Good day eveyone, I've just started working on a quadrature encoder program for a mica2 mote, and I'm having some trouble figuring out how to access the individual external pins. It looks like I should be using the Get interface to get the value of (I think) Port A pins 4&5, which I will sample at a fairly high rate using one of the timers.
Two questions: (1) How do I wire the external pins so that I can sample them with a Get (or similar) command? (example code would be helpful here) (2) Is it possible to make this more general than just the mica2, or even atm chips? I figure I won't be the last guy to do this, so I'd rather do it right the first time. Many thanks, -tba
