Arduino Library

The Soldered BMM350 Geomagnetic Sensor library talks to the breakout over I2C. Include BMM350-SOLDERED.h and create a Soldered_BMM350 object. Its begin() sets the sensor to 100 Hz with 4-sample averaging, enables all three axes and starts normal mode, so getSensorData() returns compensated readings in µT straight away.

Functionality

Each page starts with one verified library example and explains every function the example uses to get that result.
