A simulation of a large scrolling LED display. Type in any text and it appears in large letters. Each letter is made from an 8X8 array of LED's.
Fonts are easily changed, added to or adjusted. The method illustrated how to use a state machine that is prorgammable. It takes
the text string and character by characterselects the right LED font for display. Can be made to scroll for ever if you put a While loop around it all.
Note, spaces are entered by the & character. Otherwise you don't need to do anything but run this and it will work. Much simpler than other approaches
but still can be improved. Gives you the basic idea of how to have a programmable state-machine. Note - uses upper case letters only.
I cant download this program could you share the Vi please
