project-layout

A standard Python and C++ extension project layout uses canonical src/, tests/, docs/, and environment directories alongside specific root files. This structure separates compiled extension source code from Python modules and test suites for maintainable hybrid development.

Structure a PlatformIO firmware project by applying the C++ PlatformIO firmware archetype, which defines canonical root files, environment directories, test structures, and source code organization specifically tailored for embedded firmware development and deployment.

Yes, the project structure convention supports C# Unity projects as one of five archetypes. It provides a canonical directory layout detailing root files, documentation placement, and source code organization specific to Unity development workflows.

The best way to organize tests and documentation in a Python-only project is following the Python-only archetype convention, which enforces specific test directory structures and documentation placement patterns to ensure project navigability and team-wide consistency.

You need the C++ PlatformIO library directory layout when developing reusable embedded libraries rather than firmware, applying its specific root files, environment directories, and source code organization to ensure library portability and convention adherence.
