any way to mimic NI hardware for testing my LV program?

[GSR]

I write up a data acquisition for my friend, but I don't have the corresponding hardware to test. Any program that can mimic the hardware for me to test my program?

Thanks

You can create a simulated channel in daqmx

..or why don't you use an object oriented approach with simulated objects.

This is how I’ve solved it.

All instruments inherits from a VdTestInstrument-Base class

This class has child classes for every instrument type I need.

E.g. Power Supply, Digital Input units, Switches, Climate Chambers.

For every sub group of instrument e.g. the Label Printing-class, I create a Simulated class and then the real implementation classes in this example I have three different implementations for printing a label.

In every Simulation class I register this simulated object to a <SINGELTON> class I call “VdTestInstrumentSimulation”.

;-)

This class shows a dialog box where I can select which simulated objects to open.

The dialog box dynamically opens the “SimulationDialog” method in the simulated class that gives the user an interface to the Simulated object.

Here the user can monitor what is written to the object and also control what responses the object should report back when you do a e.g. Read function on the object.

E.g.

This is how I can simulate all instruments on my Rig, I also of cause create a simulated DUT unit so I can test my software completely before deploying it in production.

Cheers,

This is a very good information.
