Dear Cypress friends,
Part 1: I am interested in being able to sychronize the RTC to an external 1 pulse per second GPS signal.
If possible, I would like to be able to have fairly quick synchronization between RTC and the GPS signal.
Part 2: I would also like to be able to create Years:Months:Days:hours:seconds: and also subseconds.
The RTC gives me all but the subseconds. Is there a straight forward way to do this but taping into a prescaler of the RTC?
I would be very grateful for any feedback,
kind regards,
John

There is a way to use any external 1PPS signal to drive the RTC component. Please see this thread in this regard, http://secure.cypress.com/?app=forum&id=2233&rID=51134.
