26 ##### How to use this driver #####
27 ==============================================================================
28 [..]
29 The PCD HAL driver can be used as follows:
30
31 (#) Declare a PCD_HandleTypeDef handle structure, for example:
32 PCD_HandleTypeDef hpcd;
33
34 (#) Fill parameters of Init structure in HCD handle
35
36 (#) Call HAL_PCD_Init() API to initialize the PCD peripheral (Core, Device core, ...)
37
38 (#) Initialize the PCD low level resources through the HAL_PCD_MspInit() API:
39 (##) Enable the PCD/USB Low Level interface clock using
40 (+++) __HAL_RCC_USB_CLK_ENABLE(); For USB Device FS peripheral
41 (+++) __HAL_RCC_USB_OTG_FS_CLK_ENABLE();
42 (+++) __HAL_RCC_USB_OTG_HS_CLK_ENABLE(); (For High Speed Mode)
43
44 (##) Initialize the related GPIO clocks
45 (##) Configure PCD pin-out
46 (##) Configure PCD NVIC interrupt
47
48 (#)Associate the Upper USB device stack to the HAL PCD Driver:
49 (##) hpcd.pData = pdev;
50
51 (#)Enable PCD transmission and reception:
52 (##) HAL_PCD_Start();
