Arduino_BOSCH_BMM150

This is an Arduino library for the BOSCH BMM150 magnetometer like it is used in the Arduino Nano 33 BLE Sense. The library supports several ways of reading the sensor data,

This library uses the BOSCH BMM150 Sensor API.

Usage

Object creation

#include "bosch_bmm150.h"
andrgrue::sensor::bosch_bmm150 Mag(Wire1);

float mag_x, mag_y, mag_z;
andrgrue::sensor::bosch_bmm150::Data mag_data;

Setup

void setup() {

  // wire must be initialized first
  Wire1.begin();
  Wire1.setClock(400000);

  if(!Mag.initialize(BMM150_DATA_RATE_25HZ)) {
    Serial.println("MAG init failed!");
    while (1);
  }

  Serial.print("sample rate: mag=");
  Serial.println(Mag.magneticfieldSampleRate());
}

Loop

void loop() {

  if(Mag.magneticfieldAvailable()){
    Mag.magneticfield(mag_data);
  }

}
