Text Scroll MAX7219 Matrix 32x8

As @Wilberforce says, take a look at the Multiple chained MAX7219 heading in the link above.

Then, it's just a matter of something like:

require("Font6x8").add(Graphics);
var text = "Hello world with lots and lots of text";
var x = 0;
function scroll() {x--;
  if (x<-g.stringWidth(text)) x=g.getWidth();
  g.clear();
  g.drawString(text, x, 0);
  g.flip();
}
setInterval(scroll, 20);
