Curious to know why the size of font changes how text is displayed?
If you choose a large font - once it reaches the edge of the display the first characters 'scoll' off and the new characters come on the end.
With the small font that spreads across two lines - it basically fills both lines and then stops. Any reason why the small fonts can't be scrolled like the larger fonts?

RuralGeek, are you able to post your sketch code for me to take a look at?

Fairly sure it was the SAMPLES -> DMD2 -> ScrollingAlphabet

Will try it in the morning to confirm this.

Can confirm from the built -in sample, if you use this font: const uint8_t *FONT = Arial14;
The display simply keeps scrolling the text continuously.

With this font: const uint8_t *FONT = SystemFont5x7;
It fills the display and then stops...

Will investigate the code a bit more in depth over the weekend.

Why can´t I use a different font with DMD2 ? I modified a standar font but I had to use the same name ( Arial_Black ) because it doesn´t let me use a font with another name on the compilation. Sorry for my english.

Is there any instruction to replace "stepMarquee" of DMD library ? I´ve tried with "marqueeScrollX" but the scrolling is too slow using 4 P10 panels.
Thanks

Hi, How do I connect a 5x2 panel to arduino? with this dmd2 library, since the other one does not work for me at all.
