Configure Zephyr: Kconfigs and Devicetree in Simple Words
summary
Claims that Kconfigs and Devicetree are simple and shows concrete workflows: use menuconfig / guiconfig to set options, save a fragment in project.conf or set CMake EXTRA_CONF_FILE, and the build-time merge produces autoconf.h and devicetree-generated.h used by C code. Demonstrates device tree syntax, node labels, DT_PROP macros, and binding YAMLs. Shows a Tracealyzer-enabled fragment as an example and the minimal config shrinks 1,167 lines to ~10, making persistent, shareable configuration practical.
