can't seem to get the panels to do anything really. I have checked the wiring (regular mapping) again and again and am wondering if there is a way to just test to see if the panels are working. I only have 1 connected right now and confirmed it is receiving 5.15 V. Here is an image of my panels.

I have tried lots of different demo code option combos (too many to list here) and still nothing. Any ideas? Thanks so much!
