24c02驱动代码。

void iic_star(void ) //iic start
{
            iic_scl = 1;             // scl保持
            iic_sda = 1;
            iic_delay();

            iic_sda = 0;                                           // sda下降跳变
            iic_delay();
            iic_scl = 0;

}

void iic_end(void)    // iic end
{
            iic_sda = 0;
            iic_delay();
            iic_scl = 1;
            iic_delay();
            iic_sda = 1;
            iic_delay();
}

void iic_write_byte(unsigned char dat)    //iic write byte
{
            unsigned char i,temp;
            temp = dat;

            for(i=0;i<8;i++)
                     {
                              temp = temp << 1;
                              iic_scl = 0;
                              iic_delay();
                              iic_sda = CY;
                              iic_delay();
