Hi,

I have written a driver for a device I am making and need to interface the device with MATLAB. Essentially the driver is a kernel mode Windows driver written around WDF. I can already access the driver using the Windows APIs: "GetDevicePath()", "CreateFile()", "WriteFile()" and "ReadFile()" from a C++ program.

So the question is, is there a MATLAB equivalent to the aforementioned functions? If not how is the best way to go about this?

Thanks.

Hi Tom, my initial thoughts would be to investigate one of the following:

a) write a C/C++ dll API for your driver, and then load it into MATLAB using LOADLIBRARY.

b) write a .NET assembly API for your driver, and then use MATLAB's ability to load .NET assemblies.

c) write a MEX function to control the driver directly via WDF Windows APIs.

I would lean towards option a), because that way you will end up with a C/C++ DLL that you can reuse in other contexts/languages, and calling DLL functions in MATLAB using LOADLIBRARY is very painless.

I hope that helps :)
