STM32 HAL Example Projects – Controllerstech

Welcome to the STM32-HAL repository!
This repository contains hands-on STM32 example projects, covering HAL drivers, peripherals, FreeRTOS, Ethernet, IoT, Modbus TCP, and more.
All projects are designed for beginners and professionals to learn embedded development efficiently.

Most STM32 examples are tested on F1, F4, H7 series boards.
