Dear all,
I am looking for the PCI digital I/O board supported on QNX 6.x.
(16 input/output or 32 input/output)
Does anyone know which board is available ?
Thanks in advance.

Actually, you don’t need any driver to access most of digital I/O boards
(i.e. Advantech or ICP or similar ones). To get input values, you usually
simply read from some I/O port(s), and to set output values, you simply
write
to some (usually the same) port(s). The only problem is to define the I/O
addres
for the PCI board which usually is assigned by BIOS during startup.
To do this you need access to the PCI configuration registers space.
You can do it by two ways - directly via special I/O port or usig BIOS int
1Ah.
See, for example, http://poli.cs.vsb.cz/misc/rbint/ix/index.html
I tried both the ways in QNX 4.25 - they work. I think it must work
in QNX6 as well.

I have been using the Acromag IP470 with success. It is in an Industrial
pack form factor so you would need a PCI → IP carrier. They also sell QNX
drivers. I have heard that they are planing a PCI version of the DIO board.
