(#) Initialize the PCD low level resources through the HAL_PCD_MspInit() API: (##) Enable the PCD/USB Low Level interface clock using (+++) __HAL_RCC_USB_CLK_ENABLE(); For USB Device only FS peripheral (##) Initialize the related GPIO clocks (##) Configure PCD pin-out (##) Configure PCD NVIC interrupt (#)Associate the Upper USB device stack to the HAL PCD Driver: (##) hpcd.pData = pdev; (#)Enable PCD transmission and reception: (##) HAL_PCD_Start(); @endverbatim ****************************************************************************** * @attention * *
