RTC Builder

Open RTC Builder.
You can find your "MyFirstRTC" project in your workspace.

Open RTC.xml

Your input options are saved in RTC.xml.
Double click and open "RTC Builder view", and Select "Data Port" tab.

Add DataOutPort

Add DataOutPort and change "Port Name". Port name is not a variable's name. It's used as an interfaces name usually displayed in RT System Editor.

You can select "Data Type" of your DataOutPort by selecting the drop-down list.
* If you had no selection items in the Data Type list, your environmental variable RTM_ROOT Is not set. Please check here.

Please edit "Var name" of your DataOutPort. This name is used as a variable name in your cpp code.

Generate Code

Generate Code in Basic tab.

RTC Builder supports incremental development.
Your code and generated code in your project can be merged with the following dialog.

Select merge button.

Edit code

Your project may not need to use cmake. Open your cpp code and edit "onExecute" code.

RTC::ReturnCode_t MyFirstRTC::onExecute(RTC::UniqueId ec_id)
{
  std::cout 

m_v_out is a data buffer for the data port "out". The "v_out" is defined in RTC builder as "Var Name".

And you can see "m_v_outOut" that is the Variable name of DataOutPort. The "write" member function means "Output data from data buffer."
