DS 1307 WITH ENERGIA

Hello,

I am keerthana.I am using energia version 0005a. I am working with real time clock DS1307, and i have added the library file .After adding library the library is found in examples but while running it i get an error. Can anyone help me in correcting this error?

#include <Wire.h>
#include "RTClib.h"

RTC_DS1307 rtc;

void setup () {

  Serial.begin(57600);

#ifdef AVR

  Wire.begin();

#else

  Wire.begin(); // Shield I2C pins connect to alt I2C bus on Arduino Due

#endif

  rtc.begin();

 

  if (! rtc.isrunning()) {

    Serial.println("RTC is NOT running!");

    // following line sets the RTC to the date & time this sketch was compiled

   // rtc.adjust(DateTime(F(__DATE__), F(__TIME__)));

    // This line sets the RTC with an explicit date & time, for example to set

    // January 21, 2014 at 3am you would call:

     rtc.adjust(DateTime(2014, 1, 21, 3, 0, 0));

  }

}

 

void loop () {

    DateTime now = rtc.now();

   

    Serial.print(now.year(), DEC);

    Serial.print('/');

    Serial.print(now.month(), DEC);

    Serial.print('/');

    Serial.print(now.day(), DEC);

    Serial.print(' ');

    Serial.print(now.hour(), DEC);

    Serial.print(':');

    Serial.print(now.minute(), DEC);

    Serial.print(':');

    Serial.print(now.second(), DEC);

    Serial.println();

   

   

    delay(3000);

}
