Based on this method, the accurate control pulses are generated from the PC timer and used for driving the step motor to realize a wide range speed control smoothly.
基于该方案，通过截用PC机系统的定时器资源产生精确定时的控制脉冲，使步进电机实现宽广范围内的速度平滑控制。
Event delay, in milliseconds. If this value is not in the range of the minimum and maximum event delays supported by the timer, the function returns an error.
事件延迟，毫秒。如果这个值不在定时器支持的最小和最大延时之间的话，函数将返回一个错误。
The timing range of the timer can be seen greater than general timer.
从中可以看出它的定时范围要比一般定时器大很多。
