MPLAB STARTER KIT FOR

dsPIC

DIGITAL SIGNAL CONTROLLERS

USER’S GUIDE

Chapter 3. Develop an Application

The MPLAB Starter Kit for dsPIC

Digital Signal Controllers may be used with MPLAB

IDE, the free integrated development environment available on Microchip’s website.

MPLAB IDE allows the starter kit to be used as an in-circuit debugger as well as a

programmer for the featured device.

In-circuit debugging allows you to run, examine and modify your program for the device

embedded in the starter kit hardware. This greatly assists you in debugging your

firmware and hardware together.

Special starter kit software interacts with the MPLAB IDE application to run, stop and

single-step through programs. Breakpoints can be set and the processor can be reset.

Once the processor is stopped, the register’s contents can be examined and modified.

For more information on how to use MPLAB IDE, reference the following

documentation:

3.1 INSTALLING THE HARDWARE AND SOFTWARE

To install the hardware:

If you have not already set up the hardware to run the demo, follow these steps:

1. Connect a microphone to socket J9. Connect a headphone to socket J8. Ensure

that potentiometer R56 is set to the factory setting, i.e., the arrow on the

potentiometer points to the arrow on the board.

2. Power up the starter kit by connecting the board to the USB port of a computer.

You should briefly see a pop-up balloon in the system tray (lower right of desktop)

that states (1) new hardware has been found, (2) drivers are being installed, and

(3) new hardware is ready for use. If you do not see these messages and then

the starter kit does not work, try reconnecting the USB. If this does not work, see

Section 3.8 “Troubleshooting”.

3. When powered up, the application will repeatedly play back an introductory

message.

To install the software:

Run CD-ROM enclosed with the starter kit and install software as directed.
