If you place several LED matrices together.... say 4 at the top 4 in the middle and 4 at the bottom.. you will have 32 led's across and 24 down....
If you remember, I use it like a graphical LCD screen, as it is no different!!! If you organise it so you write the whole screen at once ( blitting ) and write all your functions to draw to a back buffer, it will look exactly the same....
Any... I use several graphical screens.... Once you write all your low level routines, you can port them to almost "Any" screen type including LED matrices..
