mobbo-serial 0.1.0

Serial COP (center of pressure) library for two-force-board setups - connect, tare, and record sessions to CSV, no GUI required.

mobbo

GUI-free Python library for the two-force-board COP (center of pressure) serial device. Connect over a COM port, get live per-board and combined COP samples, tare, and record sessions to CSV.

Install

pip install mobbo-serial
# or: uv add mobbo-serial

sample_gui.py (a PySide6 demo app built on this library) needs the optional gui extra:

pip install mobbo-serial[gui]

Usage

import mobbo

# optional: relocate where session data is saved (defaults to
# <Documents>/mobbo-data, config lives at ~/.mobbo/config.json)
mobbo.configure(data_dir="D:/lab-data")

board = mobbo.Board(port="COM10", layout="side_by_side")
board.on_sample(lambda s: print(s.combined.cop_x, s.combined.cop_y))
board.connect()

board.tare()  # blocks briefly, zeroes current load as baseline

session_dir = board.start_recording("subject1")
# ... let it run ...
csv_path = board.stop_recording()
print(f"saved to {csv_path}")

board.disconnect()

mobbo.list_ports() lists available COM ports.

Development

uv sync --extra gui  # --extra gui only needed to run sample_gui.py
uv run pytest -v

Releasing

Publishing to PyPI is automated: bump version in pyproject.toml, commit, tag it (git tag vX.Y.Z && git push origin vX.Y.Z), then publish a GitHub Release for that tag - the publish.yml workflow builds and uploads it via PyPI Trusted Publishing.
