摘要
介绍了一种基于单片机和CPLD联合控制的步进电机控制系统。系统通过单片机发出控制信号来设定电机的转速和方向。CPLD将单片机发出的控制信号转换成电机的实际控制信号,并通过驱动放大电路来实现对步进电机速度和方向的精确控制。系统采用CPLD大大简化了系统的外围硬件电路结构,提高了系统抗干扰性能,缩短了设计周期。
This paper introduces a stepper motor control system based on MCU and CPLD.Microcontroller systen control signals are sent to set the motor speed and direction.CPLD send the control signals into the actual control signal,and amplified through the drive circuit for stepper motor speed and direction of precise control.The system uses CPLD greatly simplifies the system by the external hardware circuit structure to improve anti-interference performance of the system and shorten the design cycle.
