- * @file stm32f7xx_hal_pcd.c
- * @author MCD Application Team
- * @version V1.0.4
- * @date 09-December-2015
- * @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();
-

+ * @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();
+
