Syntax

[tempReading,timestamp] = readTemperature(sensor)

Description

[tempReading,timestamp] = readTemperature(sensor) returns one sample of the ambient temperature data from the BMI160 sensor. The ambient temperature sample is returned as a scalar in degree Celsius. The function also returns the timestamp at which MATLAB® receives the temperature data from the BMI160 sensor. The timestamp output is optional.

Note

To generate C/C++ code for this function, you must have an Embedded Coder® license.

Read the ambient temperature data from the BMI160 sensor.

Create a connection from MATLAB to the Raspberry Pi® hardware board.

mypi = raspi;
mypi = 

  Raspi with Properties:

           DeviceAddress: 'raspberrypi-hysdu8X38o'
                    Port: 18734
               BoardName: 'Raspberry Pi 3 Model B+'
           AvailableLEDs: {'led0'}
    AvailableDigitalPins: [4,5,6,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27]
    AvailableSPIChannels: {‘CE0’,’CE1’}
       AvailableI2CBuses: {'i2c-1'}
             I2CBusSpeed: 100000
        AvailabelWebCams: mmal service 16.1 (platform:bcm2835-v4l2)

Create an bmi160 sensor object on the I2C bus 'i2c-1' on address '0x5F'.

sensor = bmi160(mypi,'Bus','i2c-1');
sensor = 

  bmi160 with properties:

                         I2CAddress: 95 ("0x5F")
                                Bus: i2c-1

Return one sample of ambient temperature data read from the BMI160 sensor.

[tempReading,timestamp] = readTemperature(sensor);
tempReading =

  data

    23.4384

timestamp = 

  datetime

   22-Dec-2020 17:23:09.934

Since the timestamp output is optional, you can obtain only the ambient temperature data from the BMI160 sensor.

[tempReading] = readTemperature(sensor);
tempReading =

  data

    23.4384

Input Arguments

collapse all

BMI160 sensor object connection to the Raspberry Pi hardware board, specified as a bmi160

Example: sensor = bmi160(mypi) creates a connection to the BMI160 sensor on the Raspberry Pi object mypi.

Output Arguments

collapse all

Read the ambient temperature data from the BMI160 sensor.

Read the date and time at which MATLAB receives the ambient temperature sample value from the BMI160 sensor, specified as a datetime.
