利用串口实现步进电机的控制

Use Serial Port to Control the Step-motor

用普通微机控制步进电机是常常遇到的事情 ,市场可以找到一些步进电机制板卡 ,但又不得不面对价格昂贵这个事实。对于一些简单的控制 ,完全可以用串口来实现。本文介绍了用 PC机控制有 2个步进电机的双轴系统的执行 ,并通过了试验验证。事实证明 。

Stepmotor controller card can be used to solve the controller of stepmotor, but it can′t solve the fact of expensive cost. This paper introduces how to use serial port to control the stepmotor, and presents an example of controlling two stepmotors. This plan has proved to be effective and simple in small control system, but its cost is contrast to stepmotor controller card.
