AT24C02的多字節數據讀寫

這一點東西，弄個我一個小時，果然我還是太菜了

unsigned char MultiByte_write (unsigned char add , int dat )//首地址  數據 返還尾地址
{
    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;
}
