BigPIC6 Development System
BigPIC6 Development System
12.0. Real-Time Clock (RTC)
The DS1307 circuit enables the BigPIC6 development system to keep the real time. The real-time clock’s main features are as follows:
The real-time clock is widely used in alarm devices, industrial controllers, mass-consumption products etc. The real-time clock provided
on the BigPIC6 development system is used to generate an interrupt at pre-set time. In order to establish the connection between the
microcontroller and real-time clock it is necessary to set switches RC4, RC3 and RB0 on the DIP switch SW13 to ON position.
