Anyone having a reference design or an idea on how to have a RTC as a NiosII peripheral ? The considered design shall use an EP1C3 + EPCS1SI8. Thanks! Cheers Franck P.

Hello:

I used the BQ4845 from TI. It's got an 8 bit parallel interface which is suitable for my system.

32khz crystal and battery input pin.

so does this make a 3 way to implement a RTC. Just kidding.

Next for me is the time.h stuff from C. I'm scheduling things at sunrise and sunset any where in the world.

Good Luck

George
