ganlikun 0:13413ea9a877 17 ##### How to use this driver #####
ganlikun 0:13413ea9a877 18 ==============================================================================
ganlikun 0:13413ea9a877 19 [..]
ganlikun 0:13413ea9a877 20 The PCD HAL driver can be used as follows:
ganlikun 0:13413ea9a877 21
ganlikun 0:13413ea9a877 22 (#) Declare a PCD_HandleTypeDef handle structure, for example:
ganlikun 0:13413ea9a877 23 PCD_HandleTypeDef hpcd;
ganlikun 0:13413ea9a877 24
ganlikun 0:13413ea9a877 25 (#) Fill parameters of Init structure in HCD handle
ganlikun 0:13413ea9a877 26
ganlikun 0:13413ea9a877 27 (#) Call HAL_PCD_Init() API to initialize the PCD peripheral (Core, Device core, ...)
ganlikun 0:13413ea9a877 28
ganlikun 0:13413ea9a877 29 (#) Initialize the PCD low level resources through the HAL_PCD_MspInit() API:
ganlikun 0:13413ea9a877 30 (##) Enable the PCD/USB Low Level interface clock using
ganlikun 0:13413ea9a877 31 (+++) __HAL_RCC_USB_OTG_FS_CLK_ENABLE();
ganlikun 0:13413ea9a877 32 (+++) __HAL_RCC_USB_OTG_HS_CLK_ENABLE(); (For High Speed Mode)
ganlikun 0:13413ea9a877 33
ganlikun 0:13413ea9a877 34 (##) Initialize the related GPIO clocks
ganlikun 0:13413ea9a877 35 (##) Configure PCD pin-out
ganlikun 0:13413ea9a877 36 (##) Configure PCD NVIC interrupt
ganlikun 0:13413ea9a877 37
ganlikun 0:13413ea9a877 38 (#)Associate the Upper USB device stack to the HAL PCD Driver:
ganlikun 0:13413ea9a877 39 (##) hpcd.pData = pdev;
ganlikun 0:13413ea9a877 40
ganlikun 0:13413ea9a877 41 (#)Enable PCD transmission and reception:
ganlikun 0:13413ea9a877 42 (##) HAL_PCD_Start();
ganlikun 0:13413ea9a877 43
