USER’S GUIDE ADDENDUM FOR PIC32MX

Chapter 1. Programming Tutorial for PIC32MX

1.1 INTRODUCTION

This chapter is a self-paced tutorial to get you started using the Explorer 16 Develop-

ment Board with a PIC32MX Plug-In Module (PIM).

1.2 HIGHLIGHTS

Items discussed in this chapter include:

• Installing Explorer 16 with PIC32MX Software and Documentation

• Using the Explorer 16 Out of the Box

• Explorer 16 Development Board Demonstration Programs

• Tutorial Overview

• Creating the Project

• Building the Code

• Programming the Device

• Tutorial Program Operation

1.3 INSTALLING EXPLORER 16 WITH PIC32MX SOFTWARE AND

DOCUMENTATION

The Explorer 16 Development Board PIC32MX CD contains the Microchip MPLAB

IDE integrated development environment and MPLAB

C32 C Compiler, the

Explorer 16 Development Board User’s Guide Addendum, and the files and software

to create the tutorial project. Insert the disc into your CD drive and an automatic

installation application will guide you through installation of the tools and documents.

1.4 USING THE EXPLORER 16 OUT OF THE BOX

Although intended as a development platform, the Explorer 16 board can also be used

directly from the box as a demonstration board for PIC32MX devices. The program

(

UartBasicLab.hex) discussed in Section 1.11 “PIC32MX Tutorial Program Opera-

tion” is preprogrammed into the PIC32MX PIM and is ready for immediate use.

To get started with the board:

1. For Explorer 16 boards without a permanently mounted PIC32MX device: care-

fully remove the mounted PIM and install the PIC32MX360F512L PIM in its place

with the notched corner of the PIM oriented to the upper-left corner of the board.

2. Verify that switch S2 is set in the “PIM” position.

3. Verify that the jumper on JP2 is installed (to enable the LEDs).

4. Apply power to the board (9 VDC) at power input J2.

For information on acceptable power sources, see Appendix A. “Explorer 16

Development Board Schematics”.

Explorer 16 Development Board User’s Guide Addendum for PIC32MX

1.5 EXPLORER 16 DEVELOPMENT BOARD DEMONSTRATION PROGRAM

The CD contains a sample demonstration program for the PIC32MX360F512L device.

It may be used with the included PIC32MX PIM by reprogramming the device using

MPLAB

REAL ICE™ in-circuit emulator.

The example code preprogrammed on the PIM is also included on the Explorer 16 CD.

All project files have been included, so that the code may be used directly to restore

the PIM to its original state for cases in which the PIM is programmed for another appli-

cation. It is also useful if you would like to use the tutorial code as a platform for further

experimentation.

1.6 TUTORIAL OVERVIEW

The tutorial in this chapter demonstrates features of the MPLAB IDE and REAL ICE as

they are used with the Explorer 16 Development Board. As presented, it is designed

for use with the PIC32MX360F512L specifically. However, the same procedures and

toolsuites can also be used with other PIC32MX devices.

The PIC32MX tutorial project demonstrated here,

UartBasicLab.mcp, is written in C

for the MPLAB C32 C compiler. The program displays the build date and time to the

Microsoft Windows

HyperTerminal on a personal computer (PC) via UART. The pro-

gram also accepts user input from the HyperTerminal. The UartBasicLab program is

described in more detail in Section 1.11 “PIC32MX Tutorial Program Operation”.

After completing this tutorial, you should be able to complete the following tasks:

• Create a project using the Project Wizard

• Set the Configuration bits, and compile and link the code.

• Set up MPLAB IDE integrated development environment to use the MPLAB REAL

ICE in-circuit emulator

• Program the PIC32MX360F512L with the MPLAB REAL ICE in-circuit emulator

2. From the menu bar, click File >Close Workspace

to close any workspace that

might be open.

3. Click Project > Project Wizard...

to start the wizard.

4. From the Welcome screen, click Next > to display the Project Wizard – Step One:

dialog window (Figure 1-1).

FIGURE 1-1: SELECTING THE DEVICE

1.7.1 Select the Language Toolsuite

FIGURE 1-2: SELECTING THE TOOLSUITE

1. From the Active Toolsuite drop-down list, select “Microchip PIC32 C-Compiler

Toolsuite”. This toolsuite includes the assembler and linker that will be used.

If Microchip PIC32 C-Compiler is not available in the list, check the “Show all

installed toolsuites” box and click Help! My Suite Isn’t Listed.

2. In the Toolsuite Contents combo box, select “MPLAB C32 C Compiler

(pic32-gcc.exe)”

3. Click Next >.

The Project Wizard – Step Three: dialog box displays, as shown in Figure 1-3.

1.7.2 Name Your Project

FIGURE 1-3: NAMING YOUR PROJECT

1. Select Create New Project File, click Browse... and navigate to

C:\Program Files\Microchip\pic32_solutions\labs\uart_basic_lab

to place your project and name the project “UartBasicLab”.

C:\Program Files\Microchip\pic32_solutions\labs\uart_basic_lab

is the default location for the project. The folder was created and the source files

were copied during the initial installation.

2. Click Next > to continue.

The Project Wizard – Step Four: dialog displays, as shown in Figure 1-4.

Explorer 16 Development Board User’s Guide Addendum for PIC32MX

1.8 BUILDING THE PROJECT

1.8.1 Set the Configuration Bits

Before building the project, the configuration bits should be set properly. In this example

the configuration settings are mentioned in the source file.

Perform the following steps to set the configuration bits:

1. From the menu bar, click Configure > Configurations Bits...

2. In the configuration settings window (Figure 1-6), check the box “Configuration

Bits set in code” to ensure that the settings are taken from the source file.

FIGURE 1-5: SETTING CONFIGURATION BITS

1.8.2 Make the Project

From the menu bar, click Project > Make to build the project.

Monitor the progress of the build in the Output window, as shown Figure 1-6.

When the “BUILD SUCCEEDED:” message displays, you are ready to program the

device.

1. Click the “Program” icon (Figure 1-7) in the MPLAB REAL ICE in-circuit emulator

window to program the device.

FIGURE 1-7: PROGRAM ICON IN MPLAB

REAL ICE™ WINDOW

A Programming Warning window (Figure 1-8) is displayed to warn you about

overwriting the memory.

2. Click Yes.

FIGURE 1-8: PROGRAMMING WARNING WINDOW

Monitor the Output window (Figure 1-9) for progress as the device is programmed. A

verification will notify you that the programming and verification is complete.

1.11 PIC32MX TUTORIAL PROGRAM OPERATION

The PIC32MX Tutorial is a UART-based program that communicates with a PC through

a UART interface. The program responds to the user input. The program flow chart is

shown in (Figure 1-13).

If the user input choice is ‘e’ or ‘E’, the program prompts for input of a character string

that does not exceed 256 characters. The string is terminated by pressing the Enter key

in the HyperTerminal window. This string will be printed back to the HyperTerminal win-

dow. If the choice is ‘x’ or ‘X’, it leaves the main loop and terminates the program. Any

invalid input will display an error message in HyperTerminal.

The program includes the peripheral library,

plib.h, to facilitate UART functionality.
