Q: 

How to make a scroller on a micro-processor/-controller?

I would like to write a text scroller on a micro-processor with 4 5x7 displays in ANSI-C.

Does anyone know of example source code or anything that can help me get started?

Update

This is the user manual for the micro-processor board I have. On PDF page 17 is a picture of the board with the displays.

The code is written in an IDE called "zds2_Z8Encore493.exe" and then flashed to the micro-controller over serial port.

I would like the text to cascade from one to the next to the next column-by-column, so it is smooth.
