I'm still looking for an example code that uses a capture register on an
Arduino.
I see how to access it from software but not the part about an external
signal causing a timer capture.

I think I read this was on page 125 of "the documentation" but there is
LOTs of documentation and data sheets and version of each.

I just got a couple small LCD graphic panels from China.  Free shipping got
them here is just a few days.  Cost $2.60 each. They should make for a nice
status display.
