摘要
近年来随着科技的飞速发展,单片机的应用正在不断地走向深入。在实时检测和自动控制的单片机应用系统中,单片机往往是作为一个核心部件来使用,仅单片机方面知识是不够的,还应根据具体硬件结构,以及针对具体应用对象特点的软件结合,加以完善。
本文介绍了基于单片机的数字时钟的设计,详细讨论了它从软件上实现的过程,重点在时钟调整的方式;查询和中断的比较,然后对时钟的精确性和稳定性做了相关的讨论。在文章的最后,给出了采用中断方式实现的数字钟的源程序。
关键字:单片机,数字钟,数据缓冲区,中断,定时
ABSTRACT
Along with science and technology is updating in recent years , the application of MCU is going deeper. In the application of the automatic control and detection of real time, the MCU is used to use as a key parts. But if you
want to design a system , only learn the knowledge of MCU is insufficient . You should perfect the system on the basis of the structure of the hardware and it is link to the characteristic of the application object of the software.
First, in this pape
