Hi,
I am using FT4232H-56Q and I have a problem with functions from D2XX. I am trying to open the device using the FT_OpenEx function. When the program is executed, after calling the FT_OpenEx function, I get 0 instead of ftHandle (the address) and the error "LabVIEW: (Hex 0x19) External code not present." I have no idea what might be wrong. I had a problem with the dll functions before, but I solved it by changing the arguments of the function. I checked them again and I think they are correct. Has anyone had a similar problem? I will add that I use LabVIEW NXG.
I attach screenshots, gvi, dll and manual to d2xx.
