## Overview

This repository is an embedded-controls teaching resource, not a single application: its principal learner workflow moves from MCU peripherals toward motor and robot-control topics, combining theory with practical work. The supplied tree exposes a GPIO CubeMX project and CMSIS material, while the README documents broader tutorial branches whose source paths are not present here; those branches are shown as documented capabilities, not inferred implementations. The GPIO runtime nodes reflect filenames only; source excerpts do not establish their call wiring.
