Rotation / Display orientation

[MachmaHinne]

For solving my problem with the wrong orientation of the matrix module, I made a few changes. I´m not a coder and not familiar with contributions and pull requests, so I write it here:

In Settings.h I added: /*

• Define if and how the displays are rotated. The first display
• (0) is the one closest to the Arduino. rotation can be:
• 0: no rotation
• 1: 90 degrees clockwise
• 2: 180 degrees
• 3: 90 degrees counter clockwise
• If your matrix module is not right orientated try another setting */ int rotationValue = 3;

In marquee.ino I changed :

matrix.setRotation(i, 3); to matrix.setRotation(i, rotationValue);
