: bno055 ¶

BNO055 9 axis orientation sensor

Methods

: obj = bno055(arObj) ¶

: obj = bno055(arObj, propertyname, propertyvalue ....) ¶

Constructor to create BME280 sensor

Inputs

arObj - the arduino parent object

propertyname, propertyvalue - optional property name, value pairs. Current known properties are: Current properties are:

I2CAddress

I2C address of the sensor (default 0x40)

Bus

I2C bus - 0 or 1 (default 0)

OperatingMode

Operating mode ’ndof’ or ’amg’

Outputs

obj - created object

Example

a = arduino()
sensor = bno055(a)

: [C, timestamp] = readTemperature(obj) ¶

Read the temperature

Inputs

obj - the sensor object

Outputs

C - read temperature in deg C.

timestamp - timestamp when read

Example

a = arduino()
s = bno055(a)
# get temp
temp = s.readTemperature

See also: bno055.

: [readVal, timestamp] = readAcceleration(obj) ¶

Read the acceleration rate

Inputs

obj - the sensor object

Outputs

readVal - the 3 acceleration values

timestamp - timestamp when read

: [readVal, timestamp] = readAngularVelocity(obj) ¶

Read the angular velocity

Inputs

obj - the sensor object

Outputs

readVal - the 3 angular velocity values

timestamp - timestamp when read

: [readVal, timestamp] = readMagneticField(obj) ¶

Read the magnetic field components

Inputs

obj - the sensor object

Outputs

timestamp - timestamp when read

: [readVal, timestamp] = readOrientation(obj) ¶

Read the oriientation components

Inputs

obj - the sensor object

Outputs

readVal - the 3 orientation values

timestamp - timestamp when read

: [readings, overrun] = read(obj) ¶

: [accel, gyro, mag, timestamp, overrun] = read(obj) ¶

: [accel, gyro, mag, orientation, timestamp, overrun] = read(obj) ¶

Read the sensor data

Inputs

obj - the sensor object

Outputs

accel - acceleration reading from sensor.

gyro - angular acceleration reading from sensor.

mag - magnetic field reading from sensor.

orientation - orientation reading from sensor.

timestamp - timestamp when read

overrun - overrun flag.

readings - table structure with fields for Timestamp, Acceleration, AngularVelocity, MagneticField, Orientation.

: inf = readCalibrationStatus(obj) ¶
