Programming Devices in Software
National Instruments measurement devices are packaged with NI-DAQ
driver software, an extensive library of functions and VIs you can call from
your application software, such as LabVIEW or LabWindows/CVI, to
program all the features of your NI measurement devices. Driver software
has an application programming interface (API), which is a library of VIs,
functions, classes, attributes, and properties for creating applications for
your device.
NI-DAQ includes two NI-DAQ drivers, Traditional NI-DAQ (Legacy) and
NI-DAQmx. M Series devices use the NI-DAQmx driver. Each driver has
its own API, hardware configuration, and software configuration. Refer to
the DAQ Getting Started Guide for more information about the two drivers.
NI-DAQmx includes a collection of programming examples to help you get
started developing an application. You can modify example code and save
it in an application. You can use examples to develop a new application or
add example code to an existing application.
To locate LabVIEW and LabWindows/CVI examples, open the National
Instruments Example Finder.
• In LabVIEW, select Help»Find Examples.
• In LabWindows/CVI, select Help»NI Example Finder.
Measurement Studio, Visual Basic, and ANSI C examples are located in the
following directories:
• NI-DAQmx examples for Measurement Studio-supported languages
are in the following directories:
– MeasurementStudio\VCNET\Examples\NIDaq
– MeasurementStudio\DotNET\Examples\NIDaq
• NI-DAQmx examples for ANSI C are in the
