how to make a simple dmx controller

Okay, I'm a total noob and need all the help that I can get. Here's the deal: arduino mega 2560, w5100 ethernet shield, tinkerkit dmx shield, wireless linksys router, ipad. Trying to make a simple dmx controller that uses DMXSimple and OSC. Has anyone done this before? Tutorials, links, anything? I haven't found an OSC library that works well either, github is not my friend.
