libftdi Windows binary 64 bit

[Brian Estey]

Has any been able to get Xiaofan Chen's new libftdi windows build working
with Python 3.6 64 bit? The build works perfectly with Python 3.6 32 bit,
but when I import ftdi1 in the 64 bit version I get the classic
"ImportError: DLL load failed: The specified module could not be found."

Any suggestions?

-Estey

Interestingly it works for me. I am using Python.org download with
pywin32 extensions. Not so sure if that matters.

You need to put the libftdi 64bit dll and libusb 64bit dll in the
path where your Python installation can find.

The following is under a virtual environment. I have not tried
Python 3.6 32bit yet.

(playusb) c:\work\libftdi\libftdi\python\examples>python
Python 3.6.5 (v3.6.5:f59c0932b4, Mar 28 2018, 17:00:18) [MSC v.1900 64
bit (AMD64)] on win32
Type "help", "copyright", "credits" or "license" for more information.

You are right, I use another PC and I got the same problem as you.
Let me check again over the weekend.

I just uploaded a new packages with the hopefully working Python 3.6
64bit bindings, please try it. Thanks.
