The DS1307 circuit enables the
BIGdsPIC6
development system to keep the real time. The real-time clock’s main features are as follows:
- providing information on seconds, minutes, hours, days, days in a week and dates including corrections for a leap year
- I
2
C serial interface
- automatic power-fail detection
- power consumption less than 500nA
The real-time clock is widely used in alarm devices, industrial controllers, mass-consumption products etc. The real-time clock provided
on the
BIGdsPIC6
development system is used to generate an interrupt at pre-set time. In order to establish connection between the
microcontroller and real-time clock it is necessary to set switches RG3, RG2 and RA15 on the DIP switch SW12 to the ON position.
