proprietary software and DAQ

[memez]

Hi, 

I work for an Italian company  that operates in the field of acoustics. 

We developed a software that we use to collect data from an accelerometer and a strength   
sensor, to extrapolate dynamic rigidity measures, visualize graphics in the time  domain and do FFTs. 

The interface between PC and the measurement machine is an obsolete compact flash   
DAQ and we are looking forward to substitute it with a more up-to-date USB DAQ. 

The only problem might be: is it possible to configure our software  to acquire raw data   
directly from the usb DAQ  without going through WinDAQ or similar softwares?

Hello Memez,

I still don't have a good picture of what you are looking for or what you are currently working with. From your post I see that there is a PC and a measurement machine.

Which one is connected to your current DAQ?

How are the PC and the measurement machine connected?

Additionally...

What operating system will be directly connected to the USB device?

What software are you currently using to communicate with the device and analyze data? Do these need to be replaced as well?

If you are running a recent version of Windows (XP to 8), you can use the DAQmx driver to access a NI USB device. The driver has a C and LabVIEW API so you can use it from your C or LabVIEW applications. This page has some resources you may find helpful.
