The author of PicDiv publishes the ASM code for his dividers. If fluent in assembley(er) it's probably quite doable. Many of the examples have a ARM or SYNC feature http://www.leapsecond.com/pic/picdiv.htm -=Bryan=- ________________________________ From: time-nuts <time-nuts-bounces@febo.com> on behalf of Hal Murray <hmurray@megapathdsl.net> Sent: November 15, 2016 12:17 PM To: Discussion of precise time and frequency measurement Cc: hmurray@megapathdsl.net Subject: Re: [time-nuts] precision timing pulse ciandjaburch@gmail.com said: > How do I get a pulse to start with a push button and then stop for example > 500 or 10,000 seconds later?

The PicDiv does something not needed for this use case. It produces a nice usable output frequency. You don't need that, you only need to know when X number of cycles have completed. It is an order of magnitude simpler problem. Just count to X then stop, that's it.

Exactly and counting gps seconds may be useful. Anyhow will be curious to see what he is counting.
