I want to use RTC DS1307 with PIC16F676. Is there any library function which can do this?
Please guide me.
Regards

Look in your CCS drivers directory:
| Quote: | c:\program files\picc\drivers\ds1302.c
|
Also, it's SPI, not i2c. |

There have been drivers posted here for this. For example:

A search will find others. |

I've done several products using the DS1307, it's easy to use and keeps great time. Just be sure to install the battery ! I use the 1Hz interrupt to trigger a remote temp/control data product.
Also if you need to store a few variables, the onboard battery backed RAM is great ! Somewhat easier than EEPROM routines as you can just save/read ONE byte not a 'block'.
