The title says most of the issue.
I have 300 WS2811s and when I set some animations ( not all ) some of the LEDs flicker from time to time. ( see video ( in slow mo so you can see the flicker )) The LEDs that flicker are not always the same and it does not matter the brightness level I have the LEDs set to the flickering just gets more dim or bright depending on the brightness level.
I am quite experienced with WLED so have tried all the usual tricks, there is a level shifter on the data line with a 68Ohm resistor in line. I have tried multiple controllers, including an of the self one I had lying around.
It has a 12v 10A power supply and I have set the output limit at 2A, Currently it is running of an ESP32 C3. I have not run power injection as the wife factor may go down if I have extra wires in places but that is the last thing on my list to try.
Any suggestions or advices would be greatly appreciated.
. I have tried another smaller power supply to the same result. And no resistor on data, still the same. I’m now thinking it may be a dodgy pixel. Corrupting the data at some point. But tracking that down on a line of 300 sounds quite painful.
