I would hack up some way to grab a clump (say 10) of samples and print them
out where you can capture them on a PC and analyze them.
I'd start by looking with the old Mark 1 eyeballs, then write hack code to
filter out the good stuff so I can see the bad/interesting cases.
If you have a scope, it might be interesting to trigger on PPS and look at
the ADC trigger and input voltage. If you have a digital scope with the
remember forever option, that would catch the delayed interrupt bug that Jim
The simple way to discard occasional bogus samples is to loop until you get 2
These are my opinions. I hate spam.
