Reset Count Value to Zero

This example uses:

MATLAB Support Package for Arduino Hardware MATLAB Support Package for Arduino Hardware

Open Live Script

Create a connection to the Nano Motor Carrier.

arduinoObj = arduino('/dev/ttyACM0','Nano33IoT','Libraries','MotorCarrier');
mcObj = motorCarrier(arduinoObj);

Create a connection to the rotary encoder.

encoder = rotaryEncoder(mcObj,1);

Reset encoder count value to 0.

resetCount(encoder);

Set Count Value Encoder to Specific Value

This example uses:

MATLAB Support Package for Arduino Hardware MATLAB Support Package for Arduino Hardware

Open Live Script

Create a connection to the Nano Motor Carrier.

arduinoObj = arduino('/dev/ttyACM0','Nano33IoT','Libraries','MotorCarrier');
mcObj = motorCarrier(arduinoObj);

Create a connection to the rotary encoder.

encoder = rotaryEncoder(mcObj,1);

Reset encoder count value to 10.

resetCount(encoder,10);
