| ##### How to use this driver ##### |
| ============================================================================== |
| [..] |
| (#)Declare a HCD_HandleTypeDef handle structure, for example: |
| HCD_HandleTypeDef hhcd; |
| |
| (#)Fill parameters of Init structure in HCD handle |
| |
| (#)Call HAL_HCD_Init() API to initialize the HCD peripheral (Core, Host core, ...) |
| |
| (#)Initialize the HCD low level resources through the HAL_HCD_MspInit() API: |
| (##) Enable the HCD/USB Low Level interface clock using the following macros |
| (+++) __HAL_RCC_USB_OTG_FS_CLK_ENABLE(); |
| (+++) __HAL_RCC_USB_OTG_HS_CLK_ENABLE(); (For High Speed Mode) |
| (+++) __HAL_RCC_USB_OTG_HS_ULPI_CLK_ENABLE(); (For High Speed Mode) |
| |
| (##) Initialize the related GPIO clocks |
| (##) Configure HCD pin-out |
| (##) Configure HCD NVIC interrupt |
| |
| (#)Associate the Upper USB Host stack to the HAL HCD Driver: |
| (##) hhcd.pData = phost; |
| |
| (#)Enable HCD transmission and reception: |
| (##) HAL_HCD_Start(); |
