STM32 core API reference

This is the source-level API reference of the Arduino core for STM32 based boards, generated with Doxygen from the comments in the core, its built-in libraries, the STM32 system files and the board variants.

For setup, supported boards, tutorials and the Arduino API, see the STM32duino documentation. Use the version selector in the sidebar to switch between the development (dev) and the released versions.

Where to start

• Classes: classes and structures such as HardwareTimer, HardwareSerial or TwoWire.
• Files: browse the documented source files.
• Functions: documented C functions.

The ST HAL, LL and CMSIS drivers, the middlewares and the ArduinoCore-API sources are not part of this reference: see their own documentation.
