I will post a codeshare project shortly, but I wanted to preview more LedMatrix coolness before I finish cleaning the code for release.
This is 3 of the LedMatrix modules showing scrolling text using a custom 6x8 font I created to go with it. I created an Excel spreadsheet to help with font character creation that will be included with the project. The 6x8 font allows 4 characters at a time to be displayed on 3 modules. With 8 modules, you could get 10 characters.
So, snap up those modules while they are on sale.
