Discussion - Software / FT4222 Python Interface
« on: January 12, 2021, 12:22:17 PM »
Hey,

I am working on an interface for FTDI devices based on the provided api (dlls ftd2xx64.dll + LibFT4222-64.dll in this case). I implemented the basic functions to open a device, read the usb desciptors ect. Everything went well, every function returns FT_OK!
Then I went to get the device specific system layer working, in this case it was porting all functions from LibFT4222-64.dll
Now every function from the API just returns 1000... First I thought I had some issue with the device handle but after I tryed almost everything I decided to change to 32-Bit.
So I used a 32-Bit Python and the correcponding 32-Bit dlls ftd2xx.dll + LibFT4222.dll

Now the same code works... So I think there is an issue with the 64 Bit Library of the FT4222...
Did you had such issues before?

Best regards


INFO: I am using windows 10 64 Bit
