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?

In the previous post I started a mini-series dedicated to the built-in RTC in STM32 chips. I began with probably the most popular microcontroller SMT32F103 found among others in the cheap BluePill board. I got to the point where after resetting the microcontroller the time was still correct, but the date started from zero.

STM32 microcontrollers undoubtedly have many killer features. Of course, compared to the ancient AVRs that are still used in the most popular Arduino Uno. One of those things is that STMs have a built-in real-time clock, RTC for short. Let me show you in detail what working with such a clock looks like using the HAL library generated by CubeMX.

In the last article I described the adventures related to the original API provided for the laser distance sensor VL53L0X. I got to the point where I managed to run a single measurement. However, I’d like to relieve the microcontroller a bit so it doesn’t have to wait so long for the measurement to finish. The sensor has an interrupt output pin, so why not use it?

Anyone who has spent even a moment dealing with robotics knows that distance measurement plays an incredibly important role in this field. Practically everywhere we deal with devices that move, some kind of obstacle detection is advisable. This is often implemented by measuring distance.

Not long ago I wrote an article about how to implement UART reception via DMA. I successfully wrote such a “hands-free” implementation for STM32F411. Many of my readers also use cheap boards with F103 and porting the library caused huge problems. I adapted my code and I will show you what the differences were and the potential difficulties.

It’s been a while since I put together the list of eight best IDEs for STM32. At the time of writing that article, no one publicly knew what was about to happen. ST acquired Atollic, taking over their STM32 IDE, TrueStudio. As a result of these events we finally have something “made” by ST, namely STM32CubeIDE. So let’s see what they have to offer.

Lately, lots of people have been asking me to port my code to STM32F103C8T6. I’m reluctant to take on this task because HAL is fairly easy to port. Besides, I’d like to teach programming, not copying code 🙂 There are also a few other issues I have an internal problem with when it comes to this popular board from China.
