Installation

Stable release

To install HVL Common Code Base, run this command in your terminal:

$ pip install hvl_ccb

To install HVL Common Code Base with optional Python libraries that require manual installations of additional system libraries, you need to specify on installation extra requirements corresponding to these controllers. For instance, to install Python requirements for LabJack and TiePie devices, run:

$ pip install "hvl_ccb[tiepie,labjack]"

See below for the info about additional system libraries and the corresponding extra requirements.

To install all extra requirements run:

$ pip install "hvl_ccb[all]"

This is the preferred method to install HVL Common Code Base, as it will always install the most recent stable release.

If you don’t have pip installed, this Python installation guide can guide you through the process.
