Based on MCU stepping motor control   Abstract Stepping motor is a will convert electrical pulses of mechanical and electronic linear displacement Angle or actuator, whenever enter an electrical impulses when it was turned a fixed Angle, pulse lasted for input, motors will keep turning, it is used in digital control system of actuators. With the development of science and technology, stepping motor running accuracy is constantly upgrading. Control method are constantly changeable and diversification, so in many fields been widely used. Stepping motor control is simple, accurate positioning, but traditional pulse driven approach, this paper puts forward portability bad single-chip microcomputer control system in place of the pulse generator and pulse splitter, with software method generates control pulse, through software programming can set arbitrary stepping motor speed, rotation Angle, the rotation frequency and control the stepper motor running state. To simplify control circuit, reduce production cost and improve the operation of the system efficiency and flexibility. Based on this, advances stepping motor program control hardware interface circuit and program flow chart and C language program. This paper is to design a set of hardware system is simple, economy, but the function is relatively complete, adaptable, convenient operation, the electronic technology to organic, a single chip microcomputer technology, motor control techniques are combined to stepping motor control system. This paper mainly describes the working principle of stepper motor, and then put forward by microcontroller primarily controller hardware design of the whole system, on the basis of each module of the circuit detailed design, then expounds the stepping motor control software development processes and program design Keywords:   microcontroller,  stepping motor,  machine control   目  录   摘  要... 1 目  录... 4 一 单片机性能及概述... 6 1.1 单片机的概念... 6 1.2、单片机的特点... 6 1.3、单片机的用途... 7 1.4、AT89C51单片机... 7 二 步进电机... 10 2.1 步进电机的概述... 10 2.2步进电机常识... 10 2.3步进电机的选用及控制技术... 11 2.4 步进电机动态指标及术... 13 2.5、驱动控制系统组成部分... 15 三 硬件接口电路... 15 四 软件分析... 17 4.1主函数监控模块... 17 4.2键盘扫描及处理模块... 18 4.3控制信号产生模块... 18 五 调试结果分析... 20 致  谢... 21 参考文献... 22 附录：程序... 23     [资料来源：http://THINK58.com]
