并能准确计算闰年闰月的显示。
设计要求：通过与单片机连接数码管动态显示年、月、日、时、分、秒、星期等功能，并能准确计算闰年闰月的显示，三个个按钮连接P3.0、P3.1、P3.2可以精确调整每一个时间数值，通过对所设计的万年历时钟电路进行实验测试，达到了动态显示时间，随时调整时间等技术所连线路和单片机接口仿真图如图3所示：图3 仿真按键4）温度采集部分：DS18B20温度传感器，测温范围－55℃～+125℃，固有测温分辨率0.5℃。
独特的单线接口方式，DS18B20在与微处理器连接时仅需要一条口线即可实现微处理器与DS18B20的双向通讯。
DS18B20的采集数据通过DQ传入单片机，单片机读取数据后将数据输出！如图所示：程序如下：ReadOneChar(void){unsigned char i=0;// 定义i用于循环unsigned char dat = 0;// 读取的8位数据for (i=8;i>0;i--)//8次循环{DQ = 0;// 拉低DQ总线开始读时序dat>>=1;// dat左移一位DQ = 1; //释放DQ总线if(DQ)// 如果DQ=1，执dat|=0x80；（0x80即第7位为1，如果DQ为1，即读取的数据为1，将dat的第7为置1，然后dat>>=1，循环8次结束，dat 即为读取的数据）//DQ=0，就跳过dat|=0x80;Tdelay(4);// 延时以完成此次读时序，之后再读下一数据}return(dat); 返回读取的dat}//写一个字节WriteOneChar(unsigned char dat){unsigned char i=0;//for (i=8; i>0; i--)//{DQ = 0;//DQ = dat&0x01;//Tdelay(5);//延时以完成此次读时序，之后再读下一数据DQ = 1;//dat>>=1;//}}//读取温度ReadTemperature(void){unsigned char a=0;unsigned char b=0;unsigned int t=0;float tt=0;//Init_DS18B20();WriteOneChar(0xCC);// 写指令，跳过ROM，WriteOneChar(0x44);// 启动温度转换Init_DS18B20();WriteOneChar(0xCC);// 写指令，跳过ROM，WriteOneChar(0xBE);// 写指令，读暂存存储器a=ReadOneChar();//读低8位b=ReadOneChar();//读高8位t=b;//t<<=8;//t=t|a;//tt=t*0.0625;//t= tt*10+0.5;//return(t); //获得0.01°C 的精度并返回}LED数码管的选择LED数码管分为共阴和共阳两种，以利用STC89C51的P0口作为LED显示的数据部分，以P2口的七个口作为显示部分的位选，通过三八译码器和4-16译码器扩展为17位的位选分别接在一个四位数码管和13个数码管的位选部分。

在数字显示方面，目前还可以直接采用CMOS-LED 光电组合器件，构成模块式石英晶体数字钟。
为了帮助同学们了解数字钟的组成，运用已学过的数字电路基本知识，掌握设计简单数字系统的方法，本课题介绍数字钟的设计制作方法。
1.1数字钟的组成和工作原理一个简单的数字钟，主要由六部分组成。
整机电路方框图如图1-1所示。
图1-1数字钟整机方框图（宋体，5号）1.1.1石英晶体振荡器模块振荡器主要用来产生时间标准信号。
因为数字钟的精度，主要取决于时间标准信号的频率及其稳定度，所以要产生稳定的时标信号，一般是采用石英晶体多谐振荡器，从数字钟的精度考虑，晶振频率愈高，钏表的计时准确度就愈高。
但这会使振荡器的耗电量增大，分频器的级数也要增多。
所以在确定频率时应考虑两方面的因素，然后再选定石英晶体的型号。
图1-2晶体振荡器之一100kΩ1.1.2分频器模块因为振荡器产生的时标信号频率很高，要使它变成能用来计时的“秒”信号，需要一定级数的分频电路。

培养我们综合运用电子课程中的理论知识解决实际性问题的能力。
让我们对电子电路、电子元器件、印制电路板等方面的知识进一步加深认识，同时在软件编程、排错调试、焊接技术、相关仪器设备的使用技能等方面得到较全面的锻炼和提高，为今后能够独立完成某些单片机应用系统的开发和设计打下一个坚实的基础。
课程设计的基本任务利用89C51单片机最小系统，综合应用单片机定时器、中断、数码显示、键盘输入等知识，设计一款单片机和简单外设控制的电子时钟。
主要功能要求最基本要求1)使用MCS-51单片机设计一个时钟。
要求具有6位LED显示、3个按键输入。
2)完成硬件实物制作或使用Pruteus仿真（注意位驱动应能提供足够的电流）。
3)6位LED数码管从左到右分别显示时、分、秒(各占用2位)，采用24小时标准计时制。
开始计时时为000000，到235959后又变成000000。
4)使用3个键分别作为小时、分、秒的调校键。
每按一次键，对应的显示值便加1。
分、秒加到59后再按键即变为00；小时加到23后再按键即变为00。
在调校时均不向上一单位进位 (例如分加到59后变为00，但小时不发生改变)。
5) 软件设计必须使用MCS-51片内定时器，采用定时中断结构，不得使用软件延时法，也不得使用其他时钟芯片。
6）设计八段数码管显示电路并编写驱动程序，输入并调试拆字程序和数码显示程序。

