hi

I am trying to interface TC74 with PIC. it is not working. What is wrong with the code?

LCD.JPG

Code: 
#include <18F452.h>   
#use delay (clock=4M) 
#include <flex_for_test_lcd.c>  //LCD driver
#fuses HS,NOLVP,NOWDT 
#fuses XT                     //for crystal
#use I2C(scl=PIN_C3, sda=PIN_C4) 



void main(){

int16 temp;

//LCD

output_low(PIN_E2);
lcd_init();
lcd_putc("Temperature:");
    

//I2C

i2c_start();    // Start condition
i2c_write(0x9A); //device Address 0x9A
i2c_Write(0x00);  

i2c_start(); 
i2c_Write(0x9B);  
temp = i2c_Read(0);
i2c_stop();     // Stop condition

printf(lcd_putc, "%lu" temp);

}
