单片机时钟程序

单片机时钟程序 实验目的:通过电子时钟的综合实验掌握单片机编程的基本思想，学会对一些周边芯片的综合利用。通过实验，真正理解所学知识。 实验要求:数码管型时钟，可以显示时间、日期、星期、闰年，并有整点报时及闹铃，农历功能。 实验器材:主要用到的芯片有:PCF8563时钟芯片，ZLG7290键盘检测及LED显示模块，蜂鸣器及51单片机。系统概述:先对时钟芯片初始化，然后取出数据，进行处理，农历转换，并判断是否整点及到达定时时间，根据判断到的按键，进行相应的处理及显示。硬件介绍:1、ZLG7290ZLG7290是一I2C接口键盘及LED驱动管理器件，提供数据译码和循环、移位、段寻址等控制。它可采样64个按键或传感器，单片即可完成LED显示、键盘接口的全部功能。ZLG7290的从地址为70H，器件内部通过I2C总线访问的寄存器地址范围为00H~17H，任一寄存器都可按字节直接读写，并支持自动增址功能和地址翻转功能。使用 ZLG7290 驱动数码管显示有两种，第一种方法是向命令缓冲区(07H-08H)写入复合指令，向 07H 写入命令并选通相应的数码管，向 08H 写入所要显示的数据，这种方法每次只能写入一个字节的数据，多字节数据的输出可在程序中用循环写入的方法实现;第二种方法是向显示缓存寄存器(10H~17H)写入所要显示的数据的段码，段码的编码规则为从高位到低位为 abcdefgdp ，这种方法每次可写入 1~8 个字节数据。ZLG7290 读普通键的入口地址和读功能键的入口地址不同，读普通按键的地址为 01H，读功能键的地址为 03H。读普通键返回按键的编号，读功能键返回的不是按键编号，需要程序对返回值进行翻译，转换成功能键的编号。2:PCF8563时钟芯片PCF8563是PHILIPS公司生产的低功耗CMOS实时时钟/日历芯片，芯片最大总线速度为400kbits/s，每次读写数据后，其内嵌的字地址寄存器器会自动产生增量。PCF8563可广泛应用于移动电话、便携仪器、传真机、电池电源等产品中。 PCF8563有16个8位寄存器，其中包括:可自动增量的地址寄存器、内置32.768kHz的振荡器(带有一个内部集成电容)、分频器(用于给实时时钟RTC提供源时钟)、可编程时钟输出、定时器、报警器、掉电检测器和400kHz的I2C总线接口。 所有16个寄存器设计成可寻址的8位并行寄存器，但不是所有位都有用。当一个RTC寄存器被读时，所有计数器的内容将被锁存，因此，在传送条件下，可以禁止对时钟/日历芯片的错读。 3:I2C介绍 1、只要求两条总线线路:一条串行数据线SDA，一条串行时钟线SCL; 2、每个连接到总线的器件都可以通过唯一的地址和一直存在的简单的主机/从机关系软件设定地址，主机可以作为主机发送器或主机接收器; 3、它是一个真正的多主机总线，如果两个或更多主机同时初始化，数据传输可以通过冲突检测和仲裁防止数据被破坏; 4、串行的8 位双向数据传输位速率在模式下可达100kbit/s，快速模式下可达400kbit/s，高速模式下可达3.4Mbit/s; 5、连接到相同总线的IC 数量只受到总线的最大电容400pF 限制。 实验原理:选用的时钟芯片及显示模块均采用了I2C总线标准，使整个系统接线更简单，并且数据传输更简单。 程序主要由以下几部分组成: I2C读写: 写数据 ISendStr(uchar sla,uchar suba,uchar *s,uchar no) ; 读数据IRcvStr(uchar sla,uchar suba,uchar *s,uchar no); ZLG7290数码管显示及键盘取键值: 发送数据ZLG7290_SendData(unsigned char SubAdd,unsigned char Data); 显示数据ZLG7290_SendBuf(unsigned char * disp_buf,unsigned char num); 发送命令ZLG7290_SendCmd(unsigned char Data1,unsigned char Data2); 取键值 ZLG7290_GetKey(); 农历转换部分，闹铃显示，整点报时等。 程序开始，首先初始化PCF8563时钟芯片，然后进入while循环，进行显示及键盘判断。程 序设置了几个全局变量，专门用于存储按键次数，达到一键多用的效果。下面的程序根据按键的次数，选择处理不同的数据或进行不同的操作。 本程序共用了5个按键，其中1键专门用于切换显示，2键用于修改时间及星期，3 键用于调整日期，4键用于修改闹铃。5键专门用于调整。 c程序: #include"reg52.h" #include"VIIC_C51.H" #include"zlg7290.h" #include "intrins.h" #include "18b20.h" //温度:ReadTemperature() #define PCF8563 0xA2 //定义器件地址 #define WRADDR 0x00 //定义写单元的首地址 #define RDADDR 0x02 //定义读单元的首地址 #define uchar unsigned char #define uint unsigned int unsigned char TempH,TempL;
