Package nidaqdev

Class Nidaq

java.lang.Object

nidaqdev.Nidaq

public class Nidaq
extends Object

Nidaq is is a wrapper style class, which makes calls to native C++ functions within in a .dll library. Each of the native C++ methods, corresponds very closely to a library call in NIDAQmx. It is by no means a complete wrapper for NIDAQmx and currently only contains those calls useful to the PAMGUARD project www.pamguard.org invalid input: '<'p
