Hi, all!

When setting time using the tm\_wr() func, only the six RTC registers are fed, leaving the free running counter where it was. This means that the seconds counter can increase as soon as I set the time or a bit less than one second later. Or to put it another way… I have two rabbits driving two time displays and the seconds digits do not change simultaneously since they were not started at the same time. There must be a way to reset the RTC counter that triggers the increase seconds interrupt? Anyone has a clue?

Regards,

over.
