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.
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.
