how to write a new display output driver? #112

Open Dahrkael opened 4 years ago

Dahrkael commented 4 years ago

I have some Yeelight bulbs in my living room and I would like to output to them, but I don't see any documentation on how to write a new display (or how the existing ones work exactly). Yeelight music mode works by telling the bulb to connect to a TCP server, which then will send json commands at whatever rate. My theory is that I can manage the bulbs with any of the available external programs and point them to connect to colorchord (assuming I can run a TCP server inside somewhere), then just spit some hardcoded json sprintf'd with the required brightness and color values.

does that make sense? is it possible? any hints? thanks

You could copy-and-paste DisplayNetwork, and modify it to your needs. It has an example UDP client, and making a TCP server wouldn't be bad. As long as the JSON is cleanly formatted it should be pretty easy to generate with some sprintfs.
