bitalino-rs

Rust driver and Python bindings for BITalino biosignal acquisition devices. This project automates Bluetooth pairing/connection (RFCOMM), exposes a safe Rust API, and ships Python wheels for easy use in data pipelines.

Quick Links

• Docs: tleygue.github.io/bitalino_rs (published via GitHub Pages; sources in docs/)
• Python package: bitalino_rs (built with maturin, published from tags)
• Crate: bitalino-rs (Rust library)

Features

• Connect to BITalino over Bluetooth without root privileges (automatic pair + bind).
• High-level Rust API plus generated Python bindings via PyO3/maturin.
• Timing-aware reads with sequence numbers, CRC tracking, and batch timestamps.
• Minimal dependencies; Ubuntu support verified in CI.

Project Layout

• src/ – Rust library (Bluetooth, driver, Python bindings)
• bitalino_rs/ – Python package stub for maturin builds
• docs/ – User/developer docs (mkdocs)
• .github/workflows/ – CI, release, PyPI publish

Install

Python (from PyPI, when released)

uv pip install bitalino-rs

Python (from source)

Requirements: Rust (stable), Python 3.11+, system deps (libdbus-1-dev libudev-dev on Ubuntu).

# in repo root
uv sync

Rust crate (from source)

cargo build --release

Usage

Rust

use bitalino_rs::{Bitalino, SamplingRate};

fn main() -> Result<(), Box<dyn std::error::Error>> {
		let mut dev = Bitalino::connect("7E:91:2B:C4:AF:08", "1234")?;
		dev.start(SamplingRate::Hz1000 as u16, Some(vec![0, 1, 2]))?;
		let frames = dev.read_frames(100)?;
		println!("read {} frames", frames.len());
		dev.stop()?;
		Ok(())
}

Python

from bitalino_rs import Bitalino

dev = Bitalino.connect("7E:91:2B:C4:AF:08")
dev.start(rate=1000, channels=[0, 1, 2])
batch = dev.read_timed(200)
print(batch.timestamp_us, batch.sequence_gaps)
dev.stop()

Development

• Rust toolchain: rustup toolchain install stable (CI uses stable with rustfmt/clippy)
• System deps (Linux): sudo apt-get install -y pkg-config libdbus-1-dev libudev-dev
• Lint/format: pre-commit run --all-files
• Commit style: Conventional Commits (checked in CI)
• Tests: cargo test --all-features --all-targets
