How can I use this to achieve what I want?
It would be helpful if you could provide some information on your system, make/model, what ports are available, etc. A matrix keypad (4x4) requires at least 8 directional signal paths, 4 output and 4 input unless you also use multiplexing which requires more hardware.
Is this for a desktop or laptop system? It's much easier to do on a desktop in which you can add an interface card.
As to the software you indicate, we can't say what it does without looking at it's listing which could vary with kernel version and distro. It is a "c" program which may need to be compiled depending on its format.
Supply the forum with the above info and we'll try to be more helpful.
