Introduction to mikromedia for XMEGA®
The mikromedia for XMEGA®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 8-bit ATxmega128A1
microcontroller. The mikromedia for XMEGA®
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
UART bootloader, but can also be programmed
with external PDI programmers. Mikromedia is
compact and slim, and perfectly ts in the palm
of your 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 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.

Microcontroller
The microcontroller can be programmed in two ways:

Page 12
You can program the microcontroller with UART bootloader which
is pre programmed by default. To transfer .hex le from a PC to
MCU you need bootloader software (mikroBootloader) which
can be downloaded from:
After the mikroBootloader software is downloaded unzip it to
desired location and start it.

The microcontroller can be programmed with external programmer (AVRISP mkII, AVR
JTAGICE mkII or other supported programer with PDI interface). The external
programmer is connected to the development system via pads marked with
PDI (CN5), Figure 3-11. In order to connect the external programmer to
the development system, it is necessary to solder a 2x3 male header
on the pad (CN5). If bootloader program is accidently erased you can
upload it again via external PDI programmer. Program
atxmega128a1_bootloader_rmware.hex
can be found under Firmware folder
(page 12).

Board is equipped with reset button, which is located
at the top of the front side (Figure 4-2). If you want
to reset the circuit, press the reset button. It will
generate low voltage level on microcontroller reset pin
(input). In addition, a reset can be externally provided
through pin 27 on side headers (Figure 4-3).
