Subject: Re: Atompro timing anomolies....

Thanks for the compliment. I'm more of an engineer (actually I'm a
manager) and less of a musician. I never record but mostly play and I
don't have a great sense of timing so my questions about accuracy are
truly from ignorance.

What I have been pondering is whether the inherent accuracy of the
AtomPro needs to be improved, or if it could be accomplished through
synchronization. The issue is there isn't much processing time
available if 1mS resolution is required.

I have to read your references from the other posting but I'm starting
to think we need to improve the accuracy with a crystal oscillator and
then use synchronization at a much longer time interval or perhaps
just at initialization to sync them together. The available pins do
provide edge-sensitive interrupts so a single external event should
be able to easily synchronize the. I do have a spare AtomPro28 and may
try to see if I can get an oscillator or crystal to fit. That's some
serial rework, though.
