Got all the hardware together that works with an Apple TV 4k. Hopefully this documentation helps someone out!
Hardware:
- Raspberry Pi 3 b+
- Arduino Nano or Uno with WS2812B lights
- splitter (4k 60hz, 1x2, 4:2:0 color)
- Grabber -
- HDMI --> RCA Converter -
- 3A external power supply for ws2812 lights (65" TV). Otherwise everything else hooked into USB ports of Pi.
Software
- Hyperion.NG Alpha 6
- adalight.ino loaded on arduino -
- Baudrate set to 1,000,000
Misc Notes
- I tried a digital HDMI grabber:
- It works, but is laggy. The hdmi-->rca-->grabber is a lot faster. I'd say the HDMI grabber was ~.5sec slower. I wonder if a pi4 would do better? - Was not able to get ws2812b lights working straight from Pi. Although I hear it's buggy, I still wanted to try, but no luck.
- I was able to get 4:2:2 color to work on another 1x2 splitter, but it was a little buggy. Video would cut out or not reach the Pi.
- For anyone less knowledgeable about installing .deb files for Hyperion.NG - the easy way is to install the full desktop image for Pi, hook up a mouse, keyboard an monitor and use the UI to install the .deb file.
