摘要
本文介绍一种以INTEL8031单片机为核心控制数千个LED数码管的大屏幕数据显示屏的设计,它可用于银行利率,股票行情,以及厂矿企业生产报表的实时显示,通过将显示屏控制板并联在RS232标准串行通讯线上可实现选址通讯,从而达到在PC机上控制和操作多个大屏幕显示屏。本文给出了一种巧妙的设计方案,它具有软硬件结构简单,控制程序设计方便等特点。
This article introduces a kind of design of a big - screen digital display, with its key INTEL8031 single chip microcomputer to control several thousands of LED digital tubes. It can be used for realtime display of bank interest rate, the stock market and the produce report forms of the industrial enterprices. It can carry out selecting communications through a parallel connection of the display control circuit to the RS232 standard series communication lines and so to control and operate the several big-sereen displays in the personal computer. This article provides you with a clever program of design, which has the advantages of its simple buildup with the soft and hard wares and its easy design of the controlling procedure.
