Using Simplicity Studio’s Pintool and Project Configuration with Matter

At some point during product development you may need to move your project over to your custom hardware. In this case, you will likely need to change the pinout and hardware configuration in the example project to reflect your own custom project. You can do this with Simplicity Studio’s Pintool starting from a blank C++ project.

1. Locate the board support files in the Matter repo

The pin and peripheral configuration for your example application is stored within the Silicon Labs Matter support directory. For all the examples used in the matter repository, the peripheral and pin configurations are stored at

./third_party/silabs/matter_support/matter/efr32/<chip_family>/<board>/config

When creating a configuration for a custom board do the following:

  1. Create a Custom C++ project within Simplicity Studio.

  2. Include your desired peripherals in the project.

  3. Copy the generated output config files into a custom board support directory within the Matter repository.

2. Create a sample “Empty C++ project” in Simplicity Studio

  1. In Simplicity Studio click Create a New Project to start the project wizard. Choose your development board type, and the latest Gecko SDK you’ll be working from. Click Next.

  2. Select the Empty C++ Project example and click Next.

  3. Click Finish to create your project.

3. Customize your Components and Pin configuration in Simplicity Studio

Once you have your project created you will see your project and project configuration in Simplicity Studio’s Project Configurator. Full documentation on the use of the Project Configurator and Pin Tool are located here: Simplicity Studio 5 User’s Guide

4. Generate your Component and Pin configuration in Simplicity Studio

When you save your project configuration, Simplicity Studio saves all the generated header files out into a config directory in your project. These are the files that make up the software component and pin tool configuration for your device.

5. Move your pin configuration over to your Matter project

All of the header files in your config project directory constitute the hardware configuration for your device. Copy these files into your Matter project so that they can be used in place of the ones provided in the example.
