Hi
I needed an 8x8 matrix to scroll text for a new project I'm working on.
I found it hard to find any C code to do this, so I wrote my own and posted it on my blog hoping others will find it useful.
I used this matrix;

When starting the program, you will need to specify the i2c bus, address of the matrix and the text to scroll.
Eg:
pi@raspberrypi ~ $sudo ./matrix 1 112 “this is the text to scroll”
