If the OP would contact me I would be happy to make a new PIC divider for his specific purpose. I do this all the time. It usually only takes a few minutes.
On the PIC 12F675, pin5 / GP2 is Schmitt trigger. See page 8 of 41190F-PIC-12F629-675.pdf But for push-button-start sorts of things input conditioning is unnecessary. It's only when a button is both start and stop or increment or decrement that you need to debounce and all that stuff. /tvb ----- Original Message ----- From: "Bryan _" <bpl...@outlook.com> To: "Discussion of precise time and frequency measurement" <time-nuts@febo.com> Sent: Thursday, November 17, 2016 1:26 PM Subject: Re: [time-nuts] precision timing pulse > Tom: > > > As you were gracious to release the source code for these excellent little > dividers, I would suspect someone who is somewhat fluent in assembly could > just modify so it counts a specific number of pulses and then toggles a > output off.
