摘 要 近年来随着计算机在社会领域的渗透和大规模集成电路的发展，单片机的应用正在不断地走向深入，由于它具有功能强，体积小，功耗低，价格便宜，工作可靠，使用方便等特点，因此越来越广泛地应用各个领域. 本文的电子钟系统是以单片机（AT89C51）为核心，时钟芯片DS1302、数码管显示驱动芯片MAX7219等元器件组成。具体介绍应用Proteus的ISIS软件进行单片机系统的电子钟设计与仿真的实现方法。该方法既能准确验证所设计的系统是否满足技术要求,又能提高系统设计的效率和质量,降低开发成本,具有推广价值。 关键词：单片机； 时钟芯片 ；数码管显示驱动芯片 ；Proteus；电子钟 Design and Simulation Of electronic clock Based on Single-chip System Qiu Songtang Abstract In recent years, with computers in the infiltration and the development of large-scale integrated circuits. SCM application is steadily deepening, as it has strong function, small size, low power dissipation, low prices, reliable, easy to use features, it is particularly suited to and control of the system, increasingly widely used in various fields. This article describes an electronic bell system is single-chip microcomputer (AT89C51) as the core, the clock chip DS1302, LED display driver chip components, such as MAX7219 component.Describes the application of Proteus's ISIS software of the electronic single-chip system clock to achieve the design and simulation methods in details.The method can not only test the property of the system precisely,but also improve development efficiency and reduce development cost,which values in popularity.
