why doesn’t this work?

on the same strip of leds, is it because the code is writing to the same leds. in the test code, i am writing to one section ONLY… as in, i have the BLOCKb[0] bit in the code, but not using it anywhere, and only calling the leds code at the moment.

i would have guessed that if i have 2 arrays setup, using the same leds and calling them at the same time, this may have caused issues…

FastLED.addLeds<WS2812B, DATA_PIN, BRG>(leds, NUM_LEDS);

FastLED.addLeds<WS2812B, DATA_PIN, BRG>(BLOCKb[0], 0*NUM_LEDS_IN_SEGMENT, NUM_SIDES);

easy to get past, but annoying for future thoughts.

You can’t call addLeds twice on the same pin - it won’t do anything that you’re expecting it to do, so don’t do it.

(if I had a way to have that cause an error at compile time, I would)

ahh, i read the different pin allocations, but was reading (incorrectly) through the lines, and had a few allocations to the same pin.

whilst it was lighting some leds, it wasnt trashing the code, just not working right! :: LOL ::

in fact, that little niggle of information has chosen the direction of the code going forward! thanks! :slight_smile:
