saloutos 0:083111ae2a11 19 [..]
saloutos 0:083111ae2a11 20 The PCD HAL driver can be used as follows:
saloutos 0:083111ae2a11 21
saloutos 0:083111ae2a11 22 (#) Declare a PCD_HandleTypeDef handle structure, for example:
saloutos 0:083111ae2a11 23 PCD_HandleTypeDef hpcd;
saloutos 0:083111ae2a11 24
saloutos 0:083111ae2a11 25 (#) Fill parameters of Init structure in HCD handle
saloutos 0:083111ae2a11 26
saloutos 0:083111ae2a11 27 (#) Call HAL_PCD_Init() API to initialize the PCD peripheral (Core, Device core, ...)
saloutos 0:083111ae2a11 28
saloutos 0:083111ae2a11 29 (#) Initialize the PCD low level resources through the HAL_PCD_MspInit() API:
saloutos 0:083111ae2a11 30 (##) Enable the PCD/USB Low Level interface clock using
saloutos 0:083111ae2a11 31 (+++) __HAL_RCC_USB_OTG_FS_CLK_ENABLE();
saloutos 0:083111ae2a11 32 (+++) __HAL_RCC_USB_OTG_HS_CLK_ENABLE(); (For High Speed Mode)
saloutos 0:083111ae2a11 33
saloutos 0:083111ae2a11 34 (##) Initialize the related GPIO clocks
saloutos 0:083111ae2a11 35 (##) Configure PCD pin-out
saloutos 0:083111ae2a11 36 (##) Configure PCD NVIC interrupt
saloutos 0:083111ae2a11 37
saloutos 0:083111ae2a11 38 (#)Associate the Upper USB device stack to the HAL PCD Driver:
saloutos 0:083111ae2a11 39 (##) hpcd.pData = pdev;
saloutos 0:083111ae2a11 40
saloutos 0:083111ae2a11 41 (#)Enable PCD transmission and reception:
saloutos 0:083111ae2a11 42 (##) HAL_PCD_Start();
