sahilmgandhi 18:6a4db94011d3 17 ##### How to use this driver #####
sahilmgandhi 18:6a4db94011d3 18 ==============================================================================
sahilmgandhi 18:6a4db94011d3 19 [..]
sahilmgandhi 18:6a4db94011d3 20 The PCD HAL driver can be used as follows:
sahilmgandhi 18:6a4db94011d3 21
sahilmgandhi 18:6a4db94011d3 22 (#) Declare a PCD_HandleTypeDef handle structure, for example:
sahilmgandhi 18:6a4db94011d3 23 PCD_HandleTypeDef hpcd;
sahilmgandhi 18:6a4db94011d3 24
sahilmgandhi 18:6a4db94011d3 25 (#) Fill parameters of Init structure in HCD handle
sahilmgandhi 18:6a4db94011d3 26
sahilmgandhi 18:6a4db94011d3 27 (#) Call HAL_PCD_Init() API to initialize the PCD peripheral (Core, Device core, ...)
sahilmgandhi 18:6a4db94011d3 28
sahilmgandhi 18:6a4db94011d3 29 (#) Initialize the PCD low level resources through the HAL_PCD_MspInit() API:
sahilmgandhi 18:6a4db94011d3 30 (##) Enable the PCD/USB Low Level interface clock using
sahilmgandhi 18:6a4db94011d3 31 (+++) __HAL_RCC_USB_OTG_FS_CLK_ENABLE();
sahilmgandhi 18:6a4db94011d3 32 (+++) __HAL_RCC_USB_OTG_HS_CLK_ENABLE(); (For High Speed Mode)
sahilmgandhi 18:6a4db94011d3 33
sahilmgandhi 18:6a4db94011d3 34 (##) Initialize the related GPIO clocks
sahilmgandhi 18:6a4db94011d3 35 (##) Configure PCD pin-out
sahilmgandhi 18:6a4db94011d3 36 (##) Configure PCD NVIC interrupt
sahilmgandhi 18:6a4db94011d3 37
sahilmgandhi 18:6a4db94011d3 38 (#)Associate the Upper USB device stack to the HAL PCD Driver:
sahilmgandhi 18:6a4db94011d3 39 (##) hpcd.pData = pdev;
sahilmgandhi 18:6a4db94011d3 40
sahilmgandhi 18:6a4db94011d3 41 (#)Enable PCD transmission and reception:
sahilmgandhi 18:6a4db94011d3 42 (##) HAL_PCD_Start();
