Python tools for the Piksi GNSS receiver. This repository includes a a variety of command line utilities (firmware bootloader, serial port data logging, etc.).

It is advised to install piksi_tools inside a conda environment to avoid modifying global system state. To setup a conda environment first install Miniconda via your package manager if needed, and then run:

conda create -n piksi_tools python=3.7
conda activate piksi_tools

Run pip install -e .[test] to set up a dev install in the local dev environment.

• The most important command line tools - bootload_v3.py, fileio.py, serial_link.py, and settings.py - support Python 3.7 onward.

To run the tests and check for coverage:

$ PYTHONPATH=. tox

This by default attempts to run tests for all supported Python versions. To skip those versions that you don't have installed, run:

$ PYTHONPATH=. tox --skip-missing-interpreters

Finally, to run all tests for all supported Python versions:

$ PYTHONPATH=. tox -e py37

To release this project, run the following:

# ... Or, activate your appropriate conda environment ...
conda activate piksi_tools
pip install build
python -m build --wheel
python -m build --sdist
pypi upload -u $PYPI_USER -p $PYPI_PASS dist/*

The ftdi USB drivers are finicky on some versions of OS X. See their docs for help debugging (tl;dr if you try to plug in multiple USB devices to the same port, the subsequent ones may not appear through ftdi even if they appear in the result of sudo dmesg. Only restarting your machine will fix this.)
