摘 要: 本设计为基于PROTEUS的单片机LED点阵显示屏的仿真设计。由于它方便，醒目，可靠传播信息的手段，在现实生活和生产中有着广泛的应用，对社会经济的发展有着很大的贡献，从而来开发LED点阵显示屏。而且proteus和keil软件在设计，测试和仿真的方面对于单片机的开发是有着很强大的功能的。我们可以在软件中对我们的设计进行仿真，这样做的话既能够节省宝贵的资源而且还可以大大提升我们的工作效率。本设计是由时钟电路，复位电路，电源电路，单片机，显示电路，行驱动电路，列驱动电路等模块组成的。AT89C51单片机作为整个系统的核心控制着各个模块然后再结合程序让点阵显示屏动态地显示出了汉字。 关键词:AT89C51，LED点阵显示屏，单片机，模块 毕业设计外文摘要
Abstract: This design is based on the PROTEUS simulation design of the LED dot matrix display screen. Because it is convenient, smart, reliable means of dissemination of information, has been widely used in the real life and production, has great contribution to the development of social economy, and thus to develop the LED dot matrix display screen. And proteus and keil software for single-chip microcomputer has a strong design, test and simulation function. We can for our design in the software simulation, do so to save valuable resources and can also improve our work efficiency greatly. This design is by the clock circuit, reset circuit, power circuit, microcontroller, display circuit, line driver circuit and column driver circuit module composition and so on. AT89C51 single-chip microcomputer as the core of the whole system controls the various modules and then combined with dynamic program to dot matrix display screen to show the Chinese characters. Keywords: LED dot matrix display screen ， AT89C51 , SCM , Module
