Hi Bruce,

Is it possible to assign a pin as an input, connect it to a counter and read the
accumulated number of clock transitions?

I'd like to implement frequency measurement of a relatively low frequency signal
by reading the counter, recording the time and repeating the sequence at some
later time.

Best regards,

Jim

What you are looking for is to run the counter/timer in counter mode. There are
2 available in the ARMweb. (2 and 3).
