DMX-Interface to use to write your own DMX-Control-Software

Question

I have a very specific problem: I want to write my own DMX-Software to control our DMX-fixtures. Does anyone know a interface to use? It would be great if there would be any Framework for using it, so that I only have to sent the channel and the value to the interface.

Answer 1

There's some really good information & code samples (including a working class that I wrote) here: Lighting USB OpenDMX FTD2XX DMXking

Ultimately, you end up setting byte values (between 0 and 255[FF] (brightest) in a byte array. It's fairly trivial to implement simple effects such as fades or chases.

You would need to use a USB controller to convert your program's instructions to the actual hardware. I suggest using a simple iphone application talking to a webservice which then interacts with the hardware.

Code samples above are in c# though will show you how to interact with a DMX controller

Answer 2

I noticed your question was for Mac, but I wrote a Windows specific C++ program, which could probably be easily modified. It's adapted from the C# example on Enttec's OpenUSB website. See: https://github.com/chloelle/DMX_CPP
