PicoScope 7 Software
Available on Windows, Mac and Linux
(Python) AttributeError: 'Ps6000alib' object has no attribute 'DEFAULT_RESOLUTION'
(Python) AttributeError: 'Ps6000alib' object has no attribute 'DEFAULT_RESOLUTION'
Hello,
I am trying to set up communication with a 2204A, using Python 3.9 (64 bit) on Windows. I downloaded and installed the 64 bit PicoSDK, and I installed the GitHub python wrapper repo (https://github.com/picotech/picosdk-python-wrappers).
Following the Readme in that repo, I tried executing the verification code:
The import goes fine, but on the defintion of scopes it throws the error,
Is this a true bug, or did I miss something in the installation?
Any help would be greatly appreciated.

Update 20 April 2022:
After digging around the code in the repository, I find no mention or assignment of the DEFAULT_RESOLUTION attribute of Ps6000alib (class defined in picosdk/ps6000a.py). So, it must be defined at a lower level, which I am not comfortable playing around with.
I installed a second 2204A on a Linux system (w/ Python 3.7) and ran into the same error, so it is not a driver installation error on my part.
However, I found that everything works fine if line 22 in discover.py is commented out (see attached image). This indicates that the implementation (at the driver level?) of the 6000A series of oscilloscopes is different from the other series in a way that conflicts with how this Python library generally handles them.

I'm getting the same error. Running Python 3.12, with a PicoScope 2206B.
