I want to design a " Data Acquistion Card" with PCI interface,and want to drivedand process output data in labview, But I don't know whether Labview has this function to drive or read/write this kind of Data Acquisition Card which designed by myself not by NI company.
What you use in LabVIEW will depend on what type of low level driver you write. LabVIEW has the Call Library Function Node for calling a DLL, the C Interface Node, Active X, and .NET functions. You can even use VISA and do register reads and writes.
