Introduction to mikromedia for STM32®
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. 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 a Li-Polymer battery,
via on-board battery connector. On-board battery
charger circuit MCP73832 enables you to charge the
battery over a USB connection. LED diode (RED) will
indicate when the battery is charging. 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 the bootloader which is
preprogrammed into the device by default or via external programmers ( 02 mikroProg™or 03 ST-LINK V2™) .

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.
You can program the microcontroller with bootloader which
is preprogrammed 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:
Upon download, unzip it to desired location and start the
mikroBootloader application:

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:

mikroProg™
is a fast USB 2.0
programmer with mikroICD™
hardware In-Circuit Debugger.
It supports over 180 ARM®Cortex™
M3 and Cortex™M4 microcontrollers from
STM32®family. Outstanding performance, easy
operation and elegant design are its key features.

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. The software has an intuitive interface and SingleClick™
programming technology. To begin, rst locate the installation archive on the link bellow:

The microcontroller can also be programmed with the 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 the adapter into the ST-LINK V2
programmer (2x10 header), and plug an IDC10
at cable in headers, Figure 3-13
