Hi all

I wanted to create a word clock with a RGB LED Matrix. I bought the 
32x32 LED RGB Matrix off Adafruit (Product ID: 1484) and it looks 
awesome.
I 3D printed a front plate with the letters cut out.
my next idea was to combine it with a DCF77 module. but that wasnt 
reliable enough to use in the final version.
So i settled for a RTC. (Chip DS3231) which communicates with Arduino 
over I2C.
It doesnt seem to be working. I assume that the two librarys dont work 
together because they define a same thing in 2 different ways.
This is the whole code (im very sorry, some words are in swiss german, 
those are only variables to describe the time tho and could be chosen 
freely):
1
//-------Librarys Realtime Clock---------
2
//#include <Wire.h>
3
//#include "DS3231.h"

//-------Librarys LED Matrix-------------

It would be awesome if i could get a tipp about whats the problem.
Im quite stuck at the moment.

Every help is deeply apprechiated!
Greetings from switzerland and thanks in advance!

Cheers Fabian :):)

Sorry ich habe gerade gemerkt dass ich den Code als Datei angehängt 
haben sollte.
Tut mir leid, kann ich dies noch anpassen?
