Read one sample of acceleration from sensor
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] = readAcceleration(
Timestamp is optional.
readAcceleration function is available for the
Read Acceleration from Sensor
Create an Arduino object and include the I2C library.
a = arduino();
Or, you can explicitly specify it in the
pair while creating the Arduino object.
clear a; a = arduino('COM4', 'Uno', 'Libraries', 'I2C');
Create the sensor object for the sensor in use.
The sample code and output in this example is for
object. If you are using another sensor that supports
readAcceleration function, use the corresponding
sensorobj = mpu9250(a);
Return one sample of acceleration data.
accelReadings = readAcceleration(sensorobj) accelReadings = -0.7023 0.1317 10.3968
sensorobj — sensor object
The sensor object.
accelReadings — Value read from the sensor
The acceleration value on x, y, and z axes read from the sensor.
timestamp — Timestamp
The time at which MATLAB® receives acceleration data from the sensor, specified as a datetime.
Code Generation Using MATLAB Function Block
readAccelerationin 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.
