由于单片机技术在各个领域正得到广泛的应用，世界上许多集成电路生产厂家相继推出了各类型的单片机，在单片机家族的众多成员中，MCS-51系列单片机以其优越的性能、成熟的技术及高可靠性和高性能价格比，迅速占领了工业测控和自动化工程应用的主要市场，成为国内单片机应用的主要领域的主流。目前，可用于MCS-51系列的单片机开发的硬件越来越多，与其配套的开发系统、各种软件也也日趋完善，因此，可以极方便地利用现有资源，开发出用于不同目的的各类应用系统。
LED动态扫描显示器是以在MCS-51单片机为基础上扩展的，使其能更方便地运用测控系统中，不仅具有控制方便，组态简单和灵活性大等优点，而可以大幅度提高被测试的技术指标，从而能够大大提高产品的质量和数量。单片机以其功能强、体积小、可靠性高、造价低和开发周期短等优点，称为实时检测和自动控制领域中广泛应用的器件，在工业生产中成为必不可少的器件，尤其是在日常生活中发挥的作用越来越大。本课题论文主要在MCS-51单片机上扩展动态扫描显示器，扩展I/O接口，扩展键盘显示接口。本文以它为列进行介绍，希望能收到举一反三和触类旁通的效果

Because the monolithic integrated circuit technology is obtaining thewidespread application in each domain, in the world many integratedcircuits produced the factory to promote various types monolithicintegrated circuit one after another, in the monolithic integratedcircuit family's multitudinous members, the MCS-51 series monolithicintegrated circuit by its superior performance, the mature technologyand the redundant reliability and the high performance price comparedto, has rapidly seized the industry observation and control and theautomated project application main market, became the domesticmonolithic integrated circuit application the main domain mainstream.At present, may use in the hardware which the MCS-51 series monolithicintegrated circuit develops to be more and more many, if the necessarydevelopment system, each kind of software also also day by dayconsummate, therefore, may extremely conveniently use the existingresources, develops uses in the different goal each ki
