target.MainFunction Class

Namespace: target

Provide C and C++ dependencies for main function of target hardware application

Description

Use the target.MainFunction class to provide main function dependencies for an application main function that runs on your target hardware. For example, C and C++ initialization and termination code, include preprocessor directives, and specification of main function arguments for the application.

To create a target.MainFunction object, use the target.create function.

Create a target.MainFunction object and associate it with a target.Board object, which captures the main function dependencies for an Arduino® board. Workflows, such as processor-in-the-loop (PIL), can use this information when generating a main function for an application that runs on the target hardware.

board = target.create('Board', 'Name', 'Arduino Board')
mainFunction = target.create('MainFunction');
mainFunction.Name = 'Arduino Main Dependencies';

mainFunction.IncludeFiles = { 'Arduino.h' };
mainFunction.InitializationCode = fileread('arduino_main_initialization.c');

board.MainFunctions = mainFunction;

In the code snippet, arduino_main_initialization.c contains C code. For example:

/* Initialize system */
init();

This code snippet from Set Up PIL Connectivity by Using Target Framework (Embedded Coder) shows how you can create and use a target.MainFunction object to specify main function arguments that are required for an API implementation.

comms = target.create('CommunicationInterface');
comms.Name = 'Linux TCP Interface';
comms.Channel = 'TCPChannel';
comms.APIImplementations = target.create('APIImplementation', ...
                                         'Name', 'x86 rtiostream Implementation');
comms.APIImplementations.API = target.create('API', 'Name', 'rtiostream');
comms.APIImplementations.BuildDependencies = target.create('BuildDependencies');
comms.APIImplementations.BuildDependencies.SourceFiles = ...
                                                        {fullfile('$(MATLABROOT)', ...
                                                        'toolbox', ...

comms.APIImplementations.MainFunction = target.create('MainFunction', ...
                                                      'Name', 'TCP RtIOStream Main');
comms.APIImplementations.MainFunction.Arguments = {'-blocking', '1', '-port', '0'};
hostTarget.CommunicationInterfaces = comms;
