There is ample documentation on the site and surprisingly, the SX28 datasheet has a very nice register mode summary. My insistence on syntax was to pin down the code to reconcile some different ways within the literature I have seen things done, and I consider myself now to be correctly programmed : ). I went ahead and recoded by toggling the output register and not the direction ports. Works OK. But now you and Mr.PJ Monty had to go and "muck it up" (hehe) by getting me interested in the ISR approach. Before I read up on it, but please explain to me why this would be better (big picture stuff) in acheiving accuracy so I understand.
