It doesn't necessarily have to be Arduino. I have ESP8266's, ESP32's, STM32's TM4C1294's, and RTL8710's in my collection.
I am trying to troubleshoot the pixel-installation-from-hell and trying to build a portable tester-analyzer for locations I can't easily bring the laptop (ie: steep roof). My logic analyzer captures the signal, but won't decode it, I have to do that 'by hand' which is a pain, and again, I can't easily carry the laptop to the problem.
I don't have time to write something from scratch, and not sure my coding skills are quite to that level anyway. I need to resolve this pixel problem ASAP.
