基于单片机控制的LED点阵显示屏的设计与仿真

Design and Simulation of Dot-matrix LED Display Based on MCU

LED点阵显示屏以其亮度高、寿命长、视角大、性价比高及面积可定制等优势广泛应用于各种显示场合。以单片机为控制核心,文章设计了一种分辨率为16×128的条型LED显示屏。为了验证设计,运用Proteus软件绘制电路硬件原理图,并通过Keil C51软件编写控制程序,通过2个软件的联合调试来仿真整个设计。整个设计比较实用,控制程序可以针对实际硬件电路进行调整和移植,可以较好地满足中英文及简单图案的显示要求。

Dot-Matrix LED display are widely used in a variety of display applicationswith its high brightness, long life, wide viewing angle, cost-effective, customizable size and other characteristics.By using the Proteus VSM and the KeilC51 compiler, a strip LED screen have a resolution of 16x128 is designed for the simulation.The whole design is very flexible and practical, as the program and hardware circuit can be modified according to the actual situation.
