Introduction to mikromedia for STM32®
The mikromedia for STM32® 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 STM32F207VGT6
or STM32F407VGT6 microcontroller. The
mikromedia for STM32® features integrated
modules such as stereo MP3 codec, TFT
320x240 touch screen display, accelerometer,
USB connector, MMC/SD card slot, 8 Mbit ash
memory, 2x26 connection pads and other. It
comes pre-programmed with USB bootloader,
but can also be programmed with external
programmers, such as mikroProg™ for STM32®
or ST-LINK. Mikromedia is compact and slim,
and perfectly ts in the palm of the hand, which
makes it convenient platform for mobile devices.

1. Power supply
You can apply power supply to the board
using MINI-B USB cable provided with
the board. On-board voltage regulators
provide the appropriate voltage levels
to each component on the board. Power
LED (GREEN) will indicate the presence of
power supply.
You can also power the board using Li-Polymer battery,
via on-board battery connector. On-board circuit
MCP73832 enables you to charge the battery over
USB connection. LED diode (RED) will indicate battery
charging. Led is o when battery is full. Charging current
is ~250mA and charging voltage is 4.2V DC.

Via USB mikroBootloader Using external mikroProg™
programmer
03 Using external ST-LINK V2™
programmer
The mikromedia for STM32® development system can be programmed in three dierent ways. 01 Using bootloader which is
pre-programmed into device by default or via external programmers ( 02 mikroProg™ or 03 ST-LINK V2™) .

Programming with mikroBootloader
You can program the microcontroller with bootloader which
is pre-programmed into the device by default. To transfer
.HEX le from a PC to MCU you need bootloader software
(mikroBootloader USB HID) which can be downloaded from:
After software is downloaded unzip it to desired location and
start mikroBootloader USB HID software.

step 1 – Connecting mikromedia
01 To start, connect the USB cable, or if already connected
press the Reset button on your mikromedia board. Click the
”Connect” button within 5s to enter the bootloader mode,
otherwise existing microcontroller program will execute.

The microcontroller can be programmed with external mikroProg™ for STM32® programmer and mikroProg Suite™ for ARM® software.
The mikroProg™ programmer is connected to the development system via the CN5 (JTAG) connector. You can choose between two ways to
program microcontrollers , Figure 3-14:

On-board mikroProg™ programmer requires special programming software called mikroProg
Suite™ for ARM®. This software is used for programming of all supported microcontroller
families with ARM® Cortex™-M3 and Cortex™-M4 cores. Software has intuitive
interface and SingleClick™ programming technology. To begin, rst locate the
installation archive on the Product DVD:
Click the Detect MCU button in order to recognize the device ID.
Click the Read button to read the entire microcontroller memory. You can click the Save
button to save it to target HEX le.
If you want to write the HEX le to the microcontroller, rst make sure to load the target
HEX le. You can drag-n-drop the le onto the software window, or use the Load button to
open Browse dialog and point to the HEX le location. Then click the Write button to begin
programming.
After downloading, extract the package and double click the executable
setup le, to start installation.

The microcontroller can be also programmed with ST-LINK V2 programmer and
mikroProg Suite™ for ARM® software, Figure 3-11 . This programmer connects
with mikromedia board via mikroProg to ST-LINK V2 adapter.
Programming with ST-LINK V2 programmer
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
CN5 connector pads. Then you should plug adapter into
the ST-LINK V2 programmer (2x10 male header), and plug
IDC10 at cable in male headers, Figure 3-13
