STM32 MCUs

The STM32 family of 32-bit microcontrollers based on the Arm® Cortex®-M processor is designed to offer new degrees of freedom to MCU users. It offers products combining very high performance, real-time capabilities, digital signal processing, low-power / low-voltage operation, and connectivity, while maintaining full integration and ease of development.

The unparalleled range of STM32 microcontrollers, based on an industry-standard core, comes with a vast choice of tools and software to support project development, making this family of products ideal for both small projects and end-to-end platforms.

What is Arduino IDE

The open-source Arduino Software (IDE) makes it easy to write code and upload it to the board. This software can be used with any Arduino board.

Arduino IDE is a programing editor

Where is stm32 usually programmed?

We can code stm32 at:

STM32CUBEIDE

STM32CubeIDE is an all-in-one multi-OS development tool, which is part of the STM32Cube software ecosystem.

Keil C

IAR

Cocos Code IDE

we need to have driver: https://www.st.com/en/development-tools/st-link-v2.html

All of the above software are used quite commonly, but require programmers to have good knowledge with C language. So today ESPITEK guides you through a fairly familiar tool that is STM32 programming on the Arduino platform.

Install STM32 on Arduino environment to be able to program STM32 with Arduino

  1. Open Arduino IDE > File > Preferences.
  2. . At “Additional Board Manager URLs” enter https://github.com/stm32duino/BoardManagerFiles/raw/master/STM32/package_stm_index.json – Note: if a URL already exists, separate it with a “,“.
Install STM32 on Arduino environment

3. Choose Tool > Board > Boards Manager…

Board manager arduino

4. Choose “Contributed” and install “STM32 Cores“.

install stm32 cores

5. Choose board in Tool > Board to start program STM32 Arduino.

Install STM32CubeProgrammer

You need to download and install the STM32CubeProgrammer if using the Upload method via SWD (STLink), Serial or DFU.

Upload code

After the installation is complete, we can start programming with Blink example

  1. Connect the STLink charger circuit to your board.
  2. Choose “Tools > Upload Method > SWD
stm32 blink on arduino ide

3. Choose “File> Examples > 01.Basics > Blink

4. Upload
