User’s Guide

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. Attempts to break Microchip’s code protection feature may be a violation of the Digital Millennium Copyright Act. If such acts allow unauthorized access to your software or other copyrighted work, you may have a right to sue for relief under that Act.

Information contained in this publication regarding device applications and the like is provided only for your convenience and may be superseded by updates. It is your responsibility to ensure that your application meets with your specifications. MICROCHIP MAKES NO REPRESENTATIONS OR WARRANTIES OF ANY KIND WHETHER EXPRESS OR IMPLIED, WRITTEN OR ORAL, STATUTORY OR OTHERWISE, RELATED TO THE INFORMATION, INCLUDING BUT NOT LIMITED TO ITS CONDITION, QUALITY, PERFORMANCE, MERCHANTABILITY OR FITNESS FOR PURPOSE.

This is the initial released revision of this document.

dsPICDEM™ MCSM

DEVELOPMENT BOARD

USER’S GUIDE

Chapter 1. Introduction

The dsPICDEM MCSM Development Board is targeted to control both unipolar and bipolar stepper motors with no hardware configuration changes. This flexible and cost-effective board can be configured in different ways for use with Microchip’s specialized dsPIC33F Motor Control Digital Signal Controllers (DSCs).

The dsPICDEM MCSM Development Board offers a mounting option to connect either a 28-pin SOIC device or a generic 100-pin Plug-In Module (PIM). The board also has two full-bridge inverters. The hardware is designed in such a way that no hardware changes are necessary for 8-, 6- or 4-wire stepper motors in either bipolar or unipolar configurations. Topics covered include:

•Overview

•Features

• What’s Included

• Reference Documents and Webinars

1.1 OVERVIEW

Figure 1-1 shows a photograph of the dsPICDEM MCSM Development Board. A dsPIC33F device uses the MOSFET driver to drive the two full-bridge inverters that power the motor windings. The board includes various circuitries to perform the following functions:

• Drive two motor windings with the two on-board full-bridge inverters

• Measure feedback and other analog signals (i.e., current, DC voltage,

• Communicate with a host computer or an external device via USB

The dsPICDEM MCSM Development Board supports terminal voltages up to 80V and currents up to 3A. Refer to Appendix B. “Electrical Specifications” for more information.
