基于单片机的时钟系统设计

I中文摘要基于单片机的时钟系统设计摘 要传统的时钟指针转动是通过上发条的形式控制或通过继电器等多种分立元器件控制，复杂且占用空间大。科学技术不断地进步，生活水平不断地提高，人们对时钟有了更高标准的需求，因此，基于单片机基础的时钟系统设计应运而生，比之传统更精确更直观[3]。 本文主要从硬件和软件设计两个方面介绍了单片机的电子数字时钟的具体实现过程及分析。 本次毕业设计在 STC89C52 单片机的基础上，利用单片机的运算和控制功能，进行信号处理，并采用主要软件模块、系统化 LED 显示模块实现实时显示数字。在软件方面，选用 C 语言编程，实现时钟调节系统。有效处理了生产生活中对计时的超高准确度的需求，所以该课程设计在当今社会中应用十分广泛，遍及生活的每个角落。关键词：单片机;时钟系统 IIAbstractDesign of clock system based on MCUAbstractSingle chip microcomputer is integrated circuit chip. It is a single chip microcomputer system which uses large-scale integrated circuit technology to integrate CPU, ram, ROM, I / O interface, interrupt system and other functions on a single silicon chip. Traditional clock pointer rotation is controlled by winding up or relay, which is complex and takes up a large space. With the development of science and technology and the improvement of living standard, people have more technical requirements on all aspects of clock. Therefore, the design of clock system based on single-chip microcomputer came into being, which is more accurate and intuitive than the traditional.This paper mainly introduces the realization and analysis of the electronic digital clock of single chip microcomputer from two aspects of hardware and software design. On the basis of AT89C51 single chip microcomputer, this graduation design uses the operation and control functions of single chip microcomputer to process signals, and uses main software modules and systematic LED display modules to realize real-time di...
