A real-time clock is widely used in alarm devices, industrial controllers, consumer devices etc. Thanks to the PCF8583 circuit, the
UNI-
DS3
development system is capable of keeping the real time. The main features of the real-time clock are as follows:
- clock with calendar
- I
2
C serial interface
- universal counter used as an alarm
- ability to change the time format (12/24h)
The real-time clock provided on the
UNI-DS3
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 switch 1 on the DIP switch SW3, as well as switches
7 and 8 on the DIP switch SW4 to the ON position.
