Detailed Description

Sensor value data structure types based on common data types.

Suitable for common sensors, such as IMU, Light sensors and orientation sensors.

Sensor value data structure for 3-axis sensors. struct sensing_sensor_value_3d_q31 can be used by 3D IMU sensors like: SENSING_SENSOR_TYPE_MOTION_ACCELEROMETER_3D, SENSING_SENSOR_TYPE_MOTION_UNCALIB_ACCELEROMETER_3D, SENSING_SENSOR_TYPE_MOTION_GYROMETER_3D, q31 version

Field Documentation

◆ header

struct sensing_sensor_value_header sensing_sensor_value_3d_q31::header

Header of the sensor value data structure.

◆

struct { ... } sensing_sensor_value_3d_q31::readings[1]

Array of readings.

◆ shift

int8_t sensing_sensor_value_3d_q31::shift

The shift value for the q31_t v[3] reading.

◆ timestamp_delta

uint32_t sensing_sensor_value_3d_q31::timestamp_delta

Timestamp delta of the reading.

Unit is micro seconds.

◆ v

q31_t sensing_sensor_value_3d_q31::v[3]

3D vector of the reading represented as an array.

For SENSING_SENSOR_TYPE_MOTION_ACCELEROMETER_3D and SENSING_SENSOR_TYPE_MOTION_UNCALIB_ACCELEROMETER_3D, the unit is Gs (gravitational force). For SENSING_SENSOR_TYPE_MOTION_GYROMETER_3D, the unit is degrees.
