About stm32_samples

stm32_samples is an open-source collection of sample code for various STM32 microcontrollers, maintained by dwelch67 on GitHub. It includes bootstrapping examples, peripheral initialization, and basic firmware for a wide range of STM32 development boards, such as Nucleo, Discovery, and custom PCBs like the Black Pill. The code is written primarily in C, with Makefile build support and some Assembly and Ada components. The repository serves as a practical reference for embedded developers learning or working with STM32 processors.

Key Features

Covers multiple STM32 families: F0, F1, F2, F4, F7, G0, G7, L0, L1, etc.
Supports popular boards: Nucleo, Discovery, Black Pill, and custom PCBs
Examples include boot code, GPIO, UART, and other peripherals
Build system using Makefile and GNU toolchain
Contains both C and Assembly source code
Some Ada examples for select targets

Pros & Cons

Pros
  • Open source and freely available on GitHub
  • Broad hardware support across many STM32 variants
  • Uses standard toolchains (GCC, Make) making it easy to build
  • Includes low-level assembly examples for understanding MCU internals
Cons
  • No official documentation or user guide provided in the repository
  • Repository appears to be a personal collection with minimal maintenance
  • Examples may lack explanation or comments for beginners
  • No releases or versioned packages; code is used directly from master branch
