does this need updating to sync up with latest RGBW tweaks?

hmm thats odd - it does work with normal RGB neopixels right?

@ladyada Unfortunately I don't have any RGBs to test. I'll edit issue to add example code and the resulting color sequence here in a sec.

I will add that I did try rpi_ws281x's Python examples, notably SK6812_strandtest.py, which does solid color fills, including white, and that was working as expected.

oh ok you know i know what happened, i can fix it
from adafruit_blinka.
no i think its just the way the raspi neopixel driver expects data, if i set it to RGBW i think i have to shift data in differently. im getting an RGBW ring to do a proper test

I'd be happy to test a fix on my strip when you have one. I prototyped a fix (changed the # assign all colors!
block to also be based on LED_STRIP
and shift the w value out of buf
into pixel
in the RGBW case), but I don't have a way to test anything but that.

i believe its now fixed in a PR
