magnetometer 0.2.1

No project description provided

Magnetometer

This is a magnetometer command-line tool that reads from physical magnetic sensors via Belay.

Installation

Install Magnetometer through pip:

pip install magnetometer

Usage

To start the program, invoke magnetometer along with the port your CircuitPython board is connected to.

magnetometer DEVICE_PORT --sensor SENSOR_TYPE

You can use the debugging sensor sin without any physical hardware interactions. CircuitPython must be installed on-device and must be configured with rw storage. Magnetometer will automatically upload all necessary code to device. Run magnetometer --help to see more options.

Supported Sensors

• LIS3MDL - Up to ±1,600μT
• MMC5603 - Up to ±3,000μT
• LIS2MDL - Up to ±5,000μT
• TLV493D - Up to ±130,000μT

Want to support another sensor? Open an issue (or even a PR) on Github and we can try to add it!

Acknowledgements

This tool uses many awesome libraries that keep the implementation terse and the outputs beautiful:

• Belay - Seameless python/hardware interactions. Used for all hardware interactions.
• AutoRegistry - Automatic registry design-pattern library for mapping names to functionality. Used to manage sensor hardware abstraction layer.
• Textual - Text User Interface framework for Python inspired by modern web development. Used for dynamic user input.
• Rich - Python library for rich text and beautiful formatting in the terminal. Used for general UI text rendering.
• AsciiChartPy - Nice-looking lightweight console ASCII line charts. Used for chart plotting. Modified to be rich-compatible.
• CircuitPython Bundle - A bundle of useful CircuitPython libraries ready to use from the filesystem.
