Feature Request: Add Support for DMD with MPF SmartMatrix Teensy Boards #255

Hi, Is it possible to add basic (output)support for the SmartMatrix based MPF DMD firmware ? The MPF is using this sketch on the teensy: link for receiving the frames.

Okay I've discussed this with @ecurtz months ago but for some reason didn't post the conclusion here. As far as I understood:

You can run different firmwares on the Teensy, most use the RGB_DMD or something compatible
It supports RGB888 frames, as well as 4/8-bit color tables
Bus is over serial, an 8-byte header, and 312832 bytes of pixel data

We'll have a goal at this once VPE gets DMD support.

The last time I tried to do high speed serial from Unity on my preferred platform (OS X) it required a few extra hoops to get the connection initialized but that's the only potential issue and I'm not sure if that will still exist (it was a couple years ago) or what platforms might require some extra work.

Out of curiosity, has there been any news/progress on this?

No, but I don't see any reason to not go ahead with it. @ecurtz would you be able to help me with implementing a driver?
