UIRT2 with RTC

[dietmar]

Hi,

is it possible to expand the uirt2 with a RealtimeClock?
I want to wake up my pc at a specific time for recording.

For the RTC ( are 3 pins needed. Two for the programing (Data+Clock) and one as signal for wakeup.

Thanks
Dietmar

Me too ! (But then I already mentioned that) :D

Does the UIRT support interrupts when a PIC pin is pulsed ?

I think most motherboards have wake at specific time. It should be easier to write a program to update the values needed into onboard CMOS, then building an external RTC.

Been there, done that ...

There's an application called ByAlarm that claims to do exactly that, but you have to have one of the supported motherboards ...

What was this RTC device you were thinking of ?

my problem is that my mb have not such function, so that i must build a external device to wakeup.

The RTC i want to use is from Maxim DS1337.
