Thanks. I couldn't find the pin mapping in the docs.
I am using the XDIO api that is provided...nice job, Michael!
I was wondering how people were tying measurements to accurate timing.
Is there an easy and accurate way to determine the delta t between
counter readings? Is there a better way than using gettimeofday?
