Unresponsive LEDs with LibreELEC on HTPC

  • Greetings to the community and thank you for all your amazing work.
    I decided to dive into the DIY Ambilight project, got a 5m ws2812b strip, a 5V20A power adapter to run the strip and an Arduino Uno. My current setup consists of a custom made Intel based HTPC running LibreELEC.
    So i hook the Arduino up on my PC, download the Adalight and FastLED libraries and upload the sketch that i read is mostly used:

    The LEDs go blink and so far so good.
    I then install Hyperion through LibreELEC's repository and connect Arduino to my HTPC via USB. I run Hypercon on my pc, connect through SSH and follow instructions to eventually upload this:

    And that's about it. No rainbow effect on my strip, no single colour when trying the colorpicker through SSH, nothing.
    Wanted to use an external grabber as well but i imagine i'm pretty far off until that's happening.
    Couldn't find people using an HTPC while running the Hyperion Ambilight, most use Rpi's so i couldn't find much help in the forums.
    Any assistance would be deeply appreciated. Many thanks in advance for your time and effort!


  • Thank you for your swift response. So you suggest i try different ports on my HTPC, correct? i actually tried a second one while i was messing around, but still nothing happened. I will give it a go and try them all and let you know.
    Thanks again!

  • ok so when i run the command through putty, i get two result while the Arduino is hooked. i get /dev/ttyACM0 and /dev/ttyACM1
    if i unplug it and run the command again, i just get /dev/tty/ACM0.
    i switched the hyperion config file to this:

    meaning i just typed ACM1 in the hypercon hardware output tab. now when i press start on hypercon to start hyperion all of my leds (300 while only 200 are specified) flash white two times and then nothing more.
