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.

DOCUMENT REVISION HISTORY

Revision A (June 2008)

This is the initial release of the PIC32MX USB Starter Board User’s Guide.

PIC32MX USB STARTER

BOARD USER’S GUIDE

Chapter 1. Introducing the PIC32MX USB Starter Board

1.1 INTRODUCTION

Thank you for purchasing the Microchip T echnology PIC32MX USB Starter Board. This board provides a low-cost, modular development system for Microchip’s new line of 32-bit microcontrollers.

The starter board comes pre-loaded with dem ons trati on softwar e 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 USB Starter Board 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 The preprogrammed example code on the PIC32MX MCU is available via download.

All project files have been included, so that the code may be used directly to restore the PIC32MX MCU on the starter board 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. Refer to Section 2.4 for download and installation instructions.

1.3 KIT CONTENTS

The PIC32MX USB Starter Board contains the following items:

• PIC32MX USB Starter Board

• USB Mini-B to full-sized A cable – USB debug cable to debug and power the board

• USB Micro-B to full-sized A cable – PIC32 USB cable to communicate with the PIC32 USB port

If you are missing any part of the kit, contact a Microchip sales office for assistance. A list of Microchip offices for sales and service is provided on page 36.

PIC32MX USB Starter Board User’s Guide

1.4 PIC32MX FUNCTIONALITY AND FEATURES

A representation of the layout of the PIC32MX USB Starter Board is shown in Figure 1-1. The board includes these key features, as indicated in the diagram:

1. PIC32MX460F512L 32-bit microcontroller

2. Green power-indicator LED

3. Regulated +3.3V power supply for powering the starter 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 indicato r LED s

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

11. USB Type A receptacle connectivity for PIC32MX Host based Applications

12. USB Type Micro-AB receptacle for OTG and USB Device connectivity for PIC32MX OTG/Device based Applications (on the underside on board)

13. USB Host and OTG power supply for powering PIC32MX USB applications.

Note 1: To power Rev B boards, the USB debug cable must be connected to a

USB port on the host PC.

2: When running USB device applications, open the jumper JP2 to prevent

possibly back-feeding voltage onto VBUS from one port on the host to another (or from one host to another).

operating systems.)

2.4 INSTALLING THE PIC32MX USB STARTER BOARD SOFTWARE

Starter board software and installation instructions are available on the Microchip.com web site at the following URL: http://www.microchip.com/PIC32USBboard. The web page will guide you through installation and setup of MPLAB IDE, MPLAB C32 C Compiler, and the demo projects. The page also provides links to other technical documents. After completing the online installation instructions, continue to the next section in this document.

PIC32MX USB Starter Board User’s Guide

2.5 USING THE PIC32MX USB STARTER BOARD OUT OF THE BOX

Install software (instructions in section 2.4) before connecting the board to the host PC. The PIC32MX USB Starter Board 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 ( device and is ready for immediate use.

2.5.1 How to Play the Game

When the USB debug cable is plugged into the starter board’s Mini-B (debug) receptacle, 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 the game. After a brief pause, you can press any switch to start a new game.

If you launch MPLAB IDE and connect to the starter board while the game is running, the game will stop. Further, if you perform a debug or program operation from MPLAB IDE, the demo application will be replaced with the current MPLAB project application. However, the game can be reloaded onto the starter board by opening the file

simon_says_demo.mcw from c:\Program Files\Microchip\pic32_solutions\ simon_says_demo

The preprogrammed example code on the PIC32MX has been included in the PIC32MX USB Starter Board demo-projects download file located at the following URL:

http://www.microchip.com/PIC32USBboard. 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.
