I have made a working model of Nigel's 8x8 matrix using my own scrolling message. Can I add more 8x8 matrix modules using the code I have" which is mostly Nigel's" and if so what do I need, and how do I go about it. As my coding experience is very limited any help I get would be appreciated. This is just a hobby for me in my later retirement years, that I enjoy very much. Thank you.
