There is an open source project called Comedi that might at least
provide the drivers for the data acquisition equipment. Have a look at
http://www.comedi.org/.


-----------------------

I used the comedi drivers to write code for the Diamond dmm32at card.  But, there were a couple of other 
cards that I wrote the drivers by hand, and the interface code was written in bash.  These were all PC/104 
cards.  One was called Pearl, and was just a set of 16 switches, either open or closed.  You couldn't even 
tell whether a switch was open or closed, so I had to keep state information.  You got the state from the 
/proc interface.

Anyway, comedi is easy, but depending on the board, it may be overkill.

I also write one for the Sensoray model 518.  It was a lot of sensors, current loops, thermocouples, things 
like that.  I wrote it by hand, also.  I'm not sure if comedi would have been too much or not.
