本文阐明用单片机控制LED显示屏进行显示的方法，对LED显示模块单元如何进行行列信号控制及信号传输中的驱动问题进行了研究。LED显示屏作为一种重要的显示器件在实际中具有广泛的应用。本文以AT89C52芯片为控制芯片，分别采用具有移位锁存功能的74HC595和4-16线译码器74154进行列控制和行控制，最终实现16X64点阵的显示器自右向左进行移动显示。使用Proteus设计电路图仿真，keil中编译后联调来模拟实际显示效果。同时介绍了LED显示屏和单片机的发展情况，介绍了控制芯片的具体结构和功能，用于模拟仿真和字模提取的软件的使用方法，并按照要求设计电路图和流程图，使用汇编语言进行了编程。讨论了单片机控制系统中关键的数据处理以及发送问题，结果表明采用并行数据输入、串行数据输出的专用电路可大大减少CPU的辅助时间，提高数据的发送速度。
This article stated MCU control LED display to show the way, the LED display modules ranks of how to control and transmit signals in the driving issue was studied. LED display as an important display in practice a wide range of applications. In this paper, AT89C52 chip to control the chip, by using a function of displacement latch 74 HC595 and 4-16 line decoder 74,154 for out control and control line, the ultimate realization of 16 X64 since the dot-matrix display shows right to left to move. Proteus circuit design using simulation, keil compiled after the FBI to simulate the actual effect. At the same time on the LED display and the development of SCM, introduced a chip control the specific structure and functions for simulation and Zimo from the use of the software, and in accordance with the requirements of design schematics and diagrams, use the compilation of language The programming. SCM discussed the control system of critical data processing and delivery problems, results sh
