Hi Hank

The second comp int should not reset the timer to 0. Comp1 int is your reference point and you zero the timer in there. Comp2 int will not come if there is no comp1 signal. This is from your circuit.

So, if you see my previous postings on the other thread,
COMP1 int
read the timer (gets you frequency counts)
Timer Reset

COMP2 Int
read the timer (gets you phase counts)


These should be the only steps involved. I think you will be successful in this

Regards
