Introduction to mikromedia for dsPIC33®
The mikromedia for dsPIC33® 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 16-bit dsPIC33FJ256GP710A
microcontroller. The mikromedia for dsPIC33
features integrated modules such as stereo MP3
codec, TFT 320x240 touch screen display,
accelerometer, USB connector, audio connector,
MMC/SD card slot, 8 Mbit ash memory, 2x26
connection pads and other. It comes pre-
programmed with UART bootloader, but can also
be programmed with external programmers,
such as mikroProg™ or ICD2/3. 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 of 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
battery charging. Led is o when battery is full. Charging
current is ~250mA and charging voltage is 4.2V DC.

Programming with mikroBootloader
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 (ds30 Loader)
which can be downloaded from:
After software is downloaded unzip it to desired location and
start ds30 Loader software.

The microcontroller can be programmed with mikroProg™
programmer and mikroProg Suite™ fo PIC® software. The
mikroProg™ programmer is connected to the development
system via the CN6 connector, Figure 3-12.
mikroProg™ is a
fast USB 2.0 programmer
with mikroICD™ hardware
In-Circuit Debugger. Smart engineering
allows mikroProg™ to support PIC10®,
PIC12®, PIC16®, PIC18®, dsPIC30/33®, PIC24® and
PIC32® devices in a single programmer. It supports over
570 microcontrollers from Microchip®. Outstanding performance,
easy operation and elegant design are it’s key features.

mikroProg Suite™for PIC®Software
mikroProg™ programmer requires
special programming software called
mikroProg Suite™ for PIC®. This
software is used for programming
of ALL Microchip® microcontroller
families, including PIC10®, PIC12®,
PIC16®, PIC18®, dsPIC30/33®, PIC24®
and PIC32®. Software has intuitive
interface and SingleClick™ programming
technology. Just by downloading the
latest version of mikroProg Suite™
your programmer is ready to program
new devices. mikroProg Suite™ is
updated regularly, at least four times a
year, so your programmer will be more
and more powerful with each new
release. Figure 3-13: Main Window of mikroProg Suite™ for PIC® programming software

Placing ICD2®
connector
The microcontroller can be also programmed with ICD2®
or ICD3® programmer. These programmers connects
with mikromedia board via ICD2 CONNECTOR BOARD.
Programming with
ICD2®or ICD3®programmer
In order to enable the ICD2® and ICD3® programmers to be connected to the
development system, it is necessary to provide the appropriate connector such as the
ICD2 CONNECTOR BOARD. This connector should be rst soldered on the CN5 connector.
Then you should plug the ICD2® or ICD3® programmer into it, Figure 3-14.
