Till now I tested all the routines and nothing running beside that.
I will test the various codes & options in larger programs with other time & interrupt critical routines and give some feedback on performance.
The color sequence vs array pos. I stated for those interested in coding/addressing the ledarr() in such way that only led position and color is needed (maybe with overlays and such).
For that matter, it is the same sequence in both the "ASM NOP snake" and the DMA based code.
