1、毕业设计（论文）题目：多变流水灯控制电路的设计学院：电气与电子信息工程学院专业名称：学号：0530220111学生姓名：李文涛指导教师：江玲2008年5月20日摘要本设计是一LED流水灯的设计。整机以美国ATMEL公司生产的40脚单片机AT89C51为核心，介绍了以它为控制系统的LED灯的动态设计和开发过程。通过该芯片控制一个行LED灯按一定顺序亮，文中详细介绍了LED显示的设计思路。单片机控制系统程序采用单片机汇编语言进行编辑，通过编程控制各显示点对应LED阳极和阴极端的电平，就可以有效的控制各显示点的亮灭。当然流水灯一般只是在用芯
2、片做控制时起修饰作用，若只用单片机做流水灯，就不能很好体现单片机的强大功能。这里的流水灯只是单片机应用中的最基础的一方面。LED显示以其组构方式灵活、显示稳定、功耗低、寿命长、技术成熟、成本低廉等特点在车站、证券所、运动场馆、交通干道及各种室内/外显示场合的信息发布，公益宣传，环境参数实时，重大活动倒计时等等得到广泛的应用。经实践证明，该系统显示误差小，性能稳定，结构合理，扩展能力强。关键词：汇编语言；AT89C51单片机；动态显示；LEDABSTRACTThisdesignisLEDflowsthelanternfloateddow
