Anyone had a situation when a ws2812b strip has random pixels “flicker”? I’ve tried it with a Mega and Due with FastLED. I’ve also tried using screened cable for I/O. Any other suggestions?

Thanks

How many pixels? I will run into this issue when I’m running out of power. maybe try injecting power from both ends.

Also - how long is the cable from your controller to the strips? Also, also - how close to 5v is your power? I go back and forth on there being either a timing problem or a problem when something with a 3.3v output (the due) talks to something running at 5.2 vs 5v.

Hi - 288 pixels (2m strip). Power cable about 1m run (from 40A transformer to first LED).

Thanks
