“软件就是仪器”，应用LabWindows/CVI实现仪器领域的新革命，可方便的实现对步进电机的数据采集，显示，数字输出，既可以控制单个步进电机，也可以把步进电机组成空间向量进行控制，而且结构简单.运行高效。本文主要讲了对单个步进电机的控制，通过和单片机控制的时比可以看出LabWindows/CVI的优势。

“The soft is The Instrument. Application”, LabWindiws/CVI realize thr new revolution of the instrument . It can make the control of step motor , data processing so on with simplification and high efficiency . At one time , it can control one step motor or three step motor which is made up of a three dimension vector . This paper expatiate thr advantage of thr LabWindows/CVI through comparing the LabWindows/CVI and single chip with one step motor .
