flync_4_app¶

The app layer describes applications of a system in a top-level apps directory. Applications are then bind inside an ECU Controller in an optional app_bindings file.

Applications¶

Each file in the top-level apps directory defines one set that maps onto transport services. The set name is implied from the filename on disk.
