NI-DAQ Driver Software

The NI-DAQ driver software is included at no charge with all National 
Instruments DAQ hardware. NI-DAQ has an extensive library of functions 
that you can call from your application programming environment. These 
functions include routines for analog input (A/D conversion), buffered data 
acquisition (high-speed A/D conversion), analog output (D/A conversion), 
waveform generation, digital I/O, counter/timer operations, SCXI, PXI 
Trigger Bus (RTSI), self-calibration, messaging, and acquiring data to 
extended memory.

NI-DAQ also internally addresses many of the complex issues between the 
computer and the plug-in board, such as programming interrupts and DMA 
controllers. NI-DAQ maintains a consistent software interface among its 
different versions so that you can change platforms with minimal 
modifications to your code. Whether you are using conventional 
programming languages or National Instruments application software, your 
application uses the NI-DAQ driver software, as illustrated in Figure 1-1.
