lypinator | 0:bb348c97df44 | 15 | ##### How to use this driver ##### |
lypinator | 0:bb348c97df44 | 16 | ============================================================================== |
lypinator | 0:bb348c97df44 | 17 | [..] |
lypinator | 0:bb348c97df44 | 18 | The PCD HAL driver can be used as follows: |
lypinator | 0:bb348c97df44 | 19 | |
lypinator | 0:bb348c97df44 | 20 | (#) Declare a PCD_HandleTypeDef handle structure, for example: |
lypinator | 0:bb348c97df44 | 21 | PCD_HandleTypeDef hpcd; |
lypinator | 0:bb348c97df44 | 22 | |
lypinator | 0:bb348c97df44 | 23 | (#) Fill parameters of Init structure in HCD handle |
lypinator | 0:bb348c97df44 | 24 | |
lypinator | 0:bb348c97df44 | 25 | (#) Call HAL_PCD_Init() API to initialize the PCD peripheral (Core, Device core, ...) |
lypinator | 0:bb348c97df44 | 26 | |
lypinator | 0:bb348c97df44 | 27 | (#) Initialize the PCD low level resources through the HAL_PCD_MspInit() API: |
lypinator | 0:bb348c97df44 | 28 | (##) Enable the PCD/USB Low Level interface clock using |
lypinator | 0:bb348c97df44 | 29 | (+++) __HAL_RCC_USB_OTG_FS_CLK_ENABLE(); |
lypinator | 0:bb348c97df44 | 30 | (+++) __HAL_RCC_USB_OTG_HS_CLK_ENABLE(); (For High Speed Mode) |
lypinator | 0:bb348c97df44 | 31 | |
lypinator | 0:bb348c97df44 | 32 | (##) Initialize the related GPIO clocks |
lypinator | 0:bb348c97df44 | 33 | (##) Configure PCD pin-out |
lypinator | 0:bb348c97df44 | 34 | (##) Configure PCD NVIC interrupt |
lypinator | 0:bb348c97df44 | 35 | |
lypinator | 0:bb348c97df44 | 36 | (#)Associate the Upper USB device stack to the HAL PCD Driver: |
lypinator | 0:bb348c97df44 | 37 | (##) hpcd.pData = pdev; |
lypinator | 0:bb348c97df44 | 38 | |
lypinator | 0:bb348c97df44 | 39 | (#)Enable PCD transmission and reception: |
lypinator | 0:bb348c97df44 | 40 | (##) HAL_PCD_Start(); |
