-    id:	Id for the matrix. Currently always 0.
-    page: 	A page has a height of 14 pixel. For a matrix with HEIGHT == 14 this will be always 0
-    width: 	The width of the flip disc matrix. Always equal to WIDTH
-    row1: 	first data line (7 pixel per byte)
-    row2: 	first data line (7 pixel per byte)
