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.

In the previous post in the dual-core series, I showed you a really strong contender, namely the STM32H745, which is on the Nucleo 144-size board. I got to the point where I created the first project. We already have the project structure behind us. So how do we run our code now?

Everyone starts with something at some point. Since you’re here you’d probably like to start your adventure with STM32 microcontrollers. I also once wanted to. Nowadays, we look for our first help on the Internet. That’s why this blog post was created. (more…)
If you asked men about this in general, probably each of them would say yes. The problem is that while answering, they’re probably not thinking about microcontrollers… So let’s consider our microcontrollers. Is it good to have two cores, or rather – two CPU cores?

I ended the last post about the SSD1327 OLED with the note that in order to use the GFX library, you need to introduce a few modifications to it. Today I’ll deal with those modifications and we’ll have full functionality of our display with a 16-level grayscale. At the end, we’ll check what speeds can be achieved on such an I²C OLED.

When working with various graphic displays, you will almost certainly reach a moment when you need some graphics to display. After all, that’s why we pick such a display—to show some icons or other bitmaps on it. Alright, but can we just drop a BMP or JPEG file into our microcontroller? Well, no! So how do we deal with such graphics? What should we use? I’ll show you right away 🙂

Recently I did a bit of theorizing about an OLED with a 16-level grayscale. We already know how those 16 colors are obtained and how the display’s RAM memory is organized. Time to display something on it, right? First, we’ll try using a graphics library from a regular monochrome OLED, which I used for the SSD1306. Let’s get to it!

Recently on my social media I pointed out that for quite a long time no article about displays had appeared. In a poll I proposed two models that I have on hand and the winner was an OLED with a controller that enables a 16-step grayscale. Today I’ll start the topic from the theoretical side, maybe even in a light column-like form 🙂
