- * @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 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_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();
-
