Introduction to mikromedia for PIC32®
The mikromedia for PIC32®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 PIC32MX460F512L
microcontroller. The mikromedia for PIC32®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
HID 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.

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.

Programming with mikroBootloader
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:

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 existing microcontroller program will execute.

Connecting mikroProg™to mikromedia™
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.
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.
Page 16
Programming with mikroProg™programmer

Page 17
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

mikroProg Suite™for PIC®software

The microcontroller can
be also programmed
with ICD2®or ICD3®
programmer. These
programmers connects
with mikromedia board
via ICD2 CONNECTOR
BOARD.
In order to enable the ICD2®and ICD3®programmers to be connected to the mikromedia board, 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.

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).
