Hi Alexis,

The DS1307 device is connected using the I2C bus. First start looking how it is working and how to use it on your MCU (for example looking at this: http://cache.freescale.com/files/microcontrollers/doc/app_note/AN3291.pdf?fsrch=1&sr=8) ! Then, the datasheet of the DS1307 will be useful to know how you can read/write the date.
