摘 要
单片机主要是作为核心部件来使用,根据具体硬件结构,结合软件根据具体应用对象的特点,进行改进。在本文中,主要内容是采用单片微机接口技术来设计的电子时钟,使用数码管来实现时钟定时,让通过LED数码管显示的时钟信号,并且还可以通过独立的改性键,可以实现精确的计时,当以数字形式显示的时间分秒;小时的计时要求为满24回1,分秒的计时为60进制进位。时间的校正;定时控以及仿无线电报时的时间;在上方显示日期星期。
关键词:单片机数字钟LED数码管
ABSTRACT
Currently microcontroller penetrated into every field of our lives, almost hard to find there was no sign of the single chip microcomputer which field. Missile navigation devices, control plane various kinds of instrument, computer network communication and data transmission, real-time control and data processing, industrial automation process widely used a variety of smart IC card, the security system of civil limousine tape recorders, cameras, fully automatic washing machine control, as well as program-controlled toys, electronic pets, etc., these are inseparable from the single chip microcomputer. Not to mention the robot in the field of automatic control, intelligent instruments, medical apparatus and instruments. Therefore, the single-chip learning, development and application will create a group of computer applications and intelligent control of scientists and engineers.
SCM mainly as a core component to use, according to the specific hardware structure, combined with the software according to the characteristics of the specific application object, to improve. In this article, the main content is to use single chip microcomputer interface technology to design the electronic clock, using digital tube to realize clock timing, make through the LE
