readAcceleration

Read one acceleration data sample from LSM6DSL sensor

Description

example

[accelReadings,timestamp] = readAcceleration(sensor) returns one sample of the acceleration data from the LSM6DSL IMU sensor. The acceleration sample is returned as a 3-by-1 vector in m/s2 along the X, Y, and Z axes. The function also returns the timestamp at which MATLAB® receives the acceleration data from the LSM6DSL sensor. The timestamp output is optional.

Read the acceleration data from the LSM6DSL IMU sensor on the X, Y, and Z axes.

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+'

    AvailableDigitalPins: [4,5,6,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27]
    AvailableSPIChannels: {‘CE0’,’CE1’}

        AvailabelWebCams: mmal service 16.1 (platform:bcm2835-v4l2)

Create an lsm6dsl sensor object on the I2C bus 'i2c-1' on address '0x6B'.

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

  lsm6dsl with properties:

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

Return one sample of acceleration data read from the LSM6DSL sensor on the X, Y, and Z axes.

[accelReadings,timestamp] = readAcceleration(sensor);
accelReadings =

  data

    -3.0632   -3.6129   -8.4065


timestamp = 

  datetime

   15-Jan-2021 11:35:54.728

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

[accelReadings] = readAcceleration(sensor);
accelReadings =

  data

    -3.0632   -3.6129   -8.4065

Input Arguments
