基于单片机的LED显示系统设计(论文10000字)
摘 要
随着社会的不断发展，电子显示屏的应用范围越来越广泛。它作为一个重要的宣传平台，已经受到全社会的普遍认可。单片机是一微型处理器，负责数据的接收、发送和处理工作。显示屏作为单片机一个基本的输出单元，不仅可以显示汉字及各种字符，而且还可以显示图像，甚至是三维立体动画。在日常生活中的用途更为广泛。本文以16×16LED电子显示屏的制作为例，讨论电子显示屏的工作原理，明确单片机是如何控制发光二极管显示汉字的。
本系统运用AT89S51作为数据处理部分，16×16LED电子显示屏为汉字显示部分，通过S51单片机的输入输出口向显示屏上送数，控制在显示屏上显示汉字。电路板上的复位按键，让程序从头开始执行。

Design of Led Display System Based On MCU
Abstract
Along with society's unceasing development, the application scope of the electronic display monitor is more and more widespread. As an important platform, the electronic display monitor has been already received the universal approval from the entire society. The monolithic integrated circuit is a miniature processor, and is responsible for the data receiving, the transmission and the processing. The display monitor took a monolithic integrated circuit basic output unit, not only may demonstrate the Chinese character and each kind of character, moreover also may demonstrate the picture, even is the three dimensional animation. It is more widespread in the daily life use. The paper take 16×16LED the electronic display monitor manufacture as the example, the discussion to electron display monitor principle of work, and make a clear that how the monolithic integrated circuit unit controls the light emitter diode to demonstrate the Chinese character.
The system takes AT89S51 as the data processing partial 16×16LED electron display monitor for the Chinese character display part, delivers the number through the S51 input outlet to the display monitor on, controls demonstrates the Chinese character on the display monitor. On the electric circuit board replacement pressed key, lets the procedure start to hold the front part of a jacket from the beginning.
