摘 要
数字钟已成为人们日常生活中必不可少的必需品，广泛用于个人家庭以及办公室等公共场所，给人们的生活、学习、工作、娱乐带来极大的方便。由于数字集成电路技术的发展和采用了先进的石英技术，使数字钟具有走时准确、性能稳定、携带方便等优点，它还用于计时、自动报时及自动控制等各个领域。尽管目前市场上已有现成的数字钟集成电路芯片出售，价格便宜、使用也方便，但鉴于单片机的定时器功能也可以完成数字钟电路的设计，因此进行数字钟的设计是必要的。在这里我们将已学过的比较零散的数字电路的知识有机的、系统的联系起来用于实际，来培养我们的综合分析和设计电路，写程序、调试电路的能力。
单片机具有体积小、功能强可靠性高、价格低廉等一系列优点，不仅已成为工业测控领域普遍采用的智能化控制工具，而且已渗入到人们工作和和生活的各个角落，有力地推动了各行业的技术改造和产品的更新换代，应用前景广阔。
关键字：单片机，数字时钟。
Abstract
Digital clock has become an indispensable necessities in People's Daily life, widely used in personal family and office and other public places, to people's life, study, work, entertainment, bring great convenience. Due to the development of the digital integrated circuit technology and adopts the advanced quartz technology, walking make digital clock has advantages of accurate, stable performance, easy to carry, it is also used in timing, automatic feed and automatic control and other fields. Although already on the market at present the ready-made digital clock chip for sale, cheap, use is convenient, but in view of the single chip microcomputer timer function also can complete the design of the digital clock circuit, therefore is necessary for the design of digital clock. Here we will have learned more fragmented knowledge of digital circuit of the organic link, the system used in practice, to develop our comprehensive analysis and circuit design, programming, debugging circuit ability.
SCM has small volume and powerful function, high reliability, low price and a series of advantages, not only has become widely used in the field of industrial measurement and control intelligent control instruments, and has penetrated into every corner of the people work and life, effectively promote the industry's technological transformation and upgrading of products, the wide prospect of application.
Keywords: Single chip microcomputer,Digital clock.
