Hi

I have to access data from 'n custom electronic card to matlab via the usb port.

When loading the external dll using:

[notfound, warnings] = loadlibrary ('ftd2xx','ftd2xx')

notfound =

Empty cell array: 0-by-1

warnings =

Bitfields are unsupported in structures. Structure s_FTCOMSTAT skipped. Found on line 1061 of input from line 1096 of file d:\..\ftd2xx.h

Bitfields are unsupported in structures. Structure s_FTDCB skipped. Found on line 1092 of input from line 1127 of file d:\..\ftd2xx.h

Now I am not sure if these warnings are the problem or not but when I try to add variable related to a typedef I get this:

ftHandle = libstruct ('PVOID') ??? Error using ==> feval Undefined function or variable 'lib.PVOID'.

Error in ==> libstruct at 15 ptr=feval(['lib.' structtype]);

What am I doing wrong?

Total longshot, but did this ever get resolved? running into a similar issue with loadlibrary.
