Hi, there is any simple way to scroll text in a 32x8 Led Matrix with MAX7219 controller? Any help will be appreciated.

Thanks and regards

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);

Formatting Help

Don't worry about formatting, just type in the text and we'll take care of making sense of it. We will auto-convert links, and if you put asterisks around words we will make them bold.

Tips:

Create headers by underlining text with ==== or ----

To *italicise* text put one asterisk each side of the word

To **bold** text put two asterisks each side of the word

Embed images by entering:
![](https://www.google.co.uk/images/srpr/logo4w.png)
That's the hard one: exclamation, square brackets and then the URL to the image in brackets.

* Create lists by starting lines with asterisks

1. Create numbered lists by starting lines with a number and a dot

> Quote text by starting lines with >

For syntax highlighting, surround the code block with three backticks:

```

Just like Github, a blank line must precede a code block.

If you upload more than 5 files we will display all attachments as thumbnails.
