RGB Matrix Library

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"

4


5
//-------Librarys LED Matrix-------------

6
#include <gamma.h>

7
#include <RGBmatrixPanel.h>

8


9
#include <Adafruit_GFX.h>

10
#include <Adafruit_SPITFT.h>

11
#include <Adafruit_SPITFT_Macros.h>

12
#include <gfxfont.h>

13


14


15
//------Defines for LED Matrix----------

16
#define CLK  8

17
#define OE   9

18
#define LAT 10

19
#define A   A0

20
#define B   A1

21
#define C   A2

22
#define D   A3

23


24
//--------Colour Variables-------------

25
int red, green, blue;

26


27
//--------All Pins for LED Matrix------

28
RGBmatrixPanel matrix(A, B, C, D, CLK, LAT, OE, false);

//---------Realtime Clock--------------

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 :):)
