Getting started with STM32 MCUs programming
Course Overview
About This Free Course
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.
Who Should Take This Course
"Getting started with STM32 MCUs programming" is aimed at people who want a practical, structured introduction to development without paying full price for it. It's a solid fit if you're starting out in development and want a guided course rather than piecing tutorials together yourself, if you've tried free YouTube content on the topic and want something more organized, or if you already work in a related area and want a refresher you can finish at your own pace. Since enrollment happens on Udemy itself, you keep full access to view the lectures, download any provided resources, and revisit the material later — this isn't a stripped-down or time-limited version of the course.
Why This Course Is Worth Taking
Our take: this listing earns a spot on FreeWebCart because the coupon we verified actually brings the price to $0, not just a token discount, and the course carries a 4.5/5 rating on Udemy. That combination — real reviews plus a working 100% OFF code — is what we look for before publishing a development course. It won't replace hands-on experience or a full degree program, but as a low-risk way to test whether development is worth pursuing further, or to pick up one specific skill, the free price tag makes it an easy yes while the coupon lasts.
