esp-idf-setup

ESP-IDF setup installs the development framework, configures shell aliases, and prepares your environment for ESP32 projects. Start by installing ESP-IDF matching your target version, configure the shell alias for easy access, then create your first project and run the build to verify the installation works.

Yes, monorepo integration is supported through root CMakeLists.txt configuration and idf_component.yml dependency management. Add projects to a shared root with proper component wiring so multiple ESP32 projects share build configuration and dependencies while remaining independent.

Menuconfig is the configuration interface and sdkconfig is the generated configuration file that stores ESP32 build settings like chip model, peripherals, and optimization flags. Use menuconfig to customize project behavior; sdkconfig.defaults sets defaults applied across the monorepo.

Configure CMakeLists.txt to declare component dependencies and build rules, then manage local and IDF components through idf_component.yml. This wiring ensures the build system resolves all dependencies and links components correctly for your ESP32 project.

No, one ESP-IDF installation supports multiple projects. Create new projects using templates or manual scaffolding, add them to the monorepo, and configure each project's CMakeLists.txt and component dependencies independently without reinstalling the framework.
