Introduction to mikromedia for Stellaris®M3
The mikromedia for Stellaris®M3 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 the 32-bit ARM®Cortex™-M3
LM3S9B95 microcontroller. The mikromedia for
Stellaris® M3 features integrated modules such as
stereo MP3 codec, TFT 320x240 touch screen
display, accelerometer, USB connector, MMC/SD
card slot and other. It comes pre-programmed with
USB bootloader, but can also be programmed
with external mikroProg™ for Stellaris® or JTAG
programmer. Mikromedia is compact and slim, and
perfectly ts in the palm of the hand, which makes
it convenient platform for mobile devices.

You can also power the board using
Li-Polymer battery, via on-board
battery connector. On-board battery
charger circuit MCP73832 enables
you to charge the battery over USB
connection. Charging current is ~250mA
and charging voltage is 4.2V DC.

Board contains microSD card slot for using microSD 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.
Figure 6-3:
Inserting microSD card
Figure 6-1:
microSD card slot
Figure 6-2: microSD Card Slot module connection schematics

The development system features a TFT 320x240
display covered with a resistive touch panel.
Together they form a functional unit called a touch
screen. It enables data to be entered and displayed
at the same time. The TFT display is capable of
showing data in 262.000 die rent colors.
