Hi there!.
I am using a RTC DS1307 with a PIC18F252 and already write and read the
RTC´s registers by I2C protocol; nevertheless when I consult the
seconds register, I notice that the RTC works 9 times slower of the
normal thing; my theory is that it is due to the crystal that I am
using...., which seems to me strange is the slow thing...
Well, here come my questions...
* Some one know if in fact this device (DS1307) is so sensible when
using an unsuitable crystal?
* Which other factor could influence in this behavior?
* Could be a firmware problem? (I don´t think so)
Many Thanks
Andros!
