Installation

Operating System	Download
🪟 Windows (64 bit)
🐧 Linux	pip install hvlbuzz
🍏 Mac	pip install hvlbuzz

Development setup

It is recommended that you use a Python virtual envioronement to run HVLBuzz. Run the following command to create folder called kivy_venv inside which your environement will live. The latest version of Python this code has been tested with was 3.10

python -m venv kivy_venv

Activate your virtual environement by running

kivy_venv\Scripts\activate.bat # 🪟
. kivy_venv/bin/activate # 🐧 / 🍏

Then install hvlbuzz into your environement as follows

pip install .
pip install garden.matplotlib/

This will also install an executable python script in your environments bin folder.

Usage

To run the binary obtained in the install part, run

hvlbuzz

Alternatively, the module is can also be started from python:

python -m hvlbuzz

or

python hvlbuzz

Compiling your own packaged version

The source code can also be compiled by yourself using PyInstaller using the provided hvlbuzz/buzz.spec file.

pyinstaller hvlbuzz/buzz.spec

A buzz.exe binary will be available in a (newly created if non-existing) dist\buzz folder.

Credits

Originally, HVLBuzz was developed by Aldo Tobler under the supervision of Christian M. Franck, Sören Hedtke and support by Mikołaj Rybiński at ETH Zurich's High Voltage Laboratory.

Currently, it is maintained by FKH Zürich.

This tool is completely free to use as is and only requires freely available Python libraries to run. The GUI is based on the Kivy framework, while the mathematical computations and plot generation rely the widely used NumPy and Matplotlib.
