Hello again, Had no time to start new thread but have tried to make RPi work already. What I've done so far. 1. Reinstalled OpenELEC on RPi3 2. Activated Remote control 3. Installed Hyperion with HyperCon V1.02.3 () 4. Created Config file for shorter led strip (38 LED) () 5. Checked with multimeter if on each led segment is voltage 6. Checked data voltage from beggining of the strip till last led (unfortunately first led was broken so i connected data line to second one) 7. Tried to light up leds run manually hyperion but error occurs: () Thank you in advance. And sorry for bothering.