电子时钟原理电子时钟是现代人日常生活中常见的一种计时工具。
它的出现改变了人们对时间的感知和使用方式，成为人们生活中不可或缺的一部分。
本文将介绍电子时钟的基本原理、构造、工作方式和应用领域。
一、基本原理电子时钟的基本原理是利用电子元件的精确计时能力来显示时间。
它通过内部的电路系统，根据精确的时间信号来测量和显示时间，从而实现时间的准确记载和展示。
二、构造电子时钟主要包括以下几个组成部分：振荡器、计数器、显示器和电源。
1. 振荡器振荡器是电子时钟的核心部件，其作用是产生一个稳定的电信号用于计时。
目前常用的振荡器有晶体振荡器和石英振荡器，它们都能提供非常准确的频率信号。
2. 计数器计数器是用于计量时间的部件，它通过接收振荡器产生的信号来计算时间。
计数器可以是二进制计数器，每次计数到满时会增加一个单位的时间，同时显示器也会相应地改变。
3. 显示器显示器是将时间信号以可视化方式展示出来的部件。
目前常见的电子时钟显示器有LED显示器、LCD显示器和闹钟表盘等。
它们能够清晰地显示时间，并且具有较低的功耗。
4. 电源电子时钟需要一个稳定的电源来供电。
常见的电源有电池和交流电源两种形式。
电池供电的电子时钟通常体积较小、便携性较高，而交流电源供电的电子时钟通常功耗较高但更加稳定。
三、工作方式电子时钟的工作方式可以分为以下几个步骤：1. 振荡器产生稳定信号。
2. 计数器接收振荡器信号并进行计时。
3. 计数器将计时结果转化为可以显示的形式。
4. 显示器将计时结果以可视化方式显示出来。
四、应用领域电子时钟广泛应用于各个领域，包括家庭、办公室、学校、医院、车站等场所。
它不仅可以用于显示时间，还可以设置闹钟功能、定时开关等实用功能，方便人们的生活和工作。
总结：电子时钟是一种基于电子元件的计时工具，它利用振荡器产生的稳定信号来计量时间，并通过显示器将时间以可视化方式呈现给用户。
电子时钟在生活中起着重要作用，不仅能够帮助人们准确掌握时间，还提供了实用功能，方便人们的生活和工作。
摘要随着科学技术的不断发展，电子时钟已经成为一种普遍的工艺了。
日常生活中到处可见。
电子时钟的设计有很多种，普遍的电子时钟是基于单片机用汇编语言做成的扩展。
ARM功能也一样且更精确。
本文是详细介绍基于ARM上做成的电子时钟。
这个电子时钟的硬件是用LPC2103板， 8个按键和8个数码管组成的键盘显示板，还有LED灯当成闹铃使用。
此时钟还可以当成秒表使用。
这是一个基于ARM实现多功能的电子时钟。

然而随着时间的推移，尤其是在现在科技的发达，生活水平高，什么都讲究效率的年代。
人们不仅对时钟的精度要求高，而且对时钟的功能的要求也越来越多。
时钟已不仅仅是一种用来显示时间的工具，而是在很多实际应用中它还需要能够实更多的其他功能。
比如日历显示功能，秒表功能，闹钟功能，温度或湿度的测量电压测量等。
时钟数字化给人们的生活带来了极大的方便，而且也大大地扩展了钟表原先的保湿功能。
诸如定时自动报警，按时自动闹铃，定时广播，各种定时电气的自动启用等。
这些功能都是一钟表数字化为基础的。
可以说设计多功能数字时钟的意义已不不只在于数字时钟本身，更大的意义在于多功能数字时钟在许多实时控制系统中的应用。
在很多实际应用中，只要对数字时钟的程序和硬件电路加以一定的修改，便可以得到实施控制的实用系统，从而应用到实际工作与生产中去。
因此，研究数字时钟及扩大其应用，有着非常现实的意义。
