hello,
im using hyperion now for months without problems. now i ran in one, but its confusing me.
the leds working perfect for the first 2-3 mins. even if i restart the raspi or something. i can see the color rainbow swirl.
after a time just 1/4 stop working. the rest works still fine than.
e.g. when im using a red background, all leds are red. after 3mins i switch to a blue background, 1/4 stays on red and the rest is switching to blue just fine.
when i restart the pi, than all is working again for some mins, than the same weired thing is happening.
what could i do?! i checked the solders and so on...all seems to be just fine.
my setup:
- raspi 3b with raspbian jessi
- apa102 leds
- hyperion config should be alright, i didnt change something. as i said, it worked for months...
- im using a avr. from this output i got the hdmi splitter sticked in. but it doesnt matter if i use the avr output, or using my odroid c2 direct output - same thing is happening
i attached some screenshots. maybe the could help?
in the screenshot with the blue kodi background, there you can see, the "last used color" when all was working (e.g. after a raspi restart) was white...after 2-3mins the background changed to that blue one and just in the corner it stays white...after a raspi restart its working again for some mins.
now im running out of ideas what i could try.
