We won't pull this, but this is the code we have for testing right now.

We are having some difficulty with FERR detection. We think that it is only getting a framing error some of the times when it should be. I'll look into this if I have time, but if @aterlumen wants to help out too, that'd be great.

My approach is going to be "rewriting" the recipe for DMX reception based on my knowledge of the protocol, the USART, and the Technote we have on the Wiki for DMX.
