PC定时器在步进电机速度控制上的应用

Step Motor Speed Control Based on PC Timer

针对步进电机速度精确控制的需要,利用PC定时器实现微秒级精确定时,通过PC并口输出步进电机控制脉冲,在Windows XP操作系统下,借助Compuware Driver Studio驱动开发软件,实现步进电机控制脉冲的精确输出。

According to the request of accurate step control for motor, microsecond timer is realized with the system timer of PC, and pulse signals are transmitted through parallel port. The driver which is responsible for transmitting pulse is open ed up by compuware driver studio on WindowsXP operating system.
