sensor_imu_format_t

Data payload format for data of type SENSOR_FORMAT_IMU

Synopsis:

#include <sensor/sensor_api.h>
typedef struct sensor_imu_format_t {
    int32_t orientation[3];
    uint32_t orientation_time_offset;
    int32_t acceleration[3];
    double rate_of_turn[3];
    double magnetic_field[3];
    uint32_t time_offset;
    uint32_t time_accuracy;
    uint16_t ndop;
    uint16_t edop;
    uint32_t heading_accuracy;
} sensor_imu_format_t;

Data:

int32_t orientation[3]
Orientation is the three Euler angles, in hundreds of degrees, about x (roll), y (pitch), and z (yaw) axes; the coordinate system is ENU.

MAX_INT32 indicates value is currently unavailable.

uint32_t orientation_time_offset
Offset from the timestamp in sensor_buffer_t to apply for the orientation field only.

Time is provided in microseconds and may be zero if orientation is in sync with IMU data.

int32_t acceleration[3]
Acceleration in the x, y, and z planes in mm/s^2.
double rate_of_turn[3]
Rate of turn about the x, y, and z axes in radians per second.
double magnetic_field[3]
Magnetic field data in arbitrary units.
uint32_t time_offset
Offset from the timestamp in sensor_buffer_t to apply for this data point.
uint32_t time_accuracy
Time accuracy estimate in ns.
uint16_t ndop
Northing Degree of Precision.
uint16_t edop
Easting Degree of Precision.
uint32_t heading_accuracy
Heading accuracy estimate, in degrees.

Library:

libsensor

Description:

The payload in data of sensor_buffer_t is an array of these data points.
