Hi Majd,

Your solution will depend on what type of DAQ device you are using. If it is possible, use the DAQmx driver and API to control the DAQ card. You can determine what DAQ device you have by opening Measurement & Automation Explorer and navigating to My System » Devices and Interfaces. Your card will then either appear under either NI-DAQmx Devices or Traditional NI-DAQ (Legacy) Devices. If you don’t see anything there, check the Windows Device Manager.

If you are using DAQmx, take a look at the following tutorial. It’s great for getting started with the API:

If you have any more questions, please post what DAQ device you are using and what driver. Have a great day!
