Introduction to mikromedia 7 for STM32F4
The mikromedia 7 for STM32F4 is a compact development
system with lots of on-board peripherals which allow
development of devices with multimedia contents. The central
part of the system is a 32-bit ARM®Cortex™-M4 STM32F407ZG
144-pin microcontroller. The mikromedia 7 for STM32F4
features integrated modules such as stereo MP3 codec, 7” TFT
800x480 touch screen display. The increased screen size is ideal
for displaying larger amounts of data. The board also contains
an accelerometer, microSD card slot, buzzer, IR receiver, RGB
LED diode, PIN photodiode, temperature sensor, 2.4GHz RF, WiFi,
Ethernet and CAN transceivers, 8 Mbit ash memory, RTC battery,
Li-Polimer battery charger, etc. The board also contains MINI-B
USB connector, power screw terminals, 2x5 JTAG connector, two
1x26 connection pads, ON/OFF switch and other. It comes with
an onboard mikroProg™ for STM32 programmer and debugger,
but can also be programmed with external programmers, such
as ST-LINK programmer.

USB power supply
The mikromedia 7 for STM32F4 board can be powered in four dierent ways: via two USB connectors using MINI-B USB cable provided
with the board (CN4 or CN11),via battery connector using Li-Polymer battery (CN5) or via adapter connector using adapter power supply
(CN3). After you plug in the appropriate power supply turn the power switch ON (SW1). The USB connection can provide up to 500mA of
current which is more than enough for the operation of all on-board modules and the microcontroller as well. If you decide to use external
power supply via screw terminals, voltage values must be within 5-12V DC range. Power LED ON (GREEN) indicates the presence of power
supply. On-board battery charger circuit MCP73832 enables you to charge the battery over USB connection or via screw terminals. LED
diode (RED) indicates when battery is charging. Charging current is ~250mA and charging voltage is 4.2V DC.

Cortex-M3™and Cortex-M4™ microcontroller families. It features intuitive interface and
SingleClick™ programming technology. Software installation is available on following link:
www.mikroe.com/downloads/get/1809/mikroprog_suite_for_arm.zip
After downloading, extract the package and double click the executable setup le to start
installation.
Quick Guide
1. Click the Detect MCU button in order to recognize the device ID.
2. Click the Read button to read the entire microcontroller memory. You can click the Save
button to save it to the target HEX le.
3. If you want to write the HEX le into the microcontroller, rst make sure to load the
target HEX le using the Load button. Then click the Write button to begin programming.

RTC Battery
Reset Button
The board is equipped with reset button, which is
located on the front side of the board. If you want to
reset the circuit, press the reset button. It will gen-
erate low voltage level on the microcontroller reset
pin (input). A reset can also be externally provided
through the pin 26 on the side headers.
4. RTC Battery and Reset Button
mikromedia 7 for STM32F4 features an RTC
battery holder for microcontroller RTC module.
Battery is used as alternate source of power, so
the RTC module can continue to keep time while
the primacy source of power is o or currently
unavailable. Three types of coin battery are
supported: CR1216, CR1220 and CR1225.

crystal oscillator (X5) circuit that
provides external clock waveform to the
microcontroller OSCO and OSCI pins. This
base frequency is suitable for further clock
multipliers and ideal for generation of
necessary USB clock, which ensures proper
operation of bootloader and your custom
USB-based applications. The board also
contains 232.768 kHz crystal oscillator
(X4) which provides external clock for
internal RTCC module. Microcontroller ADC
requires an accurate source of reference
voltage signal. That is why we provide the
external 3voltage reference to the
microcontroller VREF pin which is 2.048V.

microSD card slot
6. microSD Card Slot
Board contains 1microSD card slot for using 2microSD cards in your projects.
It enables you to store large amounts of data externally, thus saving microcontroller
memory. microSD cards use Serial Peripheral Interface (SPI) for communication with the
microcontroller. Ferrite and capcitor are provided to compensate the voltage and current
glitch that can occur when pushing-in and pushing-out microSD card into the socket.
Proper insertion of the microSD card is shown in Figure 6-1.

Figure 6-2: microSD Card Slot module connection schematic

The development system features a 7‘‘
TFT 800x480 display covered with a
resistive touch panel. Together they form
a functional unit called a touch screen,
(Figure 7-1).It enables data to be entered
and displayed at the same time. The TFT
display is capable of showing graphics in
262K die rent colors.
