Led: WS2801 (32+15 leds)
Power Supply: 3A 5V
RPI 2
I had flickering problem, but it was solved by soldering all wires. External 5v connected to RPI GND.
So here is my problem:
I set red, all leds are red - then 1 sec later, this led changes his color to opposite
If blue - it became red and etc.
I noticed, that if I use half brightness, led stays in correct color.
All other leds look stable, but this one flashes quickly with different colors.
