PractiSPIN™.spmd demonstration system

configuration and set up guide

Introduction

PractiSPIN™.spmd is a demonstration system that can be used with several 
STMicroelectronics stepper motor driver modules. 

The system consists of a graphical user interface (GUI) program which runs on an IBM-PC 
under windows, a common ST7-based interface board that communicates with the PC and 
the PractiSPIN™.spmd software via a serial COMM port, and a module-specific 
demonstration board (target board) that connects to the ST7 interface board via a standard 
34-pin ribbon cable interface, as shown in 

Figure 1

.

The module demonstration board connects to the motor and to a user-supplied DC power 
supply generally in the range of 12 to 48 VDC, plus a logical supply rated 5 VDC.

The PractiSPIN™.spmd system is designed to operate the target module under the control 
of the PractiSPIN™.spmd software.
