I achieve syncing of the interrupts via the data edges (and NOT by interrupt-on-port B...way too slow), and once we are synced we can bit-bang at will without ever missing a bit, provided of course there are enough cycles in the software to go around.
 

[i]How do you edge detect w/o port B interrupts? Do you do rapid polling at the expected region of transition?[/i]

I believe I have properly solved the resonator precision issue by proper design, and until your communications are 100% solid with your components of choice, I think you still have some issues to resolve.

 

[/quote]I concur, if resonators must be matched for proper communications to occur in bench testing, the developed com scheme isn't robust enough to endure Murphy's influence when it is deployed in the feild. Fixing a problem in the field can be 10x as costly than fixing it on the bench, especially if you find you need to completely redesign the system. I just wish I had more com experience to help you Dan, but it seems as though Peter does.
