Code Generation Using MATLAB Function Block

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

  • Configure the Arduino peripherals to the appropriate mode using configurePin before using writeDigitalPin in the MATLAB Function block.
