基于单片机的电子时钟设计

基于单片机的电子时钟设计论文摘要 本文介绍了基于单片机的电子时钟的设计方案和目标。电子时钟是一种计时工具，通过延时程序产生一定的时间中断，实现计时功能。本设计采用89C51单片机作为核心，能够显示时、分、秒，并具有时和分的校对功能。设计方案包括总体设计方案说明、系统方框图和系统流程图。设计目标是在数码管上显示相应的时间，并通过控制键实现时间调整和省电模式的转换。关键词包括89C51、电子时钟和LCD1602。本设计旨在通过将数字电路的知识应用于实际，提高综合分析和设计电路的能力。 Abstract: This paper presents a design plan and objective for an electronic clock based on a single-chip microcontroller. The electronic clock is a timing tool that uses a delay program to generate a certain time interrupt for timing purposes. This design uses the 89C51 microcontroller as the core and is capable of displaying hours, minutes, and seconds, as well as allowing for adjustments in hours and minutes. The design plan includes a general design description, system block diagram, and system flowchart. The objective of the design is to display the corresponding time on the digital tube and allow for time adjustment and power-saving mode switching through a control key. Keywords include 89C51, electronic clock, and LCD1602. This design aims to integrate the scattered knowledge of digital circuits learned into practical application in order to enhance the ability in comprehensive analysis, circuit design, programming, and circuit debugging.
