Phase 2: I have managed to have the ESP32 and the Jinx working fine on a 10x10 panel. I am using a 10x10 panel because I have noticed that when I configure the ArtNet output device on Jinx, it locks in 512 channels. That was expected, because one DMX universe has 512 channels. My 10x20 panel has 200 LEDs which means 600 channels. I will work on the universes to see if I can have my 10x20 panel fully working too with ESP32 and Jinx.
Once I have it working, I will try to use the Resolume Arena with my ESP32.
