Hello all,
I've been following this forum for a while and have been on this Ambilight project for several weeks. I am finally resorting to creating my own topic here. I'm using RPI 3B+ and LibreElec 8.2.4 with about 100 APA102 LEDs. I also have some 74HCT08 chips for a level shifter.
Please skip this background if you're only interested in helping my immediate problem:
Background:
[INDENT]I spent my first weekend with allnighters and had it finally found it working randomly when i came home from a day out.
The lights worked perfectly for a week. Then, while sending a new config file when trying to color correct for my blue painted wall, the software stopped working entirely. I believe somehow all the memory available was used up and hyperion said it could not even store screenshots anymore.
I decided to do a fresh install of everything since I needed to permanently fix everything anyways and in doing so I extended the power supply by several feet(2m) and added about a foot (1m) to the data/clock wires. Then I encountered this strange behavior. The first LED would rainbow swirl, sometimes skipping the blue color, and the second LED would flash and none of the other LEDs would light. Thinking the flashing LED was bad, I snipped it out and soldered the 1st to the 3rd but now the 3rd LED also flashed haphazardly. I then decided to cut the 1st. Called a friend over to run some tests and ended up shorting the RPI 3B somehow when we were testing with the unused strip of LEDs.
Now I have resoldered everything to this unused strip of LEDs, with a new RPI 3B+ (which randomly keeps dropping wifi and I need to manually reconnect via KODI menu) and I cannot even get Hyperion to run.
***
In between this and the last sentence, I went to bed, woke up, and formally soldered my level shifter together to a perf board and some jumper wire connectors. I currently have Hyperion running smooth, allegedly.[/INDENT]
/End background.
When I kill hyperion, I can take screenshots and they are accurate and when I try to control a color, I don't recieve any errors. Currently all of my LEDs are lit but only when I jostle the wire connections a bit. I am not able to change any colors.
What's truly frustrating to me is that I keep bouncing between thinking it's a hardware issue vs software issue. I'm un able to narrow it down. Scratch that, what's truly infuriating is that it was working before!
Can someone provide any input? I'll attach my config and SSH output below:
