RGBW neopixel leds

Fri 2019.02.08

Thank you @AkosLukacs for the source and image from #4 above.

@Spocki thanks for the trio variant summary: RGBNW (natural white), RGBCW (cold white) and RGBWW (warm white)

AkosLukacs, how did you determine that quad Uint's were needed, as the BangGood page specifies RGB+White and also indicates (while incorrect) WS2812 (tripplet Uint's), which you (array divide by three) have proven can't be - see what follows. If a S.W.A.G.'d guess, then it appears you may have gotten lucky there, even though you were led to believe you received WS2812

Did anyone else observe the inconsistency?


From image in #4 the output as explained is from right to left: (reversed here)

Green : Red : Blue : Yellowish White : Bright White : RGB White

Spec sheet SK6812 shows RGBW   which can't possibly be


as we have #4:

[50,0,0,0, 0,50,0,0, 0,0,50,0, 0,0,0,50, 50,50,50,50, 50,50,50,0]
   G R B W   G R B W   G R B W   G R B W   

Can't be these either ref: RGB WS2811 or BGR APA102

So, do we have yet another mis-represented Asian knockoff, or a spec sheet that is incorrect and we now need to search for yet another variant to contend with?
