i2c coding problem

Hi all I am using ATmega128 controller and using i2c bus eeprom to increase its memory space . I have i2c header file in my codevision avr and i used them and change that accordingly but when i m reading my eeprom i m geting nothing i think that my code is either not able to generate the clock pulse or not able to write the data into eeprom i m not getting ,how to genrate the clk ?

#include

// I2C Bus functions port D #asm .equ __i2c_port=0x12 .equ __sda_bit=1 .equ __scl_bit=0

#endasm #include #include // Declare your global variables here /* read a byte from the EEPROM */

unsigned char eeprom_read(unsigned char EEPROM_BUS_ADDRESS , unsigned char address) { unsigned char data; i2c_start(); i2c_write(EEPROM_BUS_ADDRESS); i2c_write(address); i2c_start(); i2c_write(EEPROM_BUS_ADDRESS | 1); data=i2c_read(0); i2c_stop(); return data; }

/* write a byte to the EEPROM */ void eeprom_write(unsigned char EEPROM_BUS_ADDRESS,unsigned char address, unsigned char data) { i2c_start(); i2c_write(EEPROM_BUS_ADDRESS); i2c_write(address); i2c_write(data); i2c_stop(); /* 10ms delay to complete the write operation */ delay_ms(10); }

unsigned char eeprom *ptrom; void main(void) { unsigned char i;

// Declare your local variables here

// I2C Bus initialization i2c_init();

ptrom=0x0000;

/* write the byte 55h at address AAh */ eeprom_write(0x0182,0x00aa,0x43);

PORTB=0X00; delay_ms(500); PORTB=0XFF; delay_ms(500); /* read the byte from address AAh */ i=eeprom_read(0x0182,0x00aa);

while (1) {

}; }

need ur help thanx
