PC104 card access ???

[Saqib51]

Hello !!

Can we access PC104 cards using NI-DAQ MAX or VISA ?? if not then how can we read analog input using labview of pc- 104 based cards ??

DAQmx is specifically for NI hardware only!

VISA is most likely not an option either. While VISA has some register API this is only for VXI and PXI hardware, usually from NI too. PC-104 being in principle still mostly an AT Bus interface is even further away from PXI than a generic PCI interface would be.

What you have to have is a driver from the hardware manufacturer of your PC-104 card in the form of a DLL (or shared library for non Windows systems) that is compatible with your used operating system. Then you have to develop a LabVIEW interface using the Call Library Node in LabVIEW to develop VIs for each of the shared library functions that you need to call in this driver.

Selling hardware boards without such shared library drivers for the most common OSes out there (Linux 32 and 64-bit, and Windows 32 and 64-bit) is something that one could do 30 years ago but nowadays this is simply not a viable option if such a hardware manufacturer wants to sell its hardware to anyone but advanced hardware integrators.

Developing a driver for such hardware is pretty involved and for any modern OS involves a kernel based driver component to do the actual hardware register access and high performance operations like interrupt and DMA programming and a user space component in the form of a shared library that provides a common API to the hardware driver.

thankx... i will try
