stm32-usbd

usb-device implementation for STM32 microcontrollers.

This project is a successor to the great work started by @mvirkkunen.

Supported microcontrollers

  • STM32F042xx
  • STM32F048xx
  • STM32F072xx
  • STM32F078xx
  • STM32F103xx
  • STM32F303xC
  • STM32L0x2xx
  • STM32L4x2xx
  • And others...

Usage

This driver is intended for use through a device hal library. Such hal library should implement UsbPeripheral for the corresponding USB peripheral object. This trait declares all the peripheral properties that may vary from one device family to the other.

Examples

Example applications may be found in the individual device HALs:
