Note the following details of the code protection feature on Microchip devices:
•
Microchip products meet the specification contained in their particular Microchip Data Sheet.
•
Microchip believes that its family of products is one of the most secure families of its kind on the market today, when used in the
intended manner and under normal conditions.
•
There are dishonest and possibly illegal methods used to breach the code protection feature. All of these methods, to our
knowledge, require using the Microchip products in a manner outside the operating specifications contained in Microchip’s Data
Sheets. Most likely, the person doing so is engaged in theft of intellectual property.
•
Microchip is willing to work with the customer who is concerned about the integrity of their code.
•
Neither Microchip nor any other semiconductor manufacturer can guarantee the security of their code. Code protection does not
mean that we are guaranteeing the product as “unbreakable.”

INSTALLING THE PIC32MX STARTER KIT CD
The default PIC32MX Starter Kit installation directory is:
c:\Microchip Starter Kits\PIC32 Starter Kits
Note, throughout this document, the following phrase “[install directory]” refers
to this default installation, c:\Microchip Starter Kits, or a directory selected by the
user during the time of installation.
The starter kit CD-ROM contains the MPLAB IDE, MPLAB C32 C Compiler tools, code
examples, sample projects, technical documentation, a getting started tutorial, and this
PIC32MX Starter Kit User’s Guide. When the CD is placed into your CD drive, an
automatic installation application will guide you to install the tools and relevant
documents.
1.6
USING THE PIC32MX STARTER KIT OUT OF THE BOX
The PIC32MX Starter Kit may be used directly from the box as a demonstration board
for the PIC32MX device. The PIC32MX is preprogrammed with the classic “Simon
Says” game (simon_says_demo.hex) in the PIC32MX360F512L device and is ready
for immediate use.
1.6.1
How to Play the Game
When the USB cable is plugged into the starter kit, the three LEDs start blinking to
indicate the start of a new game. Begin the game by pressing one of the switches,
SW1-SW3, to choose the level of game difficulty. SW3 is the easiest, SW1 is the
hardest. The goal is to imitate the light patterns as long as you can, without getting
frazzled. Ultimately, you will make a mistake and all of the LEDs will light up to signal
the end of a game. After a brief pause, you can press a switch again to start a new
game.
If the starter kit is connected to the MPLAB IDE, the game stops. It will be replaced by
the MPLAB IDE project that you select when the program button is pressed. The game
can be reloaded onto the starter kit by opening simon_says_demo.mcw from the
following directory:
[install directory]\PIC32 Starter Kits\simon_says_demo
1.7
PIC32MX DEMONSTRATION PROGRAM
The preprogrammed example code on the PIC32MX has been included as part of the
PIC32MX Starter Kit installation. All project files have been included, so that the code
may be used directly to restore a PIC32MX to its original state (i.e., if the sample device
has been reprogrammed with another program) or so you can use the tutorial code as
a platform for further experimentation.

PIC32MX Starter Kit Tutorial
The tutorial program includes the Debug Print Library, which facilitates print functionality. A peripheral library header file for flashing the LEDs is also included. The header
file for print functionality is db_utils.h.
Depending on the macro definition given in the print header file, the debug print macros
will be expanded. The print functionality in the tutorial is routed to the Output window
on the MPLAB PIC32MX tab in the interface window. In order to achieve this, the
macro definition “PIC32_STARTER_KIT” is added to the MPLAB C Compiler for PIC32
options.
As the program runs, the Output window (Figure 2-14) tracks the progress.
FIGURE 2-14:

CREATING A NEW PROJECT
The first step is to create a project and a workspace in the MPLAB IDE. Typically, there
is a single project per workspace.
A project contains the files needed to build an application (i.e., source code, header
files, library, etc.), and their corresponding build options.
A workspace contains one or more projects, information on the selected device,
debug/programmer tool, and MPLAB IDE configuration settings.
MPLAB IDE contains a Project Wizard to help create a new project.
You will perform the following tasks as you create a new project:

USER’S GUIDE
Chapter 4. PIC32MX Starter Kit Hardware
4.1
INTRODUCTION
This chapter describes the hardware features of the PIC32MX Starter Kit.
4.2
HARDWARE FEATURES
The key features of the PIC32MX Starter Kit are listed below. They are presented in the
order given in Section 1.4 “PIC32MX Functionality and Features”. You can refer to
Figure 1-1 on page 8 for their locations on the board.
4.2.1
Processor Support
The PIC32MX Starter Kit is designed with a permanently mounted (i.e., soldered)
PIC32MX360F512L processor.
4.2.2
Power Supply
There are two ways to supply power to the PIC32MX Starter Kit:
• USB bus power connected to J1.
• An external application board with a regulated DC power supply that provides +5V
can be connected to the J2 application board connector that is provided on the
bottom side of the board.
Note:
The basic PIC32MX Starter Kit does not include an application board and
is intended to be USB-bus powered.
One green LED (D3) is provided to show that the PIC32 microcontroller is powered up.
4.2.3
USB Connectivity
The PIC32MX Starter Kit includes a PIC18LF4550 USB microcontroller, which provides
both USB connectivity and support for protocol translation. The PIC18LF4550 is
hard-wired to the PIC32MX device to provide two types of connectivity:
• I/O pins of PIC18LF4550 to ICSP™ pins of PIC32MX
• I/O pins of PIC18LF4550 to JTAG pins of PIC32MX
The PIC32MX Starter Kit currently uses the JTAG pins of the PIC32MX device for
programming and debugging.

DS61144D-page 35
PIC32MX Starter Kit User’s Guide
4.2.4
Switches
Push-button switches provide the following functionality:
• SW1: Active-low switch connected to RD6
• SW2: Active-low switch connected to RD7
• SW3: Active-low switch connected to RD13
The switches do not have any debounce circuitry and require the use of internal pullup resistors; this allows you to investigate debounce techniques. When Idle, the
switches are pulled high (+3.3V). When pressed, they are grounded.
4.2.5
LEDs
The LEDs, RD0 through RD2, are connected to PORTD of the processor. The PORTD
pins are set high to light the LEDs.
4.2.6
Oscillator Options
The installed microcontroller has an oscillator circuit connected to it. The main oscillator
uses an 8 MHz crystal (Y2) and functions as the controller’s primary oscillator. Use of
an external crystal is not required for PIC32 designs. Your design may use the internal
oscillator, if desired.
The PIC18LF4550, at the heart of the USB subsystem, is independently clocked and
has its own 8 MHz crystal (Y1).
4.2.7
120-Pin Modular Expansion Connector
The PIC32MX Starter Kit demo board has been designed with a 120-pin modular
expansion interface, which allows the board to provide basic generic functionality now,
as well as easy extendability to new technologies as they become available.
