I have been trying to have a feel of the subject.
  My objectives are:
  1) To write to an EEPROM 
  2) Read the same from the EEPROM
  3) Put the data on the port for display to verify.
   
  I am using Proteus for the simulation.
  Below is my code which is not working, I cant get the led blink properly. 
  I shall appreciate the corrections Pls.
   
  ==================The Code=====================
  #include <16f84.h>
//EEPROM = 24LC00
// Configure PIC to use: XT clock, no code protection 
// Disable Power Up Timer, no Watchdog Timer,
  #fuses XT, NOPROTECT, NOPUT, NOWDT
  // tell compiler clock is 4MHz.  This is required for DELAY_MS()
// and for serial I/O, all of which use software delay loops.
#use delay (clock=4000000)
  
// declare that we'll manually establish the data direction of
// each I/O pin on ports A&B.
#use fast_io ( a )
#use fast_io ( b )
   
  #use I2C(master, SCL=PIN_A0, SDA=PIN_A1)
   
  #byte   PORT_B  =   6           /* set variable that maps to memory */
   
  void main(void)
{
   int data;
   
   set_tris_a (0b00000000);              /* set up I/O's */   
   set_tris_b (0b00000000);              /* set up I/O's */
   
   while(true)
   {
      PORT_B=0;
      delay_ms(500);
      data=0xff;
      i2c_start();
      delay_ms(10); /* Wait for some time to let the Memory*/
      i2c_write(10);/* The address to write to*/
      delay_ms(10);
      i2c_write(data);
      delay_ms(10);
      i2c_stop();
      delay_ms(10);
      i2c_start();
      delay_ms(10);
      i2c_write(11);
      delay_ms(10);
      data=i2c_read();
      i2c_stop();
      delay_ms(10);
      PORT_B=data;
      delay_ms(500);      
   }      
}

  ==================End Code=========================
