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();
lypinator 0:bb348c97df44 41
