Trying to figure out what to do with the Value Line chips I decided to make a Persistence Of Vision text display, fitting in all the best bits of the ascii table.

The font in 5×7 pixels making the it 470 bytes including a smiley.

Ideally it wants a way of programming it without rewriting the whole program, perhaps a low speed soft serial on one of the Port2 pins, not sure yet.

The source file can be found here main.c

    Is there anything to sense when you change directions when waving it around? Or does it just repeat over and over?

      The program above will run through the message once only. In main you can put the for loop in a while loop and it’ll repeat the message, or you could trigger the for loop from a sensor.
