I am testing an evalution software of LabWindows/CVI. I want to develop a little program wich analyse the electronical signal of a card that I realised. For this, I need a driver which etablish the interface between this component and my program, how I can realise it ?
If I understand correctly, you developed some plug in hardware and you want to access it with CVI. Usually there would a be a driver created for the device that would be encapsulated as a DLL that you can call directly.
Another thing to take into account is that Windows NT/2000/XP will not allow direct memory or port acces without going into kernel mode, which is not easy. CVI has a set of functions that can help you access memory locations or ports.
The functions that you would use are under the "Utility library>> Port IO and Physical Memory access" CVI provides a driver that will allow this functions to work even in new Windows systems.
