Maxime,
I have been using the DMM-32 for about 2 years (in user and real-time space)
and will send you some stuff this afternoon and explain it.

Subject: [rtl] dmm-32 io board problems
Hi everyone,
I'm trying to write code that will get values from my diamond systems io
board from rtlinux. Right now, all I really want is to initialise the
board
so that I can go and read a couple of voltages on 1 of its pins.
We are working with a jumptec PC-104 and the io board is a dmm-32-at
from
diamond systems. Our pc runs on Red Hat 7.0 with the 2.2.18-rtl patched
kernel and the rtlinux 3.0 libraries.
We looked around for information about this and found some info on using
vremap for this type of operations ( i.e accessing the io card from a rt
thread ... though we can't seem to find the vremap function anywhere).
We
also tried accessing it with insb and outb to no success. This is all
new for
us: we are starting to get comfortable with linux itself but linux,
rtlinux
and kernel programming are all new to us.
Here's my question: Does anyone have any experience working with the
board (
or similar boards ) and rtlinux. Could anyone point me out to some code
or
ressources that would help us run the thing and better understand how it
works. Could anyone that has worked with all rtlinux and the io board
give us
a couple of pointers on how to work with such material and so on?
Thank you for your time,
