Programming Devices in Software
National Instruments measurement devices for USB 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 NI-DAQmx, which has its own API, hardware
configuration, and software configuration. Refer to the NI-DAQmx for USB
Getting Started Guide for more information.
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.
