单片机课程设计——日历时钟与键盘显示程序设计姓名：管曌学号：3081109003班级：J通信0801指导老师：熊书明日历时钟与键盘显示程序设计一、设计目的（1）能在LED显示器上实现正常的时分秒计时（2）能通过键盘输入当前时间，并从该时间开始计时（3）有校时、校分功能（4）有报时功能，通过指示灯表示（5）有闹时功能，闹时时间可以设定，通过指示灯表示二、设计内容该课程设计是利用MCS-51单片机内部的定时／计数器、中断系统、以及行列键盘和LED显示器等部件，设计一个单片机电子时钟。

设计的电子时钟通过数码管显示，并能通过按键实现设置时间和暂停、启动控制等。

三、MCS-51单片机系统简介单片机应用系统由硬件系统和软件系统两部分组成。

硬件系统是指单片机以及扩展的存储器、I\O接口、外围扩展的功能芯片以及接口电路。

软件系统包括监控程序和各种应用程序。

在单片机应用系统中，单片机是整个系统的核心，对整个系统的信息输入、处理、信息输出进行控制。

与单片机配套的有相应的复位电路、时钟电路以及扩展的存储器和I\O接口，使单片机应用系统能够运行。

在一个单片机应用系统中，往往都会输入信息和显示信息，这就涉及键盘和显示器。

在单片机应用系统中，一般都根据系统的要求配置相应的键盘和显示器。

配置键盘和显示器一般都没有统一的规定，有的系统功能复杂，需输入的信息和显示的信息量大，配置的键盘和显示器功能相对强大，而有些系统输入/输出的信息少，这时可能用几个按键和几个LED指示灯就可以进行处理了。

在单片机应用系统在中配置的键盘可以是独立键盘，也可能是矩阵键盘。

显示器可以是LED指示灯，也可以是LED数码管，也可以是LCD显示器，还可以使用CRT显示器。

单片机应用系统中键盘一般用的比较多的是矩阵键盘，显示器用的比较多的是LED数码管还LCD显示器。

四、设计方案通过键盘输入，设置当前时间存入S-3530A，然后从S-3530A读取实时时间并显示在七段码LED显示上，键盘和LED显示通过键盘专用芯片HD7279A进行控制，7279A也是I2C总线接口的芯片，系统中采用并行口线模拟I2C实现C8051F020和HD7279A的通信，用硬件实现S-3530A和HD7279A的连接。

用定时／计数器T0，工作于定时，采用方式1，对系统时钟进行定时计数，初值设为23时59分50秒。

定时时间为50ms。

用片内RAM的7BH单元对50ms 计数，计20次产生秒计数器78H单元加1，秒计数器加到60则分计数器79H单元加1，分计数器加到60则时计数器7AH单元加1，时计数器加到24则时计数器清0。

然后把秒、分、时计数器分成十位和个位放到8个数码管的显示缓冲区，通过数码管显示出来。

显示格式为小时十位、小时个位---分十位、分个位---秒十位、秒个位。

在处理过程中加上了按键判断程序，能对按键处理，1是时加一,2是时减一，3是分加一，4是分减一，5是秒清零，D是闹钟时间的设定，E 是进行校时，F是暂停键。

五、系统软件设计流程：1.主程序流程如图所示:2.时间设定程序流程如图所示：3.闹铃设定流程图如图所示：六、程序#include "c8051f020.h"#include <intrins.h>#include "test7279.h"unsigned char Count1ms,set,set1,set2;// int count;static int time[3]={23,59,50};//current timestatic char disptime[6]={'2','3','5','9','5','0'};//显示时间int dertime[3]={00,00,01};int nowtime[3]={00,01,00};//闹钟时间void Delay1us(unsigned char us){while (us){_nop_();
