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.”

Code protection is constantly evolving. We at Microchip are committed to continuously improving the code protection features of our products. Attempts to break Microchip’s code protection feature may be a violation of the Digital Millennium Copyright Act. If such acts allow unauthorized access to your software or other copyrighted work, you may have a right to sue for relief under that Act.

Chapter 1. Introducing the PIC32MX Starter Kit

1.1 INTRODUCTION

Thank you for purchasing the Microchip Technology PIC32MX Starter Kit. This kit provides a low-cost, modular development system for Microchip’s new line of 32-bit microcontrollers.

The Starter Kit comes pre-loaded with demonstration software for the user to explore the new features of the PIC32MX. It is also expandable through a modular expansion interface, which allows the user to extend its functionality. The PIC32MX Starter Kit also supplies on-board circuitry for full debug and programming capabilities.

1.2 HIGHLIGHTS

This chapter covers the following topics:

• Kit Contents

• PIC32MX Functionality and Features

• Using the PIC32MX Starter Kit Out of the Box

• PIC32MX Demonstration Program

The preprogrammed example code on the PIC32MX MCU has been included on the PIC32MX Starter Kit CD-ROM for future reference. All project files have been included, so that the code may be used directly to restore the PIC32MX MCU on the Starter Kit 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.

1. PIC32MX360F512L 32-bit microcontroller

2. Green power-indicator LED

3. Regulated +3.3V power supply for powering the Starter Kit board via USB or expansion board

4. On-board crystal for precision microcontroller clocking (8 MHz)

5. USB connectivity for on-board debugger communications

6. PIC18LF4550 USB microcontroller for on-board debugging

7. Orange Debug indicator LED

8. Three push-button switches for user-defined inputs

9. Three user-defined indicator LEDs

10. Connector for connecting various expansion boards (on the underside of board)

For additional details on these features, refer to Chapter 4. “PIC32MX Starter Kit Hard-

ware”.

Introducing the PIC32MX Starter Kit

1.5 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 in the PIC32MX360F512L device (i.e., simon_says_demo.hex) and is ready for immediate use.

1.5.1 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 to choose the level of game difficulty, SW1-SW3 (SW3 is the eastest, 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 Simon game can be reloaded onto the Starter kit by opening the simon_says_demo.mcw file from the c:\Program Files\Microchip\pic32_solutions\ simon_says_demo directory.

1.6 INSTALLING THE PIC32MX STARTER KIT CD

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 necessary documents.

1.7 PIC32MX DEMONSTRATION PROGRAM

The preprogrammed example code on the PIC32MX has been included on the PIC32MX Starter Kit CD-ROM for future reference. 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.
