Lessons learned. After doubting my wiring, my code, my power supply, my design, and my sanity, I finally traced the intermittent issue I was having with my 2nd 64 x 64 matrix to a bad Teensy 3.2 OctoWS2811 Adaptor. So, the lesson is trust nothing and start by swapping out the easy stuff first. This could have been solved long before it was.

3 steps in trouble shooting… divide in half. Look left signals good, step right and repeat… :slight_smile:

@Mark_Estes oh my, sorry to hear this. Now, do you even need the OctoWS2811? Can’t you wire 16 or even 24 lines to a teensy directly without it?
