How to install ADS7846

I would install ADS7846, I read your website : AD7873 Input Touch Screen Digitizer Linux Driver [Analog Devices Wiki] .  I downoladed ADS7846.c and ads7846.h. But as I'm new in Linux and C. I didn't understand clearly what should I do?

I taped 2 commands :

root:~> modprobe evdevroot:~> modprobe ads7846

But no thing happend.

Would you help me?
