Dear all,
Recently I installed 2 WS2812b ledstrips (60leds/meter) behind my television to simulate some sort of amiblight. Each led string consists of 120 LEDS and both strings were cut from the same 5m strip.
I use a 5V 20A power supply to power the leds. Each strip has the +5V lead soldered on the beginning of each strip as well as the ground connection.
The ledstrips are controlled through a Teensy 3.2 and octoWS2811 combo. As I have only two strips, only 2 out of 8 possible channels are used.
I used the standard code on the teensy: https://github.com/PaulStoffregen/OctoWS2811/blob/master/examples/Adalight/Adalight.ino
The adalight is fed through a program called hyperion [https://github.com/hyperion-project/hyperion/wiki] which runs on my pi2.
This setup has been working flawlessly for 1/2 year; but now one of the two strips starts flickering and shows wrong coloring.
This does not happen all the time and seems random. I checked every connection on the strip and resoldered every wire; but this did not solve the problem.
The strange thing is that the other led strip is doing fine and works perfectly. The strips are being driven by the same Power Supply; so I don't think this is the problem. The output of my Power Supply is about 5.25 volt, and I don't have a massive voltage drop at the end of the strip. The voltage values seem good.
I use thick wiring for the ground and +5V leads, but the signal lead is quite thin, as is the case in a normal cat6e network cable, which I use to carry the signal lead.
What could be causing these issues?
Many thanks for any help.
