Driver for the BNO055 9DOF IMU sensor.

acceleration

Gives the raw accelerometer readings, in m/s.

accelerometer

Gives the raw accelerometer readings, in m/s.

Warning

This is deprecated. Use acceleration instead. It’ll work with other drivers too.

euler

Gives the calculated orientation angles, in degrees.

external_crystal

Switches the use of external crystal on or off.

gravity

Returns the gravity vector, without acceleration in m/s.

gyroscope

Gives the raw gyroscope reading in degrees per second.

linear_acceleration

Returns the linear acceleration, without gravity, in m/s.

magnetic

Gives the raw magnetometer readings in microteslas.

magnetometer

Gives the raw magnetometer readings in microteslas.

Warning

This is deprecated. Use magnetic instead. It’ll work with other drivers too.

mode

Switch the mode of operation and return the previous mode.

Mode of operation defines which sensors are enabled and whether the measurements are absolute or relative:

Mode Accel Compass Gyro Absolute
CONFIG_MODE
ACCONLY_MODE X
MAGONLY_MODE
X
GYRONLY_MODE
X
ACCMAG_MODE X X
ACCGYRO_MODE X
X
MAGGYRO_MODE
X X
AMG_MODE X X X
IMUPLUS_MODE X
X
COMPASS_MODE X X
X
M4G_MODE X X
NDOF_FMC_OFF_MODE X X X X
NDOF_MODE X X X X

The default mode is NDOF_MODE.

quaternion

Gives the calculated orientation as a quaternion.

reset()[source]

Resets the sensor to default settings.

temperature

Measures the temperature of the chip in degrees Celsius.

use_external_crystal

Switches the use of external crystal on or off.
