In mid-July 2025, together with several leading creators from the embedded industry, we had the opportunity to visit the STMicroelectronics factory in Agrate, Italy. How did it happen? …well, I know 😅 This visit had been planned many months earlier as part of cooperation with Polish ST ambassadors. It was Read more
UART Communication on STM32. Transmission to PC | STM32 on Registers #6 We have already learned the basic operations on GPIO, as well as ways to delay individual tasks. Today we will go beyond the microcontroller. We will communicate with our computer via the UART interface. In this post we Read more
Doing 3 Things at Once, or How to Implement a Software Timer? | STM32 on Registers #5 Let’s get to know one of the effective ways not to block the processor’s work by waiting. It will be a Software Timer. This is an absolute foundation for an embedded programmer. A Read more
Reading a Button on STM32 | STM32 on Registers #4 A button is one of the simplest communication interfaces between a microcontroller and a human. It’s an input interface, so it takes information from us. How to read a button on STM32? That’s exactly what I’ll show you today. Of Read more
My NEW course: STM32 on Registers Straight to the point: the long-awaited course on programming STM32 on registers is finally coming! Oh, how often many of my readers and course participants themselves have asked about it 😅 After months of work, I’m ready to announce its launch. When? The first Read more
Summary of 2023, Plans for 2024 Ever since I started operating on the Internet, I haven’t written a year recap even once. So I’m starting a recurring post summarizing what has been happening with me over the last year. I’m starting with the year that has just ended: 2023. The Read more
Delay Using the SysTick Timer on STM32 Blinking an LED from the previous article had one big drawback. In reality, we didn’t fully control the time between changing states on the GPIO pin. Such a silly for loop doesn’t have a defined execution time. Of course, you could check what Read more
Blinking an LED on STM32, GPIO Output Recently, we learned how to set up an STM32 project for register-level programming. This time I’ll show you how to blink an LED 😎 In today’s post we’ll go through configuring GPIO Output and learn how to control the output of a single Read more
How to create an STM32 project for register-level programming? For a very long time, readers and course participants have been asking me: “MATI! When will you finally do something on STM32, but at the register level?”. I usually replied: “when the time comes”, but I didn’t know myself when that Read more
I’d like to make an introduction to splitting a project into files in the C language. We also need this in order to understand what a module or a compilation unit is. A good understanding of the concept of a “compilation unit” will make it so that later you’ll be Read more
