8x8 Scrolling LED display (Simple example)

[wellyboot]

Hello,

I have built a simple 8x8 LED matrix that scrolls a message, in my example i am scrolling " D J W " followed by a smiley face.

I used standard yellow leds, which are ok, I would however recomend using higher brightness leds and adjusting the PORTB output resistors to suit.

I have attached a text file of code, I warn you now im no expert at writting code and not as experienced as some guys on here are, i have based it around 16F872 as i had 1 handy, and hope someone finds it useful!

Ill try and post a circuit diagram later
