kontron / python-aardvark Goto Github PK

Hi,

Total Phase officially released the new API (v6.00). Could you please also make an update? Thanks very much!
Here is the link: https://www.totalphase.com/products/aardvark-software-api/#
We verified this new API version, and it did solved the issue we observed on the latest Ubuntu 22.04.

Thanks!

I installed with 'easy_install pyaardvark' on Yosemite and get the following error:

import pyaardvark

File "build/bdist.macosx-10.10-intel/egg/pyaardvark/init.py", line 22, in

File "build/bdist.macosx-10.10-intel/egg/pyaardvark/aardvark.py", line 52, in
RuntimeError: Unable to find suitable binary interface. Unsupported platform?

Is it not supported on Yosemite? Or am I missing something I need.

Thanks,
Frank

For using python-aardvark under windows use v2.16.

See also kontron/python-ipmi#95

instead of the port number let the user supply a serial number, too.

hi,

I installed the pyaardvark in pycharm of version 0.6.1, when i import this API, an error message came up as below:
my python version is 3.7, how can i update to your new version?

I was fighting with this one recently and finally sorted it out with some help from the PyInstaller devs and some info from Total Phase. I wanted to mention it here so it could be documented for future users, especially if someone updates to newer pyaardvark versions.

The newest versions of the aardvark.dll, from version 5.60+, now have a python3.dll requirement baked into them. This seems to manifest into a few odd issues, particularly the popup messages of "OSError: [Errno -2] unable to load usb driver" and "Unable to bind API".

This error comes from one of two different sources, from what I've seen.

• The python version is incompatible with the aardvark.dll version
• There is an issue with detection of python3.dll

For PyInstaller specifically, the python3.dll isn't being included automatically in the build, so I get the errors above depending on which version of pyaardvark I'm running. The instructions to correct for this can be found here: pyinstaller/pyinstaller#7326 (comment)

If you know you have the correct python version and are seeing one of these errors, it may be related to the python3.dll not being detected, especially if you are running a separate program that is interfacing with python to run your code, rather than directly in the interpreter.

Hi, I tried to run an example code as below `import aardvark_py as a

a.aa_find_devices(1)

handle = a.aa_open(0)

print(a.aa_features(handle))

a.aa_close(handle)`

But I am getting an error as below. Are any dependencies missing/not available for an M1 Mac at the moment?

I have successfully imported pyaardvark however when i try to run the code below:

`import pyaardvark

a = pyaardvark.open()`

i get the errors below:

Any ideas??

Hi,
I really like this project, and I am sure I could contribute.

I have done work (outside of github) on converting python projects to be python 2/3 agnostic.
But I havn't done any DLL communication or anything like that.

So what I am saying is, if I submit a pull request containing updates to python3, would somebody be willing to ensure that the python3 executable works with the aardvark dll?

I've been using this library in a project quite successfully (thanks for making it easy to use!), but I've noticed that sometimes I2C writes don't go through and the API does not provide any indication of this. (There are multiple masters in my system, so probably it's losing arbitration.)

The root cause seems to be that Aardvark.i2c_master_write treats the return value of aa_i2c_write as a status code, when that function actually returns the number of bytes written. Therefore some exception should be raised whenever the return value is less than len(data). Or even better, use aa_i2c_write_ext which actually does return a status code (I'd really like to know if SLA_ACK, SLA_NACK, DATA_NACK, or ARB_LOST statuses occur).

Hi there,

I noticed that opening the device fails with an IO Error (device in use) whenever using pyaardvark from a remote session (SSH or Remote desktop).

Does the library depend on some environment variable not defined in remote sessions? Any hint/workaround?
