each directional axis (X, Y, and Z), use the sensor_get_field() function, discussed
below.
NOTE
Magnetic compass sensors generally require a calibration procedure to correct for the
local magnetic fields present in an actual device deployment. Without this calibration,
the heading information will not be accurate. See the compass_calibration example
application for an example of a manual calibration procedure.
7.5.1 Example code sequence
7.5.1.1 Definitions and declarations
#include "sensor.h"
sensor_t
sensor_data_t
compass_dev;
compass_data;
// device descriptor
// heading data from device
7.5.1.2 Sensor initialization
sensor_attach (&compass_dev, SENSOR_TYPE_COMPASS, 0, 0);
7.5.1.3 Sensor read
compass_data.scaled = true;
// read values in degrees and uTesla
sensor_get_field (&compass_dev, &compass_data);
7.5.1.4 Use data in application
int32_t
int32_t
app_direction
app_inclination
= compass_data.heading.direction;
// 0 to 360 deg
= compass_data.heading.inclination;
// -90 to +90 deg
int32_t
app_field_strength = compass_data.heading.strength;
// uTesla
uint32_t app_read_time
= compass_data.timestamp
7.6 Magnetic field strength
In addition to reading a compass heading, a magnetic compass sensor can be used
to obtain multi-axis measurements of the local magnetic field strength (intensity). The
function takes the following form:
sensor_get_field (&device, &mag_data);
where device is the device descriptor of the compass and mag_data is a
sensor_data_t structure to receive the magnetic field strength data.
Scaled magnetic field strength measurements are expressed in microteslas (μT).
When the function returns, the values can be read from the mag_data structure using
the “axis” fields ( axis.x, axis.y, axis.z ).
NOTE
Magnetic compass sensors generally require a calibration procedure to correct for the
local magnetic fields present in an actual device deployment. Without this calibration,
the field strength information will not accurately reflect the external environment of the
sensor. See the compass_calibration example application for an example of a manual
calibration procedure.
