8x8 neopixel panel not lighting properly

by T3chn0h1ppy on Sun Apr 15, 2018 1:31 pm

Hi There,

Very new to neopixels and struggling to figure out where I start troubleshooting this. I have a fadecandy and an 8x8 neopixel panel and I've been following Micah scotts excellent tutorial for this very set up. I have everything wired up and have used the local host connection page to test the leds. The problem I have is that two rows of pixels are not lighting up, I can get the 50% brightness and full brightness to work on all but the two rows.

I have opened up the processing examples for this grid with the same problem, two rows not lighting up and the rest not behaving as they should, presumably because the two rows are missing.

Any guidance you have would be greatly appreciated.
