DEVELOPMENT BOARD

Chapter 6. Getting Started with dsPIC Digital Signal Controllers

6.1 HIGHLIGHTS

This item discussed in this chapter is:

• Initial Setup

6.2 INITIAL SETUP

The following procedure describes how to set up the PICDEM MC LV Development

Board to run with a dsPIC

device.

1. Place the PICDEM MC LV Development Board on a sturdy platform/surface.

2. Confirm that a dsPIC30F2010, dsPIC30F3010 or dsPIC30F4012 is mounted in

the “dsPIC” marked U3 socket.

3. Connect the 24V power supply to J5. DO NOT connect the motor wires to the

board. LED D7 (red) should turn on. If it does not turn on, check the polarity of

the power supply connector. If it is correct and LED D7 does not turn on,

disconnect the power to the board and contact Microchip’s local office or

distributor.

4. Two Application Notes are available for information on running BLDC Motors

using dsPIC devices:

AN957, “Sensored BLDC Motor Control Using dsPIC30F2010

” (DS00957)

AN992, “Sensorless BLDC Motor Control Using dsPIC30F2010

” (DS00992)

AN957 and AN992 have been developed using the PICDEM MC LV Development

Board

. The code available with these Application Notes can be downloaded from

the Microchip web site (www.microchip.com) and will work with the BLDC motor

provided in the application kit. To generate a project and program using MPLAB

ICD 2 In-Circuit Debugger, refer to the “

MPLAB

ICD 2 In-Circuit Debugger

User’s Guide

” (DS51331).

WARNING

Note 1: The PICDEM MC LV Development Board is intended to drive the 3-phase

BLDC motor. Before connecting the motor, make sure that the power

rating of the motor is equal or less than the power rating of the board, as

shown in Appendix B. “Electrical Specifications”. Also, make sure the

jumper settings are correct for the firmware programmed into the target

dsPIC device mounted on the socket. Failure to comply with this warning

could lead to malfunction of the board, the motor and could be hazardous

to the development staff.

2: Before beginning the start-up procedure, complete a visual check of the

board and the motor for connectivity and mechanical damage. If damage

is found, DO NOT power-up the board. Otherwise, you may further

damage the equipment. Contact Microchip’s local office or distributor

immediately.
