Thanks to this, you have easy access to various types of expansion boards with sensors or controllers.ĭiscovery 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. I’m gonna focus on the only right choice in my opinion: STM32CubeIDE. IDE stands for Integrated Development Environment. 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. #Stm32 nucleo f401re schematic professional# It is based on the popular Eclipse, so its capabilities can be extended even more with external plugins. What do I mean by that? An approach to writing code itself. In the sense of whether and which libraries you want to use. 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. 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 of “pure C”. These libraries are very oriented towards a specific uC model, so it makes migration a bit more difficult. These are high-level libraries also integrated with STM32CubeIDE. I think this is the best option (especially if you are just starting). This is what I’m gonna cover in this article.Īdmittedly, the LL has more options, but I’m sure that you’ll not even come close to the limitations of HAL.Īnd now, the best part: HAL libraries can coexist with LL libraries! If you want a particular periphery to use LL instead of HAL, you just change the setting in STM32CubeIDE. Let’s deal with the main topic of this article! How to program STM32? Okay, the boring introduction is fortunately behind us. in Target Selection Tool, select the appropriate microcontroller or Evaluation Board.in Device Configuration Tool initialize all the necessary peripherals.program STM32 by clicking the debug button.In a nutshell, this is what it looks like. To make it even more interesting, we’re gonna program a Nucleo board to turn on the LED every time the button is pressed. Download and installation of STM32CubeIDE Such a “Hello World” in the world of microcontrollers □ STEP 0. Installation is simple and requires no detailed description. However, to make this article as complete as possible, I couldn’t skip this step.ĭownload the latest version of STM32CubeIDE directly from the ST website – LINK. There are versions for macOS, Windows, and Linux. To be able to download you need an account there. You can register it when downloading the installation file.ĭuring installation, you can leave all the settings at default, it will be ok. The first window you will see right after running the program will be the STM32CubeIDE Launcher. Choose a location where the IDE is to save and create new projects. You can set any folder, I’m gonna leave the default path. When you are ready generate the code of your pre-project. Don’t worry, you’ll be able to do this as many times as you want while developing your project. The IDE will ask whether to save the project if you haven’t done it yourself. This is how you generated your project template. #Stm32 nucleo f401re schematic download#.#Stm32 nucleo f401re schematic professional#.#Stm32 nucleo f401re schematic software#.
