Set Output Port Properties

Step 6 of 8 in Create Custom Device Driver Block for Arduino Library

The colorSensor.m reference System object™ contains a common default implementation of the methods that defines the output port properties for the block. Update the properties as follows.

methods (Access = protected)
    %% Define output properties
    function num = getNumInputsImpl(~)
    num = 0;
    end

    function num = getNumOutputsImpl(~)
    num = 3;
    end

    function varargout = isOutputFixedSizeImpl(~,~)
    varargout{1} = true;
    varargout{2} = true;
    varargout{3} = true;
    end

    function varargout = isOutputComplexImpl(~)
    varargout{1} = false;
    varargout{2} = false;
    varargout{3} = false;
    end

    function varargout = getOutputSizeImpl(~)
    varargout{1} = [1,1];
    varargout{2} = [1,1];
    varargout{3} = [1,1];
    end

    function varargout = getOutputDataTypeImpl(~)
    varargout{1} = 'double';
    varargout{2} = 'double';
    varargout{3} = 'double';
    end

    function icon = getIconImpl(~)
    % Define a string as the icon for the System block in Simulink.
    icon = 'Color Picker';
    end
end
