Installation

Python requirements

rtd-acquire 0.2.0 requires Python 3.11 or newer.

Install the current release from PyPI:

python -m pip install rtd-acquire

The base package has no required runtime dependencies.

Raspberry Pi / Linux SPI extra

The Linux SPI adapter uses the optional spidev package:

python -m pip install "rtd-acquire[raspberry-pi]"

The extra installs the Python backend; it does not enable SPI in the operating system or configure your wiring.

Development checkout

The project uses uv for its development environment:

git clone https://github.com/GregRR/rtd-acquire.git
cd rtd-acquire
uv sync

Include the Raspberry Pi extra when developing against Linux SPI:

uv sync --extra raspberry-pi

rtd-sensor is separate

rtd-sensor is intentionally not an rtd-acquire dependency. Install it separately if your application also needs resistance-to-temperature conversion or RTD-model interpretation:

python -m pip install rtd-sensor

This keeps acquisition software usable without choosing a specific RTD model.
