Mapping itself is really easy, since it’s just a ring, as you said… The radius changes as it gets bigger, but the angles remain the same since the number of LEDs is constant each ring.
I know there is mapping code I wrote that you plug in the number of rings and count for each and that would work fine… EXCEPT in this case, you aren’t going around and then onto the next ring, you are doing a strip, and going on to the next strip, so that ring code won’t work as written, but it’s a simple change to iterate the angle then the radius(es) (radii?) Rather than the way that code goes now.
I’ll post a version that will work for you when I get a chance to rewrite the above linked code.
Ah, just noticed some strips have less LEDs than others… Yeah, that’ll have to be handled too.
Likely it’ll be stripcount instead of ringcount, since the number of LEDs varies per strip…
Just to get the map sizing right, relative to the space between LEDs (so between two on a strip), how big is the space from center of the hex to the first LED on the strip? Please post both measurements. (I can guess at the space between but confirmation is good), also which is strip 1 and strip 2, (clockwise or counterclockwise?)
