STEPPER MOTOR REFERENCE DESIGN KIT USER’S GUIDE

1. Kit Contents

The Stepper Motor Reference Design Kit contains the following items:

 Stepper Motor Reference Design Board

 Stepper Motor

 Universal AC to DC Power Adapter

 USB Debug Adapter

 USB Cable

 Serial Cable

 Reference Design Kit Tools & Documentation CD

2. Kit Overview

This reference design demonstrates a high-performance stepper motor system using the C8051F300/1. The

reference design provides for both stand-alone demo operation and UART control. The reference design may also

be used as a platform for stepper motor code development.

This User's Guide provides a step-by-step guide for getting your system up and running. Refer to the application

note “AN155: Stepper Motor Reference Design“ for complete documentation of the Stepper Motor Reference

Design.

3. Stepper Motor Reference Design Demonstration

The Stepper Motor Reference Design includes everything you need to set up a stepper motor demonstration.

Connect the stepper motor to the stepper motor control board following the wiring chart for the 42BYG205 motor as

shown in Table 1.

Connect the universal ac/dc power adaptor to the dc supply (P1) on the Stepper Motor Reference Design Board.

Press the Function (FUNC) button on the Stepper Motor Reference Design Board. The motor will turn in one

direction. Notice that the motor accelerates smoothly up to the maximum speed, moves at a constant speed, and

then decelerates smoothly to a standstill. Press the function button again and the motor will turn the other direction.

4. HyperTerminal Demonstration

Start with the Demo Setup above and add an RS-232 cable connection to your computer as shown in Figure 3. The

RS-232 connection is used with a terminal program to provide a basic terminal interface for the stepper motor. If

your PC has USB and does not have a serial port, you may use the Silicon Laboratories CP2102 EK to provide a

virtual COM port connection.

Figure 3. Stepper Motor Reference Design Terminal Setup

Open the HyperTerminal application. The HyperTerminal program may be launched on most Windows XP systems

from the Start Menu:

ProgramsAccessoriesCommunicationsHyperTerminal

Enter any name into the "Connection Description" dialog box is shown in Figure 4. In the "Connect To" dialog box,

choose the COM port corresponding to the Serial connection on your PC. In the Port Settings dialog box select

57600 baud and no flow control. Use the default settings of 8 data bits, no parity, and one stop bit.
