基于单片机的16*16点阵的滚动显示

摘要  本文的设计是基于单片机系统的基本模块的一部分。LED 点阵电子显示屏是集微电子技术、计算机技术、信息处理技术于一体的大型显示屏系统。它以其色彩鲜艳，动态范围广，亮度高，寿命长，工作稳定可靠等优点而成为众多显示媒体以及户外作业显示的理想选择。同时也可广泛应用到军事、车站、宾馆、体育、新闻、金融、证券、广告以及交通运输等许多行业。本次设计的点阵显示屏主要是通过单片机直接控制行扫描，然后用74LS138来控制列扫描。这个设计的软硬件都成功通过了PROTEUS的仿真调试。

Based on SCM 16*16 LED rolling display design

Institute of Physical and XXXXXXl InformationXXXXX Normal University

Abstract: The design of this article is based on a part of the basic module SCM（Single-Chip-Microcomputer）system. LED electronic display screen is a large system which combined with micro-electronic technology and computer technology and information processing technology. It has become the ideal choice of numerous display media and out-door jobs display because of its advantages, including bright-colored flavor, wide dynamic state range, high brilliance, long life-span and stable and reliable work and so on. At the same time, it would be widely used in military affairs, stations, hotels, sports, news, finances, bonds, ads and traffic transportations etc. This design is mainly directly controlled by SCM in order to achieve row-scanning and the column-scanning achieved by the 74LS138.This design of hardware and software modules pass the PROTEUS simulation debugging successfully.

Key words: SCM; LED; rolling display
