I have same problem, on coreelec
My First post!
My current setup is a Coreelec running on a Odroid N2, with the hyperion.ng add-on. A USB cable then to a Arduino uno and this controls the WS2811 leds around the 60" TV and all it work fine, I really like it.
I see a lot of people using things like Raspberry pi, capture cards, a camera etc.
I guess my question is, is there any advantage to using the other hardware?
or should I just keep doing what I am doing..
I reckon I will order some next week, should be able just swap out the leds in my setup and keep everything else as is..
Yes, I found them by chance the other day when looking for an alternative to my current 2811. It looks like you can get it in doubles or triples.
