• If you are using other application software, refer to Common Sensors
in the NI-DAQmx Help or the LabVIEW Help in version 8.0 or later.
Programming Devices in Software
National Instruments measurement devices are packaged with NI-DAQmx
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. NI-DAQmx
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. DAQ-STC2-based S 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 and LabWindows/CVI, select
Help»Find Examples.
Measurement Studio, Visual Basic, and ANSI C examples are 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 NI-DAQ\Examples\
