Quick and easy solution for writing a linux device driver?

mr_segfault · 01-08-2004, 05:08 PM

Hi all,

I have an IO card which I use to interface to the outside world (form my PC), I use if for home automation.

The Card is a PCI card for which I don't have any device drivers for Linux..

I am porting my automation software to linux but need a device driver to access the card (please correct me if i'm wrong).

The current software I use is on Win95 and I just do direct ASM to read and write to the card (wrote my own inp and outp).

How can I write a simple device driver in linux? anyone have some example code? The device has a very simple interface, so it should't require much...

Thanks for any help you can provide..

Cheers

I also highly recommend O'Reilly's Book Linux Device Drivers. It is a damn complete reference of everything required to write device drivers under linux.
