![]() Using Arduino C++ to program your STM32 dev board can be a really good decision if you’re just getting started with STM32 microcontrollers and would like to familiarize yourself with the STM32 hardware and computational power compared to 8-bit microcontrollers that are found in most Arduino boards.Īfter a week or so, you should have created a handful of projects using STM32 & Arduino sketches. You won’t be able to establish thorough real-time debugging sessions compared to STM32Cube IDE.Not all STM32 hardware peripherals are supported yet in the STM32DUINO core.Less control over the hardware peripherals and their configurations.Cons of STM32 Programming With Arduino IDE Even more complex projects can be implemented using the Arduino multi-file build system to organize your source code files, use timers and interrupts to achieve a specific timing behavior, and much more.You can familiarize yourself with the STM32 hardware using the Arduino C++ built-in libraries to create some easy test demo projects.Ease of programming your STM32 board in Arduino C++ like any Arduino board.Pros of STM32 Programming With Arduino IDE On the other hand, you’ll like and enjoy the ease of use and wide library support for almost every sensor and module which is a huge positive point when it comes to programming your STM32 using Arduino. Coming from a low-level embedded-C programming perspective, you may feel your application a bit more bloated than usual but it’s way better compared to something like MicroPython for instance. STM32 programming with Arduino C++ is a less conservative way of programming STM32 microcontrollers. Check this STM32 GPIO tutorial for more information. Don’t also use pull-ups or pull-downs when working with 5v. So you need to be careful when working with STM32 microcontrollers so as not to damage the IO pins by applying 5v to a 3.3v pin that’s not 5v tolerant. The GPIO pins in STM32 microcontrollers are by default 3.3v while some pins are 5v tolerant, the rest are not. We’ll discuss this in more detail hereafter. However, any other supported STM32 dev board will also work just as fine but you’ll need to flash the corresponding Arduino bootloader that matches your STM32 part family number. You can check the natively supported STM32 microcontrollers & development boards as well as the rest of the features provided by the STM32DUINO Core.įor this tutorial, we’ll be programming STM32F103C8T6 (Blue Pill) with Arduino. The STM32 Arduino Core (STM32DUINO) provides software support for various STM32 microcontroller hardware product lines. In this tutorial, we’ll discuss how to set up your Arduino ecosystem and prepare your STM32 dev board (like stm32f103c8t6 blue pill) to be able to program it using Arduino IDE and flash some Arduino sketches to rapidly prototype any project idea you want to implement using the high computational power of STM32 microcontrollers. The STM32DUINO core provides the needed firmware device drivers that make it possible for us to use STM32-based development boards as if they were Arduino boards.
