What is STM32? STM32 is a family of 32-bit microcontrollers based on the ARM Cortex-M core and developed by ST Microelectronics. Thanks to the wide range of models, it’s very easy to find the right model for your applications. ST provides an application: ST MCUFinder, which, on the basis of a number of filters, will automatically search for the model/models that meet all the requirements. Depending on the version, they have a low power consumption and quite limited resources, or a very high speed and a lot of peripherals. What do I need to program the STM32? 1. Documentation Before you really use a specific microcontroller in your project, you should at least glance at the datasheet. You should check what peripherals it offers, how many GPIOs it has, and whether the clock is sufficient for your requirements. But relax, you don’t need to read the whole thing, at least not right away 🙂 Below, I’m gonna present you several variants of the paths you can follow to develop a project on STM32. Sometimes you need to know the documentation very well, and sometimes you just need to know where it is to look at it when is need it. 2. Language I mean programming languages, of course. The only correct option here is C. Don’t bother with other creations. The time will come for that once you get the C language. 3. Hardware For starters, I recommend any Nucleo or Discovery, evaluation board. There’s an ST-LINK programmer integrated into it, so you don’t need to buy an external one. Additionally, you can use it later to program other STM32 microcontrollers. Nucleo boards have an Arduino-compatible connector. So if you have any shield for the Arduino UNO board, you can use it with Nucleo. Thanks to this, you have easy access to various types of expansion boards with sensors or controllers. Discovery boards, on the other hand, very often it has some sensors built into the board. You can also start your adventure without buying any external boards. You can also choose the recently popular STM32 BluePill. It has a nice, small size, however, it doesn’t have a built-in programmer, so you have to buy it separately. Any STLink V2 clone (like this) will be ok. It cost pennies and you will surely find it locally. 4. Software ST Microelectronics actively supports developers. That’s why they made available a wide portfolio of free software. I’m not gonna dwell on all the options such as (paid) IAR Embedded Workbench, (paid / free) µVision – Keil, or free SW4STM32 – System Workbench or Eclipse with plugins. I’m gonna focus on the only right choice in my opinion: STM32CubeIDE. IDE stands for Integrated Development Environment. What is STM32CubeIDE? STM32CubeIDE is an all-in-one development software ecosystem. It has integrated: a microcontroller selector, peripheral configurator, code generator, compiler, debugger, and programmer. Moreover, it is completely free for both hobby and professional purposes. It is based on the popular Eclipse, so its capabilities can be extended even more with external plugins. However, I didn’t need to do that yet. 5. Framework What do I mean by that? An approach to writing code itself. In the sense of whether and which libraries you want to use. You can choose from: – Pure C language If you want your code to be optimized as much as possible, take up a minimum amount of memory, and be super fast this option is for you. However, it’s by far the most difficult path. In this case, you’re working directly on the registers, so Datasheet, Erratum to Datasheet, Application Notes, and Reference Notes you have to get to know cover to cover. If you are just starting, I strongly advise against this approach. – Arduino You’ve probably heard and maybe even used Arduino before. True, it makes it much easier to get started, however it uses a simplified version of the C / C++ language. So learning it won’t let you migrate later on to another IDE, or even to another family of microcontrollers. Arduino is very limited when it comes to STM32. Only supports a few boards, e.g. BluePill. Additionally, a lot of libraries are made by the community, so the quality of them really varies. Believe me, I’ve seen some really poor written libraries. This is why I’m not a big fan of Arduino. -mBed The online environment was created for ARM microcontrollers. Such an Arduino for STM32 🙂 But you are writing in classic C / C++, which is a big advantage. Over the last few years, it has grown quite strongly both in terms of libraries and community. However, I find this environment quite clunky and uncomfortable to use. Although I’ve only used it a few times, I definitely don’t want to go back to it. – (LL) Low Layers libraries Low-level libraries integrated with STM32CubeIDE. If you have a limited amount of available memory and your code needs to be well optimized this is the option for you. It requires you to have a fairly good knowledge of documentation and registers. Fortunately, not as much as in the case
