Crazy idea, but what about supporting the inversion of data/clock lines to allow people to use existing, analog LED controllers to run addressable LEDs with existing hardware without modification?
I am planning to add the feature of runtime selectable pins very soon 
So the output pin mapping of nearly all controllers will then work without recompilation or hardware modification!
Thanks. To be clear, I mean an inversion of the outputs (1=0 and 0=1). 
Ahh ok. Should be possible as well: https://github.com/Makuna/NeoPixelBus/issues/174
I suspect my WS2812 strip does not work with the 3.3V data line and needs a level shifter. I’d like to use a simple transistor for this and would need the esp32 signal inverted. I dont see how I use this with WLED. Is this configurable? Compiletime option? Modify code?
Thanks for any hint
