First-time Setup

Linux / macOS

In a Terminal:

$ scripts/setup-virtual-env.sh
$ scripts/install-libs.sh

Windows

In PowerShell:

PS> python -m venv venv
PS> scripts\install-libs.bat

How to use

The *_standalone.py python programs can be run directly using Python, as long as their dependencies are installed.

The other applications and examples are written in Python 3, so you should set up a virtual python environment for their use, see First-time Setup above. The tools are located in the src directory. See the individual source files for instructions on usage.

To use the USB Detector, enter the python virtual environment and run the app in the subfolder:

Linux / macOS

In a Terminal:

$ source venv/bin/activate
$ python src/usb_detector.py

Windows

In PowerShell:

PS> venv\Scripts\activate.ps1
PS> python src\usb_detector.py
