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.

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