The microcontroller can also
be programmed with the
ST-LINK V2 programmer
and mikroProg Suite™for
ARM®software, Figure 5-1.
This programmer connects
with mikromedia board via
mikroProg to ST-LINK V2
adapter (Figure 4-11).

In order to adjust the ST-LINK™V2 programmer
to be connected to the development system, it
is necessary to provide the appropriate adapter
such as the mikroProg to ST-LINK V2 adapter.
2x5 male headers should be rst soldered on
the CN2 connector pads. Then you should plug
the adapter into the ST-LINK V2 programmer
(2x10 header), and plug an IDC10 at cable in
headers, Figure 4-12.

5. Buttons and LEDs
The board also contains a 01 reset button and a pair of 02 buttons and 03 LEDs. Each of these additional peripherals are located
in the bottom area of the board. Reset button is used to manually reset the microcontroller. Pressing the reset button will generate
a low voltage level on microcontroller’s reset pin. LEDs can be used for visual indication of the logic state on two pins (RA0 and RA1).
An active LED indicates that a logic high (1) is present on the pin. Pressing any of these buttons can change the logic state of the
microcontroller pins (RD2 and RD3) from logic high (1) to logic low (0).

6. RTC battery
STM32 M4 clicker features RTC battery pads for
powering microntroller’s internal RTC module. Battery
is used as an alternative source of power, so the
RTC module can keep track of time while primary
source of power is OFF or unavailable. In order to
use this option it is necessary to connect (solder)
external battery (type CR2032; voltage range from
1.65 to 3.6 V) and unsolder jumper J1, Figure 6-1.
Make sure that orientation of the battery is correct
(plus on VBAT and minus on GND pad), otherwise it
won’t work properly.
