I got the package from China with some ICs I wanted to try before embedding them to the clock project I want to make. Have to warn: my point of interest was just a time, the date was out of the scope, so nothing about it will be investigated further.

Goal: To write the value of the time/read the time and output it thru UART from the DS1307 chip

Tools: PIC16f628a, DS1307, MAX232 level converter, devboard, proteus.
