******************************************************************************
* @file stm32f1xx_hal_pcd.c
* @author MCD Application Team
* @brief PCD HAL module driver.
* This file provides firmware functions to manage the following
* functionalities of the USB Peripheral Controller:
* + Initialization and de-initialization functions
* + IO operation functions
* + Peripheral Control functions
* + Peripheral State functions
*
@verbatim
==============================================================================
##### How to use this driver #####
==============================================================================
[..]
The PCD HAL driver can be used as follows:
(#) Declare a PCD_HandleTypeDef handle structure, for example:
PCD_HandleTypeDef hpcd;
(#) Fill parameters of Init structure in HCD handle
(#) Call HAL_PCD_Init() API to initialize the HCD peripheral (Core, Device core, ...)
(#) Initialize the PCD low level resources through the HAL_PCD_MspInit() API:
(##) Enable the PCD/USB Low Level interface clock using the following macro
(+++) __HAL_RCC_USB_CLK_ENABLE(); For USB Device FS peripheral available
on STM32F102xx and STM32F103xx devices
(+++) __HAL_RCC_USB_OTG_FS_CLK_ENABLE(); For USB OTG FS peripheral available
on STM32F105xx and STM32F107xx devices
(##) 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 HCD transmission and reception:
(##) HAL_PCD_Start();
