[iPAQ] Help : accessing the extension port (FAST IO mode) of the ipaq

Hello,

I am working on a robotic project (http://team-id.epfl.ch) and we want
to use an IPaq (precisely IPaq 3660) running Familiar (and OPIE) as the
main controller of our robot.

I am the main programmer of that part, and I want to use a linux process
whose task would be to communicate with the sensors (make these info
available for the other IA processes through a shared memory segment,
which is well implemented in familiar) and send commands to the motors
and servo-motors).

According to that documentation
(http://handhelds.org/Compaq/iPAQH3600/iPAQ_H3600.html), as we have many
sensors and motors, we want to use the the Fast I/O mode of the
extension port, because a 32 bits wide data bus is necessary, and a 10
bits wide adress bus connected to our extern self-made address decoder
(which is being developped by myself in the team too) would be widely
enough for the number of sensors.

Now, to go on in that way, I need to know if there are system libs that
allow us to directly access this main extension port (I tried to find
them in the libs, but didn't manage it) ? If they exist, which are they
? If not, what should we do to access this extension port ?

I thank you a lot by advance, it would be a huge hint for us to tell us
about these libraries. If you could give me a precise contact about a
person having some experience about that topic would be greatly
appreciated too.

Best greetings
