Hai everyone,

                  I have some doubt in the following program

* In both read and write mode why we are using  I2CSend(0x00); I2CSend(0x00);

* In read mode why we are using   I2CAck(); I2CNak();.In I2c Ack has been automatically generated by slave then why should we are giving Ack and Nak

    
   

 

////////////////EEPROM READ and WRITE\\\\\\\\
    
    I2CInit();
    
    I2CStart();
    
    I2CSend(0xA0);
    
    I2CSend(0x00);
    
    I2CSend(0x00);
    
    for(j=0;j<6;j++)
    {
    I2CSend(I2CData[j]);
    }
    
    I2CStop();
    
    __delay_ms(100);
    
    I2CStart();
    
    I2CSend(0xA0);
    
    I2CSend(0x00);
    
    I2CSend(0x00);
    
    I2CRestart();
    
    I2CSend(0xA1);
    
    for(j=0;j<6;j++)
    {

    rcdata[ j]= I2CRead();
    
    I2CAck();
    }
    
    if ( i – 1)

    I2CAck();

    else

    I2CNak();

    I2CStop();

    LCD_OUT(2,7,rcdata);

while(1);
  
}
