  • STM32L4x2xx
  • And others...


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.


Example applications may be found in the individual device HALs:
