Programming with bootloader
For programming, microcontroller use bootloader program which
is preinstaled in to MCU memory. To transfer .hex le from a PC to
MCU you need bootloader softwer (ds30 Loader) which can be
downloaded from:
After software is downloaded uzip it to desired location and start
ds30 Loader software.

Programing with mikroProg™
programmer
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 4-12.
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.
Figure 4-12:
connecting mikroProg

Page 18
Page 19
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 4-13: Main Window of mikroProg Suite for PIC programming softwaer

Figure 5-1: 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 4-15. Then you should plug in the
ICD2 or ICD3 programmer into it as shown in gure 4-14.
