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, audio connector,
MMC/SD card slot, 8 Mbit ash memory, 2x26
connection pads and other. It comes pre-
programmed 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.

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.

step 1 – Connecting mikromedia
01
You can program the microcontroller with bootloader which
is preprogrammed 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:
Upon download, unzip it to desired location and start the
mikroBootloader application:
http://www.mikroe.com/downloads/get/1704/mikro-
bootloader_pic24_usbhid_v210.zip
01 In order to start, connect the USB cable or (if already
connected) press the Reset button on your mikromedia
board. Click the Connect button within 5s to enter the
bootloader mode, otherwise the existing microcontroller
program will be executed.

The microcontroller can be programmed with mikroProg™
programmer and mikroProg Suite™for PIC®software. The
mikroProg™programmer is connected to the development
system via the CN6 connector, Figure 3-9.
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.

Page 17
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 3-10: Main Window of mikroProg Suite™for PIC®programming software

Figure 3-11:
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 3-11.

4. Reset Buttons
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).
Figure 4-2: Frontal reset button
Figure 4-1: Location of additional reset button
You can also solder additional reset button
on the appropriate place at the back side
of the board, Figure 4-1.
