STM32F105/7xx and STM32F2xx USB OTG Driver  update History

V2.0.0 / 22-July-2011

Main +Changes

+
  • Second official version supporting STM32F105/7 and STM32F2xx devices
  • Rename the Library from "STM32_USB_HOST_Driver" to "STM32_USB_OTG_Driver"
  • Add support for STM32F2xx devices
  • Add support for Device and OTG modes
  • Change HCD layer to support High speed core
  • Change the Low level driver to support multi core support for Host mode
  • Add Stop mechanism for Host and Device modes
  • Change VBUS enabling method, to use the external or the internal VBUS when using the ULPI
