Note that this package is intended to run on a Raspberry Pi with a particular hardware configuration.
See the hardware configuration for the device's wiring configuration.
Enable I2C interface via Raspi-Config under Interface Options.
sudo raspi-config
Ensure virtual environments can be created
sudo apt install python3-venv
Recommended(!!): Create a new environment.
python3 -m venv brainwasher
Enter the environment.
source ~/brainwasher/bin/activate
To use the software, in the root directory, run
pip install -e .
To develop the code, run
pip install -e .[dev]
If Python drivers were not installed automatically with the first command, you can install them manually from their respective repositories here:
There are two strategies for editing code on the Raspberry Pi.
Since the Raspberry Pi doesn't have all the text editing bells-and-whistles of your PC, you can develop all the code on your PC and synchronize the code folder with the Pi to execute the result.
To do so, in Linux, use the rsync
command
rsync -a /path/to/brainwasher pi@raspberrypi.local:/path/to/destination_folder --exclude=".*"
Then run
uv sync
Now you can avoid installing Github credentials to push code from the device itself, and simply develop entirely on your PC!
The Raspberry Pi 4 and 5 are fast enough that you can develop code on the Pi itself if needed. To do so, login to the Pi, setup Git, and edit files on the device itself.

There are several libraries used to run linters, check documentation, and run tests.
- Please test your changes using the coverage library, which will run the tests and log a coverage report:
coverage run -m unittest discover && coverage report
- Use interrogate to check that modules, methods, etc. have been documented thoroughly:
interrogate .
- Use flake8 to check that code is up to standards (no unused imports, etc.):
flake8 .
- Use black to automatically format the code into PEP standards:
black .
- Use isort to automatically sort import statements:
isort .
For internal members, please create a branch. For external members, please fork the repository and open a pull request from the fork. We'll primarily use Angular style for commit messages. Roughly, they should follow the pattern:
<type>(<scope>): <short summary>
where scope (optional) describes the packages affected by the code changes and type (mandatory) is one of:
- build: Changes that affect build tools or external dependencies (example scopes: pyproject.toml, setup.py)
- ci: Changes to our CI configuration files and scripts (examples: .github/workflows/ci.yml)
- docs: Documentation only changes
- feat: A new feature
- fix: A bugfix
- perf: A code change that improves performance
- refactor: A code change that neither fixes a bug nor adds a feature
- test: Adding missing tests or correcting existing tests
The table below, from semantic release, shows which commit message gets you which release type when semantic-release
runs (using the default configuration):
Commit message | Release type |
---|---|
fix(pencil): stop graphite breaking when too much pressure applied |
|
feat(pencil): add 'graphiteWidth' option |
|
perf(pencil): remove graphiteWidth option BREAKING CHANGE: The graphiteWidth option has been removed. The default graphite width of 10mm is always used for performance reasons. |
(Note that the BREAKING CHANGE: token must be in the footer of the commit) |
To generate the rst files source files for documentation, run
sphinx-apidoc -o doc_template/source/ src
Then to create the documentation HTML files, run
sphinx-build -b html doc_template/source/ doc_template/build/html
More info on sphinx installation can be found here.
