BRAVO! BRAVO!

Fantastic!

Talk about lateral thinking!

I have 2 observations:  I don't see any way for the routine to time out.  It
looks as if I can either look after the watchdog or have timeout capability
but not both.  I'll keep looking, tho.

The other observation is slightly more serious, I think.  If the routine
exits without incrementing any counters, (enters the routine but the pin
went or was non-active - zero time) an erroneous result will occur.  I think
the solution is simple: relpace the 'SKPZ' below with 'SKPC'.  Of course - I
might be out to lunch . . .

This is at the end of the normalisation routine:

This is extremely impressive, Scott.  Many thanks.
