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 Read more
I’m coming today with an interesting topic. It will be a pointer to a function. Unlike “regular” pointers, they are a bit harder. Because functions define more things than just a regular variable. Pointer to a function Pointers can point to any 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 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 In 2019 we still didn’t have STM32CubeIDE, so that ranking is already outdated.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 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 Read more
This post is the beginning of a larger series of articles on my blog. Something that I had my eye on since the first information from ST Microelectronics came into my hands. We’ve got a new series of microcontrollers—and not Read more
Books about the C language describe everything that exists in this language. Literally every smallest detail. Do you need all of it? Of course not! I selected 6 basic elements that, in my opinion, you must learn in order to Read more
You can often come across big banners, slogans, or even course and book titles: “C for AVR”, “C course for STM32”. This can give the impression that the C language is different for each microcontroller. Even more so for a 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 Read more
