Getting to grips with FastLED but one thing that’s puzzling me is what hue is 0 meant to be? Most sites seem to suggest it’s red (wikipedia, the FastLED chart on the wiki…) but fill_solid( &(leds[0]), 100 , CHSV( 0, 255, 255) ) gives a wall of green…?
Have you tested to verify you have the correct RGB order when you declare your strips? https://github.com/FastLED/FastLED/wiki/Rgb-calibration
You may need to calibrate your led strips (check the examples directory) because not all strips are rgb ordered. For example, mine are grb, which means trying to write solid red will write green instead
D’oh. I read that in the instructions and disregarded it (neopixels must be RGB, right?? Wrong…). They were GRB. Thanks!
