All Mikroelektronika’s development systems feature a large number of peripheral
modules expanding microcontroller’s range of application and making the
process of program testing easier. In addition to these modules, it is also
possible to use numerous additional modules linked to the development system
through the I/O port connectors. Some of these additional modules can operate
as stand-alone devices without being connected to the microcontroller.
RTC PROTO
RTC PROTO (Real time clock PROTO)
The
RTC PROTO
enables the microcontroller to keep the real time and date, providing the alarm function. It is used to generate an
interrupt. Due to baterry cell the
RTC PROTO
enables the microcontroller to keep the real time when the power supply is off. The
RTC
PROTO
is linked to the development system by connecting 1x5 male connector provided on the additional board to the proto board
provided on the development system’s ports. The
RTC PROTO
communicates to the microcontroller by using the serial I
2
C interface.
The
RTC PROTO
is placed on the development system’s port that is connected to the built-in I
2
C microcontroller module.
