The driver is connected to the proc file-system under Linux.

Load with : insmod xadio.o (Driver)

For each card, the following files are created:

· /proc/xadio/xadio0 /proc/xadio/xadio0 /proc/xadio/xadio0	/values /control /samples		Card 0
· /proc/xadio/xadio1 /proc/xadio/xadio1 /proc/xadio/xadio1	/values /control /samples		Card 1
· /proc/xadio/xadio2 /proc/xadio/xadio2 /proc/xadio/xadio2	/values /control /samples		Card 2
· /proc/xadio/xadio3 /proc/xadio/xadio3 /proc/xadio/xadio3	/values /control /samples		Card 3
Directory	File

values : is a text-file for reading the actual Measurement
control : is a text-file for reading and writing
samples : is a binary-file for reading

Output:

With help of the command:

cat /proc/xadio/xadio0/values

the actual card values will be shown.
