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.

Programming with mikroBootloader
Figure 3-2: USB HID mikroBootloader window
step 1 – Connecting mikromedia
01
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.
Microcontroller is preprogrammed with USB HID Bootloader, which
can be used to upload new device firmware. To transfer firmware
.HEX file from a PC to MCU you need to use mikroBootloader USB
HID application, which can be downloaded from:
Upon download, unzip it to desired location and start the mikro-
Bootloader application:

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.

mikroProg Suite™for PIC®Software
Figure 3-10: Main Window of mikroProg Suite™for PIC®programming 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.

The microcontroller can be also
programmed with ICD2®or ICD3®
programmer. These programmers
connects 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 first soldered on the CN5 connector. Then you should plug the ICD2®or ICD3®programmer into it, Figure 3-11.
