## Overview

This repository is a collection of independent MCU product projects, not one application with a shared runtime. Its principal workflow is therefore per-project: firmware interacts with a device-specific interface and produces a device action or user-facing function. The tree identifies examples including a soldering iron, clock, and charging equipment. The sampled H7-TOOL sources document USB mass-storage callbacks backed by eMMC and DAPLink virtual-filesystem transfer handling; other project internals were not sampled, so their wiring is intentionally not inferred.
