Ah, thanks Sean! I didn't spot the code link when I read it last fall. (Duh... 4 months back, but same thread no less.) I'll need to try it.
Now *I* am confused... If Dave's serial method is working, why oh why are people still attempting PWM interfacing??? That's messy, more wiring, special connectors, prone to noise, AND may have timing problems.
As long as the data rate is decent (and the CPU overhead to service it is low), serial is a much more reliable method, AND less wiring is required.
Is there some drawback to Dave's way that I'm not seeing that's prompted more experimentation?
