摘 要 随着数字电子计算机的广泛应用，单片机的应用也已深入到了社会领域的各个方面。为此选本次毕业设计课题为：基于P89C668单片机的步进电机运动控制系统的研发，P89C668单片机属于．Philips的增强型8051系列。本设计是利用单片机来控制步进电机的运转，通过键扫描，程序的控制来实现步进电机的起、停，正、反转，加、减速的运动状态。本次设计应用到的开发工具是：Protel DXP2004和uVision2，本系统是应用汇编语言进行控制的。 正文中首先简单描述了课题背景，开发环境和需要完成的功能；接着介绍了系统方案设计，其中包括硬件选型和开发工具两部分，论述了本次毕业设计所应用的各种设备的功能及其工作过程，此部分为系统的硬件设计做作准备；最后详细介绍了系统硬件的设计，附有相应的电路图，并给出了系统的硬件设计总图。在正文中还简单描述了增强型8051单片机的电路接口的硬件调试。 关键词：单片机，步进电机，8051  ABSTRACT Along with the digital computer widespread application, the monolithic integrated circuit application also thoroughly arrived social domain each aspect, For this anthology graduation project topic is: Based on the P89C668 Single chip Microcomputer. Stepping Motor movement control system research and development, the P89C668 Single chip Microcomputer belongs to Philips the enhancement 8051 series. This design is controls a Stepping Motor revolution using Single chip Microcomputer, through the key scanning, the procedure control realizes Stepping Motor stops, the reverse, adds the state of motion which, decelerates, This design applies the development kit is Proter DXP2004 andμVision2, this system carries on the control using the assembly language. In the main text first simply described the topic background, the function which the development environment and needs to complete; Then introduced the system plan design, including the hardware shaping and its the work process which this graduation project applies, this part for system hardware design, attaches the corresponding circuit diagram, and has produced the system hardware design assembly drawing. Also simply described the enhancement 8051 Single chip Microcomputer electric circuit connections hardware debugging in the main text. Keyword: Single chip Microcomputer, Stepping Motor, 8051 前 言 本次毕业设计的课题是基于P89C668的步进电机运动控制系统设计，在设计阶段，对三极管，二极管，电阻，电容，发光二极管，P89C系列单片机，光电隔离器，步进电动机驱动器等元器件有了比较好的了解，并拟定了相应的总系统设计。 在本次设计过程中，掌握了基本的集成电路的基本分类方法和功能查找方法，以及工作特性，掌握了实验开发板的基本使用方法，掌握了固件开发集成环境μVision的基本使用方法，对Prot
