I am trying to install ADT7420 digital temperature sensor to Arduino Nano.
I have written a sketch for Arduino UNO, it works on Arduino UNO very well.
But same sketch couldn't work on Arduino NANO smiley-confuse

Could you kindly tell me what is wrong?
Please help me smiley-red

#include <I2C.h>
#define ADT 0x48

int i,ans;
long temp;      
double celsius;  

void setup()
  delay(10);             ,0x0B,1);        
  byte st=I2c.receive();      
  Serial.println(st, HEX);    

void loop()
  int i;
  byte xH,xL;

  xH = I2c.receive();        
  xL = I2c.receive();        
  Serial.print(": ");*/
  celsius = double(long(word(xH,xL)) * 100/128)/100.00;  

I use SCL as A5, SDA as A4.
