2.Usage

As a minimum you will need to do the following function calls to display your message:-

Init(*Matrix, Width, Height, OriginX, OriginY);
SetFont(*FontData);
SetText(*Txt, TxtSize);
UpdateText();

And optionally, if you don't want to use the special character codes in your text array, you could call the following:-

SetBackgroundMode(Options, Dimming);
SetScrollDirection(Options);
SetTextDirection(Options);
SetTextColrOptions(Options, ColA1, ColA2, ColA3, ColB1, ColB2, ColB3);
SetFrameRate(Rate);
SetOptionsChangeMode(Options);

You should check the return code from the UpdateText() call as a value of -1 indicates that the end of the text array has been reached and either needs to be reset or set to a new text array with a call to SetText(*Txt, TxtSize).
