ESP32 - Kconfig with ESP-IDF Tutorial

Description:

In this video, I’ll show you how to use Kconfig with ESP-IDF to make your ESP32 projects configurable and easier to maintain. Kconfig is the system behind the familiar idf.py menuconfig tool, allowing you to enable or disable features, set parameters, and even create your own configuration options without manually editing source files. We’ll start by creating a simple ESP-IDF project and adding a custom component with a Kconfig file. You’ll learn how to define new configuration symbols, expose them in menuconfig, and use them in your code with conditional compilation. Along the way, I’ll demonstrate how ESP-IDF translates your menu selections into CONFIG_* macros and integrates them into the build system.

Instead of hardcoding values or editing multiple build files, you’ll be able to quickly adapt your firmware for different use cases, hardware revisions, or debugging scenarios.
