AT24C02的多字节数据读写

这一点东西，弄个我一个小时，果然我还是太菜了

unsigned char MultiByte_write (unsigned char add , int dat )//首地址  数据 返还尾地址
{
    while(dat!=0)
    {
        Write_AT24C02(add,dat);
        dat>>=8;
        Write_AT24C02(add,dat);
        add<<=1;
        Delay1ms();
    }
    return add;
}

int MultiByte_read (unsigned char add , unsigned char add1)//首地址 尾地址
{
    int temp;
    unsigned char i=0;
    while(add < add1)
    {
        temp=Read_AT24C02(add);
        add<<=1;
        i++;
        temp = Read_AT24C02(add) << 8*i | temp ;
    }
    return temp;
}
