PCI Data Acquisition Card

Is there any PCI Data Acquisition card with analog inputs and outputs
available for QNX 6.3?

Best,

Such cards are simple in nature and have a simple register set to match. Using the provided library is just adding more bugs to your project.

Recommendation: Buy a card, first make sure it *does* have docs on programming at the register level, and hit the metal.

Shashank,
I have used bus mastering PCI cards from Measurement Computing
(DAS4020, DAS6070, and DAS6025). Our applications only use the A/D
inputs of these cards, but they do have D/A outputs as well. There are
no QNX drivers for these cards that I know of. So, to use them, you will
need to get the register level programming guides from Measurement
Computing, and also the register level programming guide for the PLX9080
bus master chip from PLX.
