LED点阵显示屏作为一种新兴的显示器件,是由多个独立的LED发光二极管封装而成. LED点阵显示屏可以显示数字或符号, 通常用来显示时间、速度、系统状态等。文章给出了一种基于MCS-51单片机的16×16 点阵LED显示屏的设计方案。包括系统具体的硬件设计方案,软件流程图和部分汇编语言程序等方面。在负载范围内, 只需通过简单的级联就可以对显示屏进行扩展,是一种成本低廉的图文显示方案。-Destem as a new kind of display devices, is composed of multiple independent LED light emitting diode encapsulation and into. Destem can display Numbers, or symbols, usually used to display the time, speed, the system state, etc. The paper gives a method based on MCS- 51 SCM 16 x 16 lattice LED display design. Including system design scheme of concrete hardware and software flow chart and part assembly language programs, etc. In load range, just through the simple cascade can expand on screen, is a low-cost graphic display solutions.
