    I learned many things from this site visit this site & look under 5X7 project.
    http://www.talkingelectronics.com/te_interactive_index.html

    I used a similar technic that I used in my design if you got the correct picture you can scroll any pattern that you like.For that you need to write more coding.The code they provided is only for one way scrolling & its very long in my method I used indirect addressing that will be more difficult to a beginner.

    All the techniques to drive large displays using special code are great. I have been in this game long enough to learn that years of developing clever schemes ends up almost in vain. Because one day soon, enters any one of the higher-pin count, double to quadruple code size, and peripherals galore cheaper than the older 18-pin devices to come along and disrupt all that "design around limitations" ingenuity.
