资料介绍

基于AT89S52设计一个可以智能改变内容的LED显示屏。首先,给出两种不同的设计方案,简述两种方案的设计思路,并对两种方案的关键硬件进行对比,综合各方面因素,选出最优的方案,并给出原理框图;其次,介绍了LED显示屏的工作原理,并且对显示屏所显示图像质量的依据做出说明;最后,介绍LED驱动扫描芯片的工作原理,并在此基础上,对LED显示单元进行设计,详细介绍电路板上各个电路的作用和接线原理。经实际应用表明系统稳定可靠,效果良好。

In this paper,an intelligent LED screen is designed based on AT89 S52,which can change the content intelligently.Firstly,two different design schemes are given.Then,the design ideas of the two schemes are briefly described,and the key hardware of the two schemes is compared to synthesize various factors.The optimal scheme is selected and the schematic block diagram is given.After that,the working principle of the LED display screen is introduced,and the basis of the image quality displayed on the display screen is explained.Finally,the working principle of the LED driver scanning chip is introduced.On this basis,the LED display unit is designed,and the function and wiring principle of each circuit on the circuit board are in...
