The mikromedia+ for STM32 ARM®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+ for STM32 ARM®

features integrated modules such as stereo MP3 codec, 4.3’’ TFT

480x272 touch screen display, accelerometer, microSD card slot,

buzzer, IR receiver, RGB LED diode, PIN photodiode, temperature

sensor, 2.4GHz RF transceiver, Ethernet transceiver, 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 pre-programmed with USB HID bootloader, but

can also be programmed with external programmers, such as

mikroProg™ for STM32 or ST-LINK programmer. Mikromedia

is compact and slim, and perfectly ts in the palm of your hand,

which makes it a convenient platform for mobile and other

multimedia devices. We have also prepared a mikromedia+

SHIELD for STM32 ARM® extension board which enables you

to easily expand the functionality of your board.

USB power supply

The mikromedia+ for STM32 ARM® board can be powered in three dierent ways: via USB connector using MINI-B USB cable provided

with the board (CN4), via battery connector using Li-Polymer battery (CN5) or via screw terminals using laboratory 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 2.5-12V 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.

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.

Programming with mikroBootloader

Figure 3-2: USB HID mikroBootloader window

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.
