Python Driver for Sensirion SHDLC Devices

This repository contains the base driver for Sensirion SHDLC devices as a Python package. For details, please read the package description in README.rst.

Usage

See package description in README.rst and user manual at https://sensirion.github.io/python-shdlc-driver/.

Development

We develop and test this driver using our company internal tools (version control, continuous integration, code review etc.) and automatically synchronize the master branch with GitHub. But this doesn't mean that we don't respond to issues or don't accept pull requests on GitHub. In fact, you're very welcome to open issues or create pull requests :)

Check coding style

The coding style can be checked with flake8:

pip install -e .[test]  # Install requirements
flake8                  # Run style check

Run tests

Unit tests can be run with pytest:

pip install -e .[test]                          # Install requirements
pytest -m "not (needs_serialport or needs_tcp)" # Run tests without hardware
pytest                                          # Run all tests

To run the tests which access connected hardware, you need to pass following arguments to pytest:

• --serial-port: The serial port where a device is connected (e.g. COM7)
• --serial-bitrate: The bitrate of the device connected to the serial port (e.g. 460800)
• --serial-address: The slave address of the device connected to the serial port (e.g. 0)
• --tcp-port: The TCP IP address where a device is connected (e.g. 192.168.100.209)
• --tcp-port: The port of the device connected via TCP (e.g. 10001)
• --tcp-address: The slave address of the device connected via TCP (e.g. 0)

Build documentation

The documentation can be built with Sphinx:

python setup.py install                        # Install package
pip install -r docs/requirements.txt           # Install requirements
sphinx-versioning build docs docs/_build/html  # Build documentation
