Unable to install using pip

[fdanapfel]

Hello,

I just got an isdt N8 charger and wanted to be able to read the data from it on my computer, but unfortunately the manufacturer doesn't provide any tools for this.

After some searching I discovered this project, but unfortunately I wasn't able to install it using the provided instructions.

Running "pip install isdttool" results in the following error:

$ pip install isdttool

  note: This error originates from a subprocess, and is likely not a problem with pip.

I tried this on macOS 10.15, Fedora 37 and also Raspberrypi OS 11 (bullseye), and on all of them I get the same error.

After some searching I was able to get isdttool installed by changing the install_requires statement in the setup.py as follows:

install_requires=['hidapi>=0.10.1'],

Now the installation runs trough:

$ python3 ./setup.py install
running install

Unfortunately it is not possible to read any data from the N8:

$ isdttool list
