PAGE / NUMPAGES 单片机电子时钟 摘要：在日常生活中，电子时钟与我们密切相关，在很多地方都会用到电子时钟。除了专用的时钟、计时显示牌外，许多应用系统常常也带有实时时钟显示，如各种智能化仪器仪表、工业过程控制系统以及家用电器等。实现电子时钟的方法有多种，通过前面我们对单片机基本理论及相关知识的学习，在这里，要求用单片机为主控制芯片设计一简单的单片机电子时钟。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，因此特别适合于与控制有关的系统，越来越广泛地应用于自动控制，智能化仪器，仪表，数据采集，军工产品以及家用电器等各个领域，单片机往往是作为一个核心部件来使用，在根据具体硬件结构，以及针对具体应用对象特点的软件结合，以作完善。 关键词：电子时钟；单片机；计时 SCM Electronic Clock Abstract:In our daily life, the electronic clock is closely related to the electronic clock which will be used in many places. In addition to a dedicated clock, timing licenses, there are many applications which often with real-time clock display, such as a variety of intelligent instrumentation, industrial process control systems and home appliances. There are many ways to realize the Electronic clock, through the front of learning our SCM basic theory and related knowledge, here, the microcontroller-based control chip design a simple single-chip electronic clock. With the development of computer penetration in the social field and LSI in recent years, the using of microcontroller applications is constantly go deeper, because it has the features of a small size, low power consumption, cheap, reliable, easy to use. Therefore it is particularly suitable for the control of the system, more and more widely used in automatic control, Intelligent instruments, data acquisition, and military products and home appliances, SCM often used as a core component in the structure, according to the specific hardware and software for application-specific object characteristics combined to make perfect.
