name: zephyr-module description: Creating and integrating out-of-tree Zephyr modules. Covers module.yml configuration, Kconfig and CMake integration within a module, and West manifest inclusion. Trigger when developing reusable libraries, driver packages, or external software components for Zephyr.

Zephyr Modules

Extend the Zephyr RTOS with reusable, out-of-tree modules that integrate seamlessly with the build system.

Core Workflows

1. Defining a Module

Create the directory structure and metadata required for auto-discovery.

•Reference: module_definition.md
•Key Tools: zephyr/module.yml, zephyr/Kconfig, zephyr/CMakeLists.txt.

2. West Manifest Integration

Adding your module to a workspace for distribution and versioning.

•Reference: west_integration.md
•Key Tools: west.yml, west update, west build -t list_modules.

3. Library Wrapping (Glue Code)

Wrapping external C/C++ libraries as Zephyr modules.

•Reference: module_definition.md
•Key Tools: zephyr_library(), zephyr_include_directories().

Quick Start (module.yml)

yaml

build:
  cmake: .
  kconfig: zephyr/Kconfig
