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 a 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, MMC/SD card
slot, 8 Mbit ash memory, battery charger. The
board also contains MINI-B USB connector, two 1x26
connection pads and other. It comes pre-programmed
with USB HID bootloader, but can also be programmed
with external programmers, such as mikroProg™ for
Stellaris®or JTAG programmer. Mikromedia is compact
and slim, and perfectly ts in the palm of your hand,
which makes it a 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 battery charger
circuit MCP73832 enables you to charge the battery
over USB connection. LED diode (RED) will indicate
when battery is charging. Charging current is ~250mA
and charging voltage is 4.2V DC.

Page 12
Page 13
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.

The microcontroller can be programmed
with external mikroProg™programmer
and mikroProg™for Stellaris®software.
The external programmer is connected to
the developmentsystemviaJTAGconnector,
Figure 3-9. mikroProg™is a fast USB 2.0
programmer with hardware Debugger
support. It supports ARM®Cortex™-M3 and
Cortex™-M4 microcontrollers from Stellaris®.
Outstanding performance, easy operation
and elegant design are it’s key features.

Board is equipped with 8MHz crystal oscillator
(X1) circuit that provides external clock waveform
to the microcontroller OSC0 and OSC1 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.
