Do you have any code to share? I fooled around with these modules a bit a couple of months ago (my first PIC project, loads of fun). I got things wokring fairly quickly, but need to improve my sync method. Work is still a bit hectic for me so no hobby time, but I'm going to get back to it. I'd be interested in other's approaches, like Bob Ammerman's sync methoded posted a couple of weeks ago.
