This is my new 8 x 64 Dot Matrixs sign board and the first test. Still there is lot to improve. At the moment im working on character spacing algorithm.

And also you can see the characters isn't go with the display. Thats because my character gen is for 5X7 displays not for 8X8.

I hope to post here all of my improvements on this project.

Please post the schematics too. When you say code is messy, how did you work that as you have given in the photos and too in the video. Also share the final working files here.
