One of my client is running RT Linux in his machine. He inserted a
PCL-812pg
daq card there. Now, he needs to read data from that daq card for a real
time human body pulse rate measurement. I googled for it, but haven`t find
anything good enough. Can any one help me? How can we do that?
He is lucky. PCL-812pg is an ISA slot card and not PCI. Accessing the
functions of this card through the inb/outb family of functions in C is
quite simple. Write your own driver for this simple application. You have
pretty good documentation of the card's internal register map. It's simpler
to write it yourself.
Also your application seems to need only a counter/timer, why a multi
function card like the 812 was selected?! My opinion is that you should just
write a few lines of code to get access to the counter/timer in the 812
card.
You call also have a look at

It's a brilliant project and there is support for the PCL812PG.
All the best.
