ey mcnobby!
I am trying out your amazing code, and it is working nicely, but there are 2 weirds things going on:
The first pixel is always displaying some degree of green, regardless what I send there is always a little bit of green. I tried different strips and I always get the same result.
Also, specially in the first pixel but not exclusively, there is some flickering. I trid with and without a 470Ohm resistor and it flickers both ways.
I copy the code as I am using it here:
/*
SmartShow AirPixel ONE - Single Universe ArtNet to WS2812 Driver - For Wemos D1
You can set the Device IP, and universe number below
Works perfectly with Jinx LED software

Did you already posted the project that handles 32 universes?
Also, is there no way to control the rgb order in the sketch right? The order is not correct as we speak.
Thank you so much for this!
