// Created 29 March 2006

// This example code is in the public domain.

#include <Wire.h>

#define ADDRESS 0x49

void setup()

{

  Wire.begin();        // join i2c bus (address optional for master)

  Serial.begin(9600);  // start serial for output

}

void loop()

{

  Wire.requestFrom(ADDRESS, 2);    // request 2 bytes from slave device #ADDRESS

  while(Wire.available())    // slave may send less than requested

  { 

    char c = Wire.read(); // receive a byte as character

    Serial.print(c);         // print the character

  }

  delay(500);
