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
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
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 In 2019 we still didn’t have STM32CubeIDE, so that ranking is already outdated.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
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…

For some time now I’ve been observing what’s happening among beginner embedded programmers. Actually, not only among them, but also in what embedded programming learning materials are passing on to future juniors. I have some serious reservations.

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.
