Hi,
I run a lot of DMX-512 compatible lighting equipment and I am wondering if anyone knows how I could make a small 4 channel output unit using DMX control signals. The idea is this:
Use a chip with some code which accepts the DMX + and - signal on two of its inputs, probably through optoisolators. It'll have it's DMX address hard coded.
I want to have 4 outputs on the pic respond to the 4 input channels. IE, it'll use DMX channels 1-4, and if channel 1 is set to more than 50% (128) then it'll output the normal 5v for connection to LEDs on one of its outputs. And these will be mutually exculsive - no channels will affect each other, they'll work independantly).
anyone know of a guide or have ideas I can use?
