[WSS17] Mathematica connection to NI - Data Acquisition (DAQ) cards


[WSS17] Mathematica connection to NI - Data Acquisition (DAQ) cards

I have controlled hardware devices through serial ports, GPIB ports, USB ports using SerialRead/Write and NI - VISA from Mathematica. Here at WSS17, I wanted to control NI - DAQ cards using Mathematica. Through all these device communication protocols, large number of devices can be controlled which enables me to run my experiments efficiently using Mathematica.

DAQ cards are used for efficient measurements as they are compact and occupy less space than traditional devices. NI-DAQmx is an efficient driver to control NI-DAQ cards. In WSS17, I developed Mathematica-DAQmx Link ("DAQmxLink"), which links NI-DAQ cards with Mathematica through the communication between Mathematica NETLink and NI-DAQmx .

I can read the individual data too.

This is the basic connectivity between Mathematica and NI DAQmx.
