System Configuration Tool (SysConfig) is a graphical interface for configuring your project. Configuration files, C source files and header files are generated based on the parameters configured in the SysConfig dashboard.
SysConfig should be used as a standalone tool for script-based builds (such as for Matter).
The document will help for getting started in tailoring the syscfg file to your application needs.
You can find the standalone SysConfig tool on the SysConfig Standalone Installer Download Page.
The location of the Matter syscfg file is located here: /examples/<name>/cc13x4_26x4/chip.syscfg For example, on the github web: https://github.com/project-chip/connectedhomeip/blob/master/examples/lock-app/cc13x4_26x4/chip.syscfg The local file in your cloned repository should be used.
This file is used by Matter build scripts, when it invokes SysConfig CLI. In order to edit the file for your custom application configurations, you'll need to open the file with the SysConfig GUI. Before doing so, you should add the following line above the /* Modules */ comment:
// @cliArgs --product <path to SDK>/.metadata/product.json --board /ti/boards/LP_EM_CC1354P10_6 --rtos freertos
As an example, after adding the necessary <path to SDK>, it would look like:
// @cliArgs --product /home/Documents/repos/connectedhomeip/third_party/ti_simplelink_sdk/repo_cc13xx_cc26xx/.metadata/product.json --board /ti/boards/LP_EM_CC1354P10_6 --rtos freertos
If the file is not found, then you may need to first initialize the submodules:
git submodule update --init
Now you can open the file in SysConfig GUI. Once you are done, remove the @cliArgs line then save the file. Now the Matter build scripts will use the updated .syscfg file.
To preview the code to be generated reference the Generated Files image, the button at the top of the Configuration pane you will find a list of Generated Files. After selecting a file you will be able, in real-time, to identify how the changes in the GUI affect the generated files. This will help you review the relationship between the GUI and the code.
Whenever you re-build the project, SysConfig will re-generate the files. Because of this, any changes made directly in the generated files will be overwritten.
