The Properties editor is provided for use with ARM assembler and C/C++ files. It enables you to configure your source code to provide GUI components for changing specific values without editing the code directly. Control tags can be embedded in commented blocks within your source code and then initialized to enable a GUI environment for setting up and modifying variables or #defines, for example, hardware initialization. Updates are synchronized so you can make changes in the source code or the GUI components.

If this is not the default editor, right-click on your source file in the Project Explorer view and select Open With → Properties Editor from the context menu.
