I am using a 595 shift register to extend the number of outputs from my Arduino board. I need to control 24 channels (3) shift registers.

My questions is - does anyone know how to write the code for Arduino so that Vixen see's the "extended" Arduino outputs - from the
shift register - as channels?

Thanks

Well I found this
http://arduino.cc/en/Tutorial/ShiftOut
Which gives the easy part.
As far as Vixen, generally it doesn't "see" outputs (at least not without a lot of code). Generally you tell vixen the output type (I assume you are talking to the Arduino serially) and how many channels are hanging it off it.
Probably just get away with using the generic serial output and having the Arduino convert non zero channels into 1 outputs on the serial stream.
Keep in mind, what I suggest will not allow for dimming.

Covewi posted essentially the same question in the Arduino forum...let's keep the discussion in one place in that forum.
