Detailed Description

A class to represent a BNO055 IMU.

Objects of this class can modify fusion modes of IMU, retrieve calibration status from the IMU, write/retrieve calibration coefficients, read Euler angles, and read angular velocity from the IMU.

Constructor & Destructor Documentation

__init__()

def BNO055_05.BNO055_05.__init__	(		self,
		pyb.I2C	i2c,
			device_addr
	)

Creates a new BNO055 object.

Initialized the BNO055 object with the connected pins.

Parameters

i2c	a pyb.I2C object to connect to the BNO055 device
device_addr	The device address (often in hex)

Member Function Documentation

calibration_status()

def BNO055_05.BNO055_05.calibration_status

(

self

)

Returns the calibration status bytes from the IMU.

Returns

Dictionary of calibration status values

change_op_mode()

def BNO055_05.BNO055_05.change_op_mode	(		self,
			op_mode
	)

Changes the operation mode to one of many fusion modes.

By passing an operation mode constant (IMU_MODE, COMPASS_MODE, M4G_MODE, MDOF_FMC_OFF_MODE, MDOF_MODE) change the operating mode of the IMU by writing to memory.

Parameters

op_mode

The operating mode constant to set the device in. (IMU_MODE, COMPASS_MODE, M4G_MODE, MDOF_FMC_OFF_MODE, MDOF_MODE)

read_angular_velocity()

def BNO055_05.BNO055_05.read_angular_velocity

(

self

)

Returns the angular velocities from IMU.

Returns the angular velocities from the IMU in degrees per second.

Returns

data A dictionary of angular velocities. No units specified.

read_calib_coeff()

def BNO055_05.BNO055_05.read_calib_coeff

(

self

)

Returns the calibration coefficients of the IMU.

Returns the calibration coefficients of the IMU as an array of packed binary data

Returns

Returns calibration coefficients as packed binary data

read_euler_angles()

def BNO055_05.BNO055_05.read_euler_angles

(

self

)

Returns the Euler angles from the IMU.

Returns the Euler angles from the IMU as dictionary

Returns

data A dictionary of Euler angle values converted into degrees.

write_calib_coeff()

def BNO055_05.BNO055_05.write_calib_coeff	(		self,
			data
	)

Writes the packed binary calibration coefficients to the IMU.

Takes calibration coefficients passed as data as an argument and writes to the IMU

Parameters

data	Packed binary data containing the calibration coefficients for the IMU
