基于单片机的单色 LED 的点阵控制程序―LED 显示系统讨论 学 生：指导老师：摘 要LED 电子显示屏是利用发光二极管点阵模块或像素单元组成的平面式显示屏幕。他具有发光效率高、使用寿命长、组态灵活、色彩丰富以及对室内外环境适应能力强等优点。并广泛用于公交汽车、码头、商店、学校和银行等公共场合用于信息的发布和广告宣传。自 20 世纪八十年代开始，LED 电子显示屏的应用领域已经遍布了交通、电信、教育、广告宣传等各方面。LED 电子显示屏进展较快，其无论在成本和产生的社会效益等方面都有其独特的优势。文章介绍了基于单片机STC89C51的16 16点阵LED电子显示屏的设计。分别阐述了显示屏显示的基本原理，硬件设计、控制方法及其程序的实现。经过调试和分析，设计的结果能够实现对汉字的静态和动态显示，动态显示的内容有多种方式，同时又可通过上位机更新显示的内容。关 键 词 ： STC89C51 16×16 点 阵 LED 74LS154 74LS595 Microcontroller-based monochrome dot matrix LED control program-LED Display System Student: Chan Wing Instructor: Li Xiuzhi AbstractLED electronic display module is the use of light-emitting diode dot or pixel unit consisting of flat display screens. He has a high luminous efficiency, long life, flexible configuration, rich colors and strong ability to adapt to indoor and outdoor environmentaladvantages. And is widely used in public transport vehicles, terminals, shops, schools and banks and other public places for publishing and advertising information. Since the beginning of the 1980s, LED electronic display applications have been all over the transport, telecommunications, education, advertising and other areas. The rapid development of LED electronic display, which in terms of cost and social aspects such asgeneration has its own unique advantages.This paper introduces the 1616-based microcontroller STC89C51 dot matrix LED electronic display design. The basic principles were displayed on the screen, hardware design, control method and...
