Getting started with STM32 MCUs programming

STM32 microcontrollers are among the most widely used in many domains: consumer electronics, automotive, medical devices and Internet of Things (IoT). They are powerful microcontrollers thanks to their architecture based on ARM Cortex-M cores, with very low power consumption.

This course will guide you step-by-step in mastering STM32 MCUs, by taking advantage of the STM32Cube ecosystem, a collection of tools and software libraries provided free of charge by ST Microelectronics. This course will enable you to quickly become autonomous for your own projects.

Through practical projects on a Nucleo board (affordable STM32 development board manufactured by ST, compatible with Arduino shields), you will learn how to configure and use the main peripherals and communication interfaces of the STM32: UART (serial port), I2C, SPI, timers, DMA. For this, we'll use STM32CubeMX, a powerful tool provided by ST allows to graphically configure the hardware, and generate initialization code. We will also use the ST HAL (Hardware Abstraction Layer) library, which makes the development much easier and faster.

This course follows the new workflow introduced by STM32CubeIDE v2 end of 2025, in which STM32CubeMX is no longer integrated, but has to be used as a standalone tool.

Theoretical lessons explain various concepts that we will meet throughout the course: architecture of the STM32, interrupts, communication buses, peripherals, and so on.

This course is intended for engineers, students and hobbyists, with or without experience of microcontrollers. Basics in C language are required, as we will use this language.
