Summary

LIS3MDL 3-axis magnetic compass with SPI interface for detecting magnetic fields and orientation.

Description

The **LIS3MDL Magnetic Compass (SPI)** measures the X, Y, and Z components of magnetic fields. It supports configurable sample rates, full-scale range, power modes, self-test, and temperature compensation. Performance modes for XY and Z axes can be individually set. The sensor communicates via SPI and can be reset or synchronized using a clock input.

Properties

• Enabled – Enables or disables the compass.
• Fast Rate (boolean) – Enables faster measurement rates.
• Full Scale Range (Gauss) – Measurement range (default 4 Gauss).
• Low Power Mode (boolean) – Reduces power consumption.
• Power Down (boolean) – Puts sensor in power-down mode.
• Sample Rate (Hz) – Frequency of measurements (default 20 Hz).
• Self Test (boolean) – Enables self-test mode.
