使用单片机控制步进电机(C语言源代码已经在自己板子上烧写过)
题 目：单片机控制步进电机系统
摘 要
很多工业控制设备对位移和角度的控制精度要求较高, 一般电机很难实现, 而步进电机可精确实现所设定的角度和转数。本设计主要是运用51 单片机控制六线4相步进电机系统, 由单片机产生驱动脉冲信号, 控制步进电机以一定的转速向某一方向产生一定的转动角度。同时能够利用单片机实现电机的正、反转及速度控制，并能在数码管上显示出相应的速度。 本文中给出了该系统设计的硬件电路，软件设计，人机交互等。并对各个功能模块进行了详细的说明。主要内容包括以下几个方面：
单片机控制步进电机的一般原理。
电机驱动及控制的实现。
控制系统整体设计以及模块划分说明。
原理图。
代码。
关键词：单片机；步进电机；系统；驱动
Abstract
Many Industrial control equipment have a highly requirement in displacement and angle with control accuracy, the most motor can't carry out .but the step motor can carry out the displacement and angle that you enactmented in accuracy. This design mainly used SCM to control step motor system.The step motor is formed six lines and four phasic.Through SCM generate the drive pulse signal.Control stepper motor through a certain speed in a direction to get a certain degree of rotation angle.
At the same time, It can use SCM to realization of the motor is , reverse and speed control. and showed the speed in the digital tube.
In this paper, given the design of the system hardware circuit,software design, human-computer interaction and so on.and it given the details description of each functional module.the main contents include the following:
(1) The general principles of signal_chip controlling step motor.
(2) The realization of motor driving and controlling
(3) Control system overall design and description module division
(4) Schematic Diagram
(5) Code
Key Words：SCM; stepper motor; system; drive
