Let’s install pyusb and lsusb

pip3 install pyusb
brew install libusb

Install Python Drivers

First, unzip the stellarnet driver library. Second, go to the unzipped folder. 

Then check what the Python version is

conda activate
python --version

The driver files for macOS are located in the stellarnet_driverLibs/ folder and have the .darwin.so extension. Choose the correct file based on your Python version:

• Python 3.7 → stellarnet_driver3.cpython-37m-darwin.so

• Python 3.8 → stellarnet_driver3.cpython-38-darwin.so

• Python 3.9 → stellarnet_driver3.cpython-39-darwin.so

• Python 3.10 → stellarnet_driver3.cpython-310-darwin.so

• Python 3.11 → stellarnet_driver3.cpython-311-darwin.so

• Python 3.12 → stellarnet_driver3.cpython-312-darwin.so

If Python version is 3.12 for example, 

cd Python_StellarNet_Driver_2-6/
cp stellarnet_driverLibs/stellarnet_driver3.cpython-312-darwin.so stellarnet_driverLibs/stellarnet_driver3.so

Make sure to add the driver as a trusted application of your system.

sudo xattr -rd com.apple.quarantine stellarnet_driverLibs/stellarnet_driver3.cpython-312-darwin.so

Permanently add the driver to your PYTHONPATH

echo 'export PYTHONPATH=$PYTHONPATH:/Users/pandora_ctrl/Desktop/Python_StellarNet_Driver_2-6/stellarnet_driverLibs' >> ~/.zshrc
source ~/.zshrc

Or add to the PYTHONPATH temporarily.

export PYTHONPATH=$PYTHONPATH:/Users/pandora_ctrl/Desktop/Python_StellarNet_Driver_2-6/stellarnet_driverLibs

Check if the installation is working.

python3 -c "from stellarnet_driver3 import *"

Run the demo python script to make sure your code is working properly.

Not setting up a python path

If you do not want to add the stellarnet path to your python you should add the python path before importing the module. 

import os
import sys

# Ensure the driver directory is in the Python path
driver_path = os.path.join(os.getcwd(), "stellarnet_driverLibs")
sys.path.append(driver_path)

# Import the driver
from stellarnet_driverLibs import stellarnet_driver3 as sn

# Test the driver version
print("StellarNet Driver Version:", sn.version())
