Programming Devices In Software - National Instruments USB-621 Series User Manual

Programming Devices in Software

© National Instruments Corporation
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.
USB-621x devices use the NI-DAQmx driver. 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, LabWindows/CVI. Measurement Studio, Visual
Basic, and ANSI C examples, refer to the KnowledgeBase document,
Where Can I Find NI-DAQmx Examples?, by going to
