LED dot matrix scrolling message – 14×5 – source code

I have built various scrolling message badges for instance using the 16F57- 10×5 and 12×5. However, since these chips only have a small FLASH, there is not much flexibility. I don’t really recommend these controllers for a scrolling message. Recently I have started a new project, using small 1.9mm ready made modules, and a 16F884. It has 4K FLASH which is sufficient (about 1/3 are used), and 256 bytes RAM. ...
