Hi Nantonos,
I hope I didn't step on your toes there, I just thought that after bagging Arduino documentation for ages I should actually contribute something and went for it.
BTW I haven't added the interrupts yet, I'll grab them off your drawing but still need to verify. Where did you get the data from, I seem to remember we had a thread about this but I can't find anything in Winterrupts.c or.h
