Setup:
- Pi 3B+
- LibreELEC 9.2.6
- hyperion.ng alpha9 (installed with script from paulchen.panther)
- LEDs are SK6812
- Wire from PI to LEDs is shielded
- Power to stripe on two opposite corners
- 100Ohm resistor on data wire
- Config:
- 166 LEDs
- WS281x (PWM) on GPIO18
- RGBW enabled
I got this running normally for one time on a test-setup. Afterwards i did a shutdown and rerouted the wires to the final layout (no connections changed, just unplugged and replugged them). From this on i got the following error:
On startup there is like 1 or 2 seconds of the boot-animation (knight rider in my case) and then the animation freezes and the first 2-3 LEDs are white or green (looking like there is noise on the wire or so, but i use a shielded wire and a 100Ohm Resistor to minimize these effects). On the webinterface i can see the video feed correctly and if i select a color from my app the preview in the webview changed the color, but it is not applied to the real leds. If i stop and start the hyperion service all LEDs are flickering random (brightness of flickering changes with the USB grabber enabled).
Anyone got a suggestion to this?
