Using Python Wrapper
Using Python Wrapper
Hi,
I managed to run tests using the example which comes with the wrapper.
How can I implement the test in my own project? Am I supposed to copy the whole repo as a directory in my repo?
I seem to need the picosdk package known to my python interpreter.
Thank you

Hi
You don't need to download the full repository but you will definitely need the picosdk folder from the repository which contains files that define the link between the API functions from the dll and how they are called within python.

Thanks!
I got it to work, the setup.py file malfunctions, the try...except there does not identify the library so removing it has made me install successfully.

Re: Using Python Wrapper
Hi,
There is still a problem with setup.py, and I don't know who to address this issue as there is no "Issues" tab on the github page.
The issue is that ctypes.WinDLL returns an exception in setup.py, even if the file ps2000.dll exists where it is being looked for, so if I comment out the whole section trying to locate the dll file, the package is installed and I can use it.
Here is the modified setup.py I was using, on two separate Windows 10 machines:
