1.5 USING THE EXPLORER 16 OUT OF THE BOX

Although intended as a development platform, the Explorer 16 board may also be used directly from the box as a demonstration board for PIC24 and dsPIC33F devices. The programs discussed in Chapter 3. “Explorer 16 Tutorial Programs” are preprogrammed into the sample device PIMs (i.e., PIC24ExplDemo.hex for the PIC24 device and dsPIC33ExplDemo.hex for the dsPIC33F device) and are ready for immediate use.

To get started with the board:

1. For Explorer 16 boards without a permanently mounted PIC24FJ device: verify that the PIC24FJ128GA010 PIM is correctly installed onto the board. If you want to use the dsPIC dsPIC33F PIM in its place. For all PIMs, be certain to align the PIM so the notched corner marking is oriented in the upper left corner.

2. For Explorer 16 boards without a permanently mounted PIC24FJ device: verify that switch S2 is set in the “PIM” position. For Explorer 16 boards with a permanently mounted PIC24FJ device: verify that switch S2 is set in the “PIC” 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”.

Refer to Chapter 3. “Explorer 16 Tutorial Programs” for details on the demonstration code operation.

PIC24FJ128GA010

1.6 EXPLORER 16 DEVELOPMENT BOARD DEMONSTRATION PROGRAMS

The preprogrammed example code on the PIMs has been included on the Explorer 16 CD-ROM for future reference. All project files have been included, so that the code may be used directly to restore a PIM to its original state (i.e., if the sample device has been reprogrammed with another program), or so the user may use the tutorial code as a platform for further experimentation.

In addition, the CD-ROM contains sample demonstration programs for both PIC24 and dsPIC33F family devices. Separate demo source code (as files in C) and compiled code files (in Hex) are provided for each family. These may be used with the included PIC24 and dsPIC33F PIMs by reprogramming the devices using MPLAB ICD 2.

Chapter 2. Explorer 16 Programming Tutorial

2.1 INTRODUCTION

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

2.2 HIGHLIGHTS

Items discussed in this chapter include:

• Tutorial Overview

• Creating the Project

• Building the Code

• Programming the Device

2.3 TUTORIAL OVERVIEW

The tutorial in this chapter demonstrates the main features of the MPLAB IDE and MPLAB ICD 2 as they are used with the Explorer 16 Development Board. As presented, it is designed for use with the PIC24FJ128GA010 specifically. However, the same procedures and toolsuites can also be used with PIC24H or dsPIC33F devices.

The PIC24 tutorial project demonstrated here, PIC24ExplDemo.mcp, is written in C for MPLAB C30. The program displays PIC24 features on the alphanumeric LCD, and also displays voltage, temperature and date/time as the various buttons are pressed. Described with the PIC24 project is the dsPIC device tutorial, Example1_RTC_LED_ADC.mcp. It is also written in C for MPLAB C30. The program displays voltage and current time, updating the display on command. Both programs are described in more detail in Chapter 3. “Explorer 16 Tutorial Programs”.

For either project, the source file (PIC24ExplDemo.c or main_rtc.c for PIC24 or dsPIC33F, respectively) is used with a linker script file (p24fj128ga010.gld or

p33fj256gp710ps.gld) and header file (p24fj128ga010.h or p33fj256gp710ps.h) to form a complete project. While these simple projects use a

single source code file, more complex projects might use multiple assembler and compiler source files, as well as library files and precompiled object files.

Upon completing this tutorial, you should be able to:

• Create a project using the Project Wizard

• Assemble and link the code and set the Configuration bits

• Set up MPLAB IDE to use the MPLAB ICD 2

• Program the chip with the MPLAB ICD 2

There are three steps to this tutorial:

1. Creating a project in MPLAB IDE.

2. Assembling and linking the code.

3. Programming the chip with the MPLAB ICD 2.
