Error when include WidgetRTC.h

Issues and Errors
1

On my sketch I’m using the following library:

#include <SimpleTimer.h>
#include <Time.h>
#include <TimeLib.h>
#include <SunLight.h>
#include "RTClib.h"

with no problem, if I also include the:
#include <WidgetRTC.h>

I get the followings errors:

In file included from C:\Users\Igor\Documents\Arduino\myReef2_Mega\myReef2_Mega.ino:17:0:

C:\Users\Igor\Documents\Arduino\libraries\Blynk/WidgetRTC.h: In function 'time_t WidgetRTC_impl::requestTimeSync()':

C:\Users\Igor\Documents\Arduino\libraries\Blynk/WidgetRTC.h:36:5: error: 'Blynk' was not declared in this scope

     Blynk.syncVirtual(WidgetRTC::mPin); // Request RTC widget update from the server

Some ideas?

@naamah75 do you have the Blynk libraries in your sketch?

Have to tried with just one Time library and what is the difference between one and the other?

3

I’m using ESP8266_Lib.h and BlynkSimpleShieldEsp8266.h as Blynk libraries (that’s obiously I’ve included on my sketch).
Using only WidgetRTC.h and Time.h the problem doesn’t change.

Can you post the complete sketch? It’s a little hard to see what’s going wrong with limited information :slight_smile:

I’m guessing it is because you have too many time libraries and they are conflicting.

@Lichtsignaal, my sketch is over 2500 lines… I think it’s impossible to post here.
@Costas, okay, but I’ve tried with only WidgetRTC.h and Time.h and the problem persist.

Where are you getting Time.h from as there are several versions?

That is a big one indeed. Have you tried the simple examples? I always go from there and integrate them into my own sketches via copy/paste. That way I’m pretty sure it’ll work like I want it too.

That is the wrong library. As per RTC example you need #include <TimeLib.h>

Try all widget test sketches before integrating into your own sketches.

I’m talking about this Time.h library

You don’t want to be using that unless you are running a very old version of the IDE, see my last post for the correct library.

Ok, maybe this it’s the problem, but to verify I need to rewrite all my code using the Time.h … I need much time to do.
Anyway thanks for your suggest! :ok_hand:

The time libraries are all VERY similar so yu shouldn’t have to rewrite much, or any, code.
