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 8.x includes two NI-DAQ drivers, Traditional NI-DAQ (Legacy)
and NI-DAQmx. 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.

Traditional NI-DAQ (Legacy) and NI-DAQmx each include 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.
