一、DS1302时钟模块简介

二、绘制Proteus 仿真电路图

三、编写51单片机代码

#include "DS1302.h"// 位定义
sbit DS1302_DATA = P3^3;
sbit SCLK = P3^2;
sbit RST = P3^1;// 向DS1302写一个字节
void DS1302_Write_Byte(unsigned char addrOrData)
{unsigned char i;for (i = 0; i < 8; i++){DS1302_DATA = addrOrData&(0x01<<i);SCLK = 1;SCLK = 0;}
}// 向DS1302寄存器写数据
void DS1302_Write(unsigned char addr, unsigned char dat)
{RST = 0;SCLK = 0;RST = 1;DS1302_Write_Byte(addr); // 写入寄存器地址DS1302_Write_Byte(dat);  // 写入数据RST = 0;
}// 读取数据
unsigned char ds1302_read_byte()
{unsigned char dat = 0x00;unsigned char i;for (i = 0; i < 8; i++){if(DS1302_DATA){dat|=(0x01<<i);}SCLK = 1;SCLK = 0;}return dat;
}unsigned char ds1302_read(unsigned char addr)
{unsigned char dat;RST = 0;SCLK = 0;RST = 1;DS1302_Write_Byte(addr);dat = ds1302_read_byte();RST = 0;return dat;
}void DS1302_Init()
{DS1302_Write(0x8E, 0x00);DS1302_Write(0x84, 0x19);	// 写入时DS1302_Write(0x82, 0x06);	// 写入分DS1302_Write(0x80, 0x30);	// 写入秒DS1302_Write(0x8E, 0x80);
}
