Error compiling with RTClib for Arduino Uno

Projects Programming
1

Hi,

I'm setting up a project with the RTC library and just wanted to test some things out on my Arduino Uno. I have just some very simple test code below, but when I try to compile it gives me "exit status 1 Error compiling for board Arduino Uno". My rtclib folder is saved into Documents>Arduino>libraries and I've confirmed that my board and port are both correct, so I'm not sure what I'm missing here.

Below is my full code:

#include <RTClib.h>
#include <Wire.h>
RTC_DS1307 rtc;

void setup() {
  // put your setup code here, to run once:
  Serial.begin(9600);
  if(! rtc.begin()){
    Serial.println("Couldnt find RTC");
    while(1);
  }
  if(! rtc.isrunning()){
    Serial.println("RTC is NOT running!");
    rtc.adjust(DateTime(F(__DATE__), F(__TIME__)));
  }
}

void loop() {
  // put your main code here, to run repeatedly:
  DateTime now = rtc.now();
  Serial.print(now.year(), DEC);
  Serial.print('/');
  Serial.print(now.hour(), DEC);
  Serial.print('/');
  Serial.print(now.minute(), DEC);
}

And the error I'm getting is:

Any help would be much aprreciated!

You are missing the above library. The error message is perfectly clear:
fatal error: Adafruit_I2CDevice.h: No such file or directory

Oh I thought that was something wrong with my installation of RTClib, thank you for pointing that out the library is installed and working now!
