8x8 LED matrix, convert rainbowduino to MAX7219

Hi,

I'm a newbie, reading a lot and trying to learn when I can. :)

As a first project, I'd like to make something similar like this, with a 8x8 LED matrix Single color, but on a bigger scale. https://www.youtube.com/watch?v=AspZ8Np3_Bo It's basically a low resolution fire animation.

The guy who made this works with a RGB led grid and drives it with a rainbowduino. I would like to make a similar animation, but with single color led matrix, and would like to know if its possible to convert the code (that is provided by the maker of the project) to work with a MAX7219 driver.

Thank you very much for any advise and have a good day, Kurt
