readTemperature

Read one ambient temperature data sample from LSM6DSL sensor

Since R2021a

Syntax

[tempReading,timestamp] = readTemperature(sensor)

Description

[tempReading,timestamp] = readTemperature(sensor) returns one sample of the ambient temperature data from the LSM6DSL IMU 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 LSM6DSL sensor. The timestamp output is optional.

Examples

Read Ambient Temperature Data from LSM6DSL Sensor

Read the ambient temperature data from the LSM6DSL IMU 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 lsm6dsl sensor object on the I2C bus 'i2c-1' on addresses '0x6B'.

sensor = lsm6dsl(mypi,'Bus','i2c-1','I2CAddress','0x6B');

sensor = 

  lsm6dsl with properties:

                         I2CAddress: 107 ("0x6B")
                                Bus: i2c-1

Return one sample of ambient temperature data read from the LSM6DSL sensor.

[tempReading,timestamp] = readTemperature(sensor);

tempReading =

  data

    15.3398

timestamp = 

  datetime

   5-Jan-2021 11:35:17.279

Since the timestamp output is optional, you can obtain only the ambient temperature data from the LSM6DSL sensor.

[tempReading] = readTemperature(sensor);

tempReading =

  data

    15.3398

Input Arguments

sensor — LSM6DSL sensor object

lsm6dsl object

LSM6DSL sensor object connection to the Raspberry Pi hardware board, specified as a lsm6dsl object.

Example: sensor = lsm6dsl(mypi) creates a connection to the LSM6DSL sensor on the Raspberry Pi object mypi.

Output Arguments

tempReading — Ambient temperature values read from LSM6DSL sensor

scalar ambient temperature data

Read the ambient temperature data from the LSM6DSL sensor.

timestamp — Timestamp of ambient temperature values read from LSM6DSL sensor

datetime

Read the date and time at which MATLAB receives the ambient temperature sample value from the LSM6DSL sensor, specified as a datetime.

Extended Capabilities

C/C++ Code Generation

Generate C and C++ code using MATLAB® Coder™.

• Timestamp value is always returned in seconds.

• When you create an lsm6dsl sensor object and do not specify the I2C address in the name-value pair, the default I2C address is considered by the LSM6DSL sensor. For the LSM6DSL sensor, the default I2C address is '0x6A'.
