Dear all.

I m looking for code that interface msp430 and ds1307. i searched ti website couldn't find any. else share link where i can understand following configuration

i2cinit()
i2cread()'
i2cwrite()
i2ccommunicate()
i2c start()
i2c stop()

The MSP430G2553 can use a 32.768 kHz crystal oscillator for an RTC. Why do you need a DS1307?

Please elaborate below line, I am using ds1307 , to work my application work on real time clock
