## What it is
A collection of C libraries and Keil uVision projects for STM32F4xx series microcontrollers, covering peripherals like USART, SPI, I2C, ADC, DAC, LCD, and touch drivers. It is accompanied by beginner-friendly tutorials on the stm32f4-discovery.net website.

## Use cases
- drive peripherals like USART, SPI, and I2C on an STM32F4 Discovery board
- blink LEDs and read buttons on STM32F429 Discovery
- read temperature from a DS18B20 sensor over OneWire
- drive an ILI9341 LCD with touch input on STM32F429
- learn STM32 microcontroller development as a beginner
- work with SDRAM on the STM32F429 Discovery board

## When to choose
- you are using an STM32F4xx Discovery or Nucleo board and want ready-made peripheral drivers
- you are a beginner looking for tutorials alongside working example projects
- you develop with Keil uVision or GCC (Coocox) for STM32F4 devices

## When to avoid
- you use STM32 families other than F4/F7/F0
- you prefer modern HAL/CubeMX-based or CMake-based workflows exclusively
- you need a license-cleared codebase for commercial products (no license is specified)

## Facets
- artifact type: library
- maturity: maintenance
- function: embedded, sdk, developer-tools
- domain: embedded-systems, hardware, developer-tools, tutorials
- platform: embedded, c, cpp
- tags: stm32, stm32f4, microcontroller, keil, discovery-board, peripheral-drivers, arm-cortex-m
