## Overview
This repository is a personal STM32 and embedded-systems learning log, not a runtime application. Its workflow is a learner progressing from fundamentals toward peripherals, processor internals, and interrupts through explanatory notes and practical experiments. The graph represents the documented learning stages and the notes present in the tree; the README also names future or broader topics that have no dedicated files yet. No source excerpts were provided, so relationships are limited to the README’s stated progression and scope.
