setup:
I have an Arduino MKR Zero controlling 2 sets of led strips, both 12V
both sets of strips have positive tied together to 12V PSU
both sets of strips have ground tied together along with board ground and PSU ground
first set of strip is 8 * 50 WS2811, christmas lights individually addressable
second set is 4 * 100, stick strip group of 3 addressable (300 leds with 100 controls each strip)
First set of strips works completely fine for all 8 strips in daisy chain
Listing the first set even though there's no problem to demonstrate there's no issue with code/power
problem:
Second set of strips only works for first strip, the second strip doesn't light up properly. If I repeated unplug and replug, the first LED for the second strip sometimes comes on as solid blue, sometimes the whole strip flicker but dims after (so pos and ground must be good, check with meter and ~12V). The data arrows are going along same direction across the connection. Tried swapping the first and second strips a couple times but that didn't fix it (so I don't think it's bad strips, and it's the same brand as the other set that works correctly), so what am I doing wrong?
