The Pinmap configurator is an intuitive end user graphical assistant dedicated to configure the pinmap of Stellar products.

The configuration is done using a textual edition of the peripherals. For each peripheral, you need to set the associated registers.

An application's pins configuration is based on a board on which the application is supposed to be executed. There is a need to describe the pinmap configuration for this board before being able to add pin configurations dedicated to the application itself.

There are some predefined boards (included inside StellarStudio) that you can start from. Whenever a predefined board needs some modifications, you can import this board into your project's workspace. You can even start from scratch, creating a new board predefined pin configuration from a blank board.

When a configuration is created, the tool looks like in the above picture, where three main areas are present.


  1. Project tree: contains the various projects of the workspace and their corresponding files.
  2. The outline will show the hierarchical structure of the gpio file shown in the editor area.
  3. Editor area: contains the editing part of the tool, where configurations are manipulated, and where generated C, xls and html files can be seen.
