Hm - still confused (ok - it's not difficult to confuse me ...)

- You use datapin 6 in your listing which according to the above posted diagramm is the Pin called DAC. The Sparkboard states to use D6 (what I have seen on the pictures) - so wich Pin are you using for Di?
- I have a pixles Ring with ws2812b. The Neopixles one has ws2812. I would have gused that your program works with both versions? Or is ws2812b different?
- Do you know if there is a way to get a Log from the core - I tried it with the several tools (also the setuptool via CMD for windows) to see if it receives anything - but without luck so far. On the MP side there is no log for atmorob?
- In my planless ways of trying to figure out how electric works (i am a mechancal engeneer .. so don't ask me to read how strong a resistor is ) I have seen that in some places Sparkfun speaks about the need to have a resitor bevore Di. but I don't think this is need so direct connection should be fine?

Well - until today I had no luck with any of the units I tried - but I won't give up
