| * @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 PCD 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 |
| (+++) __HAL_RCC_USB_OTG_FS_CLK_ENABLE(); |
| (+++) __HAL_RCC_USB_OTG_HS_CLK_ENABLE(); (For High Speed Mode) |
| |
| (##) 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(); |
