Arduino Due DMX libraries

Please,i want to use dmx library like dmxSimple,with arduino Due,but it doesn´t work on Due.
Someone knows,how to re-write dmx libraries to work with Due???

Do not cross-post. Other threads removed.

I ported DmxSimple to Teensy 3.x quite some time ago. Arduino Due has very similar hardware, so maybe it would at least help anyone who wanted to also port to Due?
