Zephyr sample for working with KConfig and CMakeLists with nested files and custom Kconfig configurations.

Zephyr sample for working with KConfig and CMakeLists

This repository contains a dummy example of Zephyr RTOS platform to simply showcase how KConfig and CMakeLists files can be used for building the codebase existing in nested files. KConfig and CMakeLists help integrating configuration options both for the build process and the application's utilization.

You can check out the following Zephyr application template that I made where this structure is utilized as well as some other useful techniques.

Implemented Personal Approach On Involving Subfolders/Submodules Into The Project

Dummy module file given inside the nested file (at app/example_module) self configures itself in the build process when some other upper level Kconfig and CMakeLists point to the module file to use its own Kconfig and CMakeLists files. This approach is taken beacuse it feels more intuitive that each module/submodule/driver/library etc. takes care of itself after its folder is decided to be included in the codebase in some other configuration file that's upper level on the folder tree (hierarchical) structure.

Building and running

• nRF Connect SDK is used when building and is application is run with nRF52840DK board. SDK and Toolchain version used: 2.6.0
• Should be able to be built without nRF Connect SDK and with Zephyr only. Other supported boards can be used, too. Further explanation in repository given in References section can be used for further detail.
