Arduino Toolkit - bno055
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.readTemperatureSee 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
readVal - the 3 magnetic field values
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) Read the sensor calibration status
Inputs
obj - the sensor object
Outputs
status - structure containing the calibration information.
Structure fields are:
- System
System calibrarion
- Accelerometer
Accelerometer calibration status
- Gyroscope
Gyroscope calibration status
- Magnetometer
Magnetometer calibration status
Values for each will be either ’uncalibrated’, ’partial’ or ’full’.
- :
inf =info(obj) Read the sensor info
Inputs
obj - the sensor object
Outputs
inf - structure containing the sensor information.
Structure fields are:
- Version
Software firmware version
- SensorId
sensor id value
- Type
sensor type ’bno055’
