Read one sample of acceleration from sensor



[accelReadings,timestamp] = readAcceleration(imu) returns one sample of the acceleration data on x, y, and z axes read from the sensor in units of m/s2 along with the timestamp. timestamp optional.


Read Acceleration from Sensor

Create an Arduino object and include the I2C library.


Or, you can explicitly specify it in the Libraries Name-Value pair while creating the Arduino object.

clear a;
a = arduino('COM4', 'Uno', 'Libraries', 'I2C');

Create the sensor object.

imu = mpu9250(a);

Return one sample of acceleration data.

accelReadings = readAcceleration(imu)

accelReadings =

   -0.7023    0.1317   10.3968

The acceleration value on x, y, and z axes read from the sensor.

The time at which MATLAB® receives acceleration data from the sensor, specified as a datetime.

Code Generation Using MATLAB Function Block

  • Use readAcceleration in a MATLAB Function block with the Simulink® Support Package for Arduino® Hardware to generate code that can be deployed on Arduino Hardware.

  • Timestamp returned is always in seconds.
