Hello,
I have a fully working Hyperion Ambilight setup, however when there is a bright image on screen, or the remote app is used to put the LEDs at 100% white, there is lots of flicker/flashing of the whole strip of 312 LEDs as if suddenly hit with lots of interference.
At first I thought this might be a power supply / voltage drop issue, but a quick test with the Adafruit strand test and an Arduino is rock solid at 100% white (same power supply, just moving data and ground pins from RPi to Arduino [grounds are commoned]).
I think this proves there is nothing wrong with the power supply, wiring, LEDs or hardware, but something within the RPi or Hyperion is causing this. Any ideas? @penfold42
Many thanks,
Warren
