Copyright 2017 STMicroelectronics

 

Update History

V2.2.1 / 17-March-2018

Main Changes

  • usb_core.c
    • Bug Fix: Update VBUS sensing support for STM32F446xx and STM32F469 devices
    • Bug Fix: deactivate endpoints per endpoint number
  • usb_reg.h
    • Add bit mapping of GCCFG register for STM32F446xx and STM32F469 devices

V2.2.0 / 9-November-2015

Main Changes

  • Add support of  STM32F469/479xx and  STM32F446 devices
  • usb_dcd_int.c
    • Bug Fix: Masking the TxFIFOempty interrupt of the endpoint after finishing writing data packet to TxFIFO in DCD_WriteEmptyTxFifo function
    • Bug Fix: The USB TRD (Turnaround) is configured depending on AHB frequency used by application.
    • Bug Fix: Handle multi-packet for OUT transfer with DMA in HS mode
    • Remove CLEAR_IN_EP_INTR(epnum, emptyintr) in USBD_OTG_EP1IN_ISR_Handler and DCD_HandleInEP_ISR
    • Correct PCFCCTL register access
  • usb_core.c
    • USB_OTG_HC_Halt function: Modify Channel halt function to disable the channel at the end
    • Correct PCFCCTL register access
    • Bug Fix: Handle multi-packet for OUT transfer with DMA in HS mode
    • Bug Fix: Keep the disconnect interrupt maskedIn function  USB_OTG_EnableHostInt for correct handling of connection/disconnection
    • In function USB_OTG_ResetPort change reset time to 100ms instead of 10ms for better stability during enumeration
  • usb_hcd.c
    •  Add function HCD_IsPortEnabled to check portenabled for correct handling of connection/disconnection
  • usb_hcd_int.c 
    • Remove USB_OTG_ResetPort(pdev) calling 
    • Update USB_OTG_USBH_handle_port_ISR for correct handling of connection/disconnection
    • Disconnect interrupt is unmasked after a connection
    • Creation of PortEnabled event (need to wait for this event before starting enumerating device)
    • Halt channel and restart transfer is removed When using DMA (HS) In case of NAK or NYET in USB_OTG_USBH_handle_hc_n_Out_ISR and USB_OTG_USBH_handle_hc_n_In_ISR
    • Clearing the NAK interrupt flag before re-enabling the channel for a new transfer in USB_OTG_USBH_handle_hc_n_In_ISR function

V2.1.0 / 19-March-2012

Main Changes

  • Official support of STM32F4xx devices
  • All source files: license disclaimer text update and add link to the License file on ST Internet
  • Unmask Session request interrupt to handle the connect event during the core start-up
  • Remove any reference to the USB HS external I2C PHY
  • Update optimization pragma for AR Compiler
  • Handle Correctly the Low Speed device connection in HS mode
  • Add a wrapper to isolate the library from the low level driver: connection done through ISR structure
  • Miscellaneous bug fix

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

V1.0.0 - 11/29/2010
