I have read oodles of information about setting up Hyperion. Nowhere can I find a wiring diagram for how the lights should get their data signal. I feel like I must be crazy because this is such a critical component. Can someone please advise?
I can use an RPi 2B/2GB or 4B/2GB. I have an HDMI capture device (but would be open to one that's better as the one I have doesn't seem to properly pass UHD to my LG OLED), WS2815 lights with 60 LEDs per meter, 12V/8.3A power supply, and DC-DC 12V-5V transformer.
Do I need another device like NodeMCU (i have one) or Arduino Nano (i have one) or USB ISP/ASP (in order)? Can someone share a basic wiring diagram? Can I just use a GPIO pin on the RPi? What about if I use the PoE HAT on the RPi 4B?
