STM32 core sources files location

The install directory of Arduino IDE can be found here:

  • /home/\<USERNAME>/.arduino15/ (Linux)
  • /Users/\<USERNAME>/Library/Arduino15/ (Mac)
  • C:\Users\<USERNAME>\AppData\Local\Arduino15\ (Windows 10 and 11)

First make sure you have installed the stm32 core using the Arduino Boards Manager.

The stm32 core files can then be found in this directory:

<Arduino IDE install directory>/packages/STMicroelectronics/hardware/stm32/2.8.1.

Note

The 2.8.1 changes depending on your installed stm32 core version.

STM32 Tools files location

Go to the Arduino IDE install directory. See above.

Then, go to the <Arduino install directory>/packages/STMicroelectronics/tools/STM32Tools/2.2.3 directory.

Note

The 2.2.3 changes depending on your installed stm32 tools version.
