How fh-stece2023-org/fh-stece2023 works

This repository implements a GPIO-controlled door system: inputs and analog sensing inform a door state machine, which selects motor behavior. The tree and excerpts also show hardware and mock implementations, event-loop utilities, and I2C sensor support. The main executable’s wiring was not shown, so links from it to runtime components are left unverified; unsampled subsystems are included only where their paths and roles are supported by the tree or README.

Main entry points: analog-sensor.h Analog sensor interface · motor.h Motor interface · door.cpp Door state machine · run-door.cpp Door executable
