Hi,

The DS1307 Uses the I2C interface. It has been long talked about in this board. Click on the search button on the top and write DS1307 and click search. There are so many links in the board that i could even start coyeing it...

If you found my answer useful, click on the button that says Helped me.

Good luck.

Better use CCS C compiler, it has ready function to execute an I2C command.

Hi,

I dont know if its "better" to use the C compiler - I suppose that depends on wether you can program C !

I have some generic I2C routines and will post them if you like, I'm using 16F877A with assembly right now on a project but using a PCF 8583, the code should work just fine.
