Embedded Development

What modern C++ can and cannot do in resource-constrained embedded systems—from zero-overhead abstractions and memory management to peripheral programming, interrupt concurrency, and finally STM32 practice and RTOS.

STM32F1 Hands-on Series

This is a complete roadmap for writing STM32 code in modern C++ from scratch. It follows the sequence "Environment → LED → Button → UART", refactoring each peripheral from C all the way to C++23:

• Development Environment Setup — Toolchain, project structure, CMake, WSL2 USB passthrough, GDB debugging.
• LED Blinking: Evolution from C to C++ — From HAL registers to templates and constexpr.
• Button Input: Debouncing, State Machines, and Type Safety — From polling to interrupts and state machines.
• UART Serial Communication — From protocols to interrupt-driven, std::expected error handling.

Embedded Special Topics

These are special topic articles migrated from an older tutorial, covering zero-overhead abstractions, memory management, register access, and interrupt safety. They serve as supplementary reading for the hands-on series:
