Introduction to mikromedia for PIC24
The mikromedia for PIC24 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 PIC24FJ256GB110
microcontroller. The mikromedia for PIC24
features integrated modules such as stereo MP3
codec, TFT 320x240 touch screen display,
accelerometer, USB connector, MMC/SD card
slot and other. It comes preprogrammed with
USB 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.

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 3-8.
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
ALL of 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 3-9: Main Window of mikroProg Suite for PIC programming software

Placing ICD2 connector
The microcontroller can be also programmed with ICD2 or
ICD3 programmer. These programmer is connected with
mikromedia board via ICD2 CONNECTOR BOARD.
Programing 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, Figure 5-1. Then you should plug in the ICD2
or ICD3 programmer into it, Figure 5-2.

Board contains microSD card slot for using microSD
cards in your projects. It enables you to store
large ammounts of data externally, thus saving
microcontroller memory. microSD cards use Serial
Peripheral Interface (SPI) for communication with
the microcontroller.
