Problem working with RTC DS1337.

srj0408:
I think i figured out the problem, but i am not sure though. I think its due to some registers settings

I my header file for DS1337, i am using these settings

#define DS1337_SP			0x0E

#define DS1337_SP_EOSC B00000000
#define DS1337_SP_RS2 B00010000
#define DS1337_SP_RS1 B00001000
#define DS1337_SP_INTCN B00000000
#define DS1337_SP_A2IE B00000010
#define DS1337_SP_A1IE B00000001

I dont know your header file, nor your library, but I think it should be something like this (I did not check the datasheet for corresponding bits, just an example derrived from what you provided)

#define DS1337_SP	 B00011011

Anyway, dump the whole code above to see if you could get it working, on startup, the DS1337 should load default values on startup with oscillator == ON.
