ESP IDF App with component and Kconfig

component

Three ways to use a component:

• Add it in esp/esp-idf/components - but this is not be done.
• create a directory name components in the top-level of the project
• add path to the component in CMakeLists.txt using EXTRA_COMPONENT_DIRS

Kconfig

• Kconfig file always needs to be in a component
• Each component can also have a Kconfig file, alongside CMakeLists.txt. This contains configuration settings to add to the configuration menu for this component.

Two ways to use Kconfig:

• in a component at top level
• if used in a project it must be inside myproject/main as we know main is a special component and Kconfig can only be defined in a component
