Is The Realtime Clock Locking Up My Program? If so how do I solve it?

Using Arduino Sensors
#1

Hey everyone, I am having a very strange issue with the realtime clock in Arduino that I cannot seem to solve. Basically, I have a program that logs data from a terrarium kit and saves each session to an SD card as a file named after the time the program started. 0

The problem with the program is that the code hangs on the statement before the setup section: “DateTime now = RTC.now().” The realtime clock appears to be functioning correctly with the example program which makes this issue even more strange. I am unsure if this is purely a software or hardware issue. From scouring the internet, I have found people with a similar problem to mine where the RTC will freeze up the i2c bus on the Arduino. However, I am unsure whether this is the issue plaguing me. If this is indeed the issue plaguing my program, unsure of how to work around it. I found an online solution here, however my program freezes upon launch so this would not work for me.

So far, I have tried:
-Replacing the coin-cell battery in the realtime clock (I am using 3 volt batteries)
-Replacing the datalogger shield with a new one
-Replacing the Arduino with a new one
-Checking to make sure that the jumpers were correctly soldered to the datalogger shield (Adafruit support checked mine through images and said they looked good)

I am running this program on IDE Version 1.6.9 with a program with the newer Adafruit datalogger shield on the Arduino Mega.

Any help would be greatly appreciated

Did you write the sketch or just edit it? Doesn’t look great.

Try attached which may fix the RTC issue, though I see some others.

That sketch uses RTClib.h. I don’t see where there it has # include <Wire.h>.
Try adding that before RTClib.h.
