Re: PIC Input Capture

Forgot. You should also disable interrupts while calculating your pulse with
and pulse interval since the values you are using can change at any time if you
don't. If you don't, you'd still get weird values. Say  this happens:

MOVF    low(fall),w
<CCP2 int happens here>
SUBWF  low(last_fall),w

You'd get an interval of 0 once more.

Thanks for your help, I'm getting better results by dis/ena interupts, but
how do I reset the Timer1 value, so that I can get more consistent
(synchronous) results?
TIA
