Select a System Object Template
System objects are used to define the behavior of device driver blocks. Follow these steps to create your own System object™ by modifying the template System object.
- In the MATLAB® Editor, open the template system object class file, - Sink.m.
- Save a copy of the class file and rename it - DigitalWrite.m.
- Open - DigitalWrite.mand change the class name to- DigitalWrite.- classdef DigitalWrite < matlab.System ... & coder.ExternalDependency ... end 
- Change the name of the constructor method to - DigitalWrite.- methods % Constructor function obj = DigitalWrite(varargin) % Support name-value pair arguments when constructing the object. setProperties(obj,nargin,varargin{:}); end end - Note - A MATLAB class requires the class name, constructor, and file to be identical. 
- Save the changes to - DigitalWrite.m.
In the next section, you will Specify the Initialization, Output, and Termination Behavior of the System object.
