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 haven’t had much experience with the STM32G0 family yet, but my course participants have. Recently, we were solving together a problem with interrupts not working on the STM32G031J6M6 known from the STM32G0316-DISCO board. It was an interesting problem, so I decided to share it more broadly. Handling interrupts via Read more
You’ve surely more than once on the Internet (and not only there) seen problems from people taking their first steps with microcontroller programming. One of such problems is that we can’t “do many things at once”. For example, wait for a measurement while at the same time blinking an LED Read more
In 2019, I asked the community of the STM32 Polska group on Facebook which IDEs or other editors they use to write code for STM32. In 2019 we still didn’t have STM32CubeIDE, so that ranking is already outdated. Time to refresh the stats. I asked programmers again what they use. Read more
If we think about debugging, what comes to mind? Breakpoints, stepping through code, but above all printing. When dealing with microcontrollers, most often we send messages to the serial console terminal on the PC. We use one of the UART interfaces for this. What if we don’t have that UART? Read more
The topic of UART combined with DMA keeps coming back like a boomerang. Especially receiving data on a microcontroller causes the most problems. Why? Because we don’t know how much data will arrive. That’s why receiving via DMA is a somewhat poor idea, because we have to specify in advance the amount of data being received. But not always…

Doing graphics on microcontrollers is always a huge challenge. Even more so if it’s supposed to look nice. For years we’ve known simple so‑called GFX libraries that let us draw bitmaps or various fonts. However, that’s not enough, because often our GUI still looks like it came from 1990s devices, Read more
I’ve just finished producing all the planned materials for my STM32 Course for Beginners (the course content is conducted in Polish). This is the perfect time to summarize what I’ve accomplished so far. I also learned a lot while creating this course. Here’s my little summary.

Many beginners, when they want to introduce some test changes in their project, don’t always use Git. Sometimes there’s also a real need to clone a project in order to develop it completely separately. First thought? Copy-Paste. It’s not a bad solution, but when using CubeIDE we’ll discover that there’s quite a big problem with it.
