2.7.2 Calendar
The STM32F100ZET6 features a real-time clock (RTC) that provides a set of continuously
running counters. These can be used, with suitable software, to implement a clock-calendar
function. The counter values can be written to set the current time of the system.
This submenu is used to configure the time, date and alarm. The date, time and alarm
settings are not lost when the board is powered off owing to the battery connected to the
V
BAT
pin. The V
BAT
pin supplies power to the RTC unit, allowing the RTC to operate even
when the main digital supply (V
DD
) is turned off.
Note:
To be able to use the battery to back up the RTC, the JP1 jumper must be in the position
Battery-VDD on the STM32100E-EVAL board.
In any submenu, if the time and date parameters have not yet been configured, the
message shown in
Figure 22
is displayed on the LCD screen.
