Introduction to Zephyr Part 3: Kconfig Tutorial

This 54-minute tutorial video explores the Kconfig configuration system in the Zephyr RTOS, teaching how to use menuconfig to customize embedded applications without hardcoding options. Learn to create a random number generator application while resolving build errors related to missing Kconfig symbols. Discover how to navigate the text-based menuconfig interface, search for configuration options, and enable features needed for your project. Master the management of multiple configuration files by separating general app settings from board-specific overrides, making your code more portable across different hardware. The tutorial also covers creating custom Kconfig symbols in separate modules for conditional compilation, allowing you to add or remove features at build time. By the end, gain confidence in using Zephyr's configuration system to streamline development workflows and reduce complexity in embedded projects. Supplementary materials include a written version of the tutorial, GitHub repository with challenge solutions, and links to official Zephyr documentation.
