摘要
单片微型计算机(Single Chip puter)简称单片机,是指集成在一块芯片上的计算机,它具有结构简单、控制功能强、可靠性高、体积小、价格低等优点。单片机技术作为计算机技术的一个重要分支,广泛的应用于工业控制、智能化仪器仪表、家用电器、电子玩具等各个领域。
近年来随着科技的飞速发展,单片机的应用正在不断地走向深入,同时带动传统控制检测日新月异更新,在实时检测和自动控制的单片机应用系统中,单片机往往作为一个核心部件来使用,仅单片机方面的知识是不够的,还应根据具体硬件结构,以及针对具体应用对象特点的软件结合,加以完善。
本设计通过用汇编语言对8952单片机写程序实现了对8个发光二极管的自如控制,并具有复位和中断功能,另外加上了一组静态数码管以显示流水灯的花样计数。根据设计要求基本达到了预期的目的。
正文首先介绍本课题的背景、研究意义及完成的任务功能;简单描述元器件和方案的论证;系统硬件的工作原理和软件的设计;最后对本设计进行了总结。

Abstract
The single puter, it is to point to integration on a single puter, it is simple in structure, control strong function, high reliability, small volume, low price advantage. Single chip puter as an important branch puter technology, widely used in industrial control, intelligent instruments, home appliances, electronic toys and other fields.
In recent years, with the rapid development of science and technology, the application of SCM is continuously, while driving to the deepening traditional control test rapidly updated, in real-time detection and automatic control of single-chip puter application system, often as a ponent to use, only microcontroller aspects of knowledge is not enough, should according to specific hardware structure, and the view of the specific application object characteristics of bines, perfected.
This design by using assembly language to 8952 microcontroller programming realized to eight light-emitting diodes freely control, and has the reset and interrupt function, with the addition of a group of static digital tube to show water lamp patterns counting. According to the design requirements basic achieve the expected purpose.
The text introduces the background, this topic research significance and plish the mission of function, Simple ponents and scheme of argumentation, The work of system hardware principle and software design; Finally this design was summarized.
