[..]
|
|
(#)Declare a HCD_HandleTypeDef handle structure, for example:
|
|
HCD_HandleTypeDef hhcd;
|
|
|
|
(#)Fill parameters of Init structure in HCD handle
|
|
|
|
(#)Call HAL_HCD_Init() API to initialize the HCD peripheral (Core, Host core, ...)
|
|
|
|
(#)Initialize the HCD low level resources through the HAL_HCD_MspInit() API:
|
|
(##) Enable the HCD/USB Low Level interface clock using the following macros
|
|
(+++) __HAL_RCC_USB_OTG_FS_CLK_ENABLE();
|
|
(+++) __HAL_RCC_USB_OTG_HS_CLK_ENABLE(); (For High Speed Mode)
|
|
(+++) __HAL_RCC_USB_OTG_HS_ULPI_CLK_ENABLE(); (For High Speed Mode)
|
|
|
|
(##) Initialize the related GPIO clocks
|
|
(##) Configure HCD pin-out
|
|
(##) Configure HCD NVIC interrupt
|
|
|
|
(#)Associate the Upper USB Host stack to the HAL HCD Driver:
|
|
(##) hhcd.pData = phost;
|
|
|
|
(#)Enable HCD transmission and reception:
|
|
(##) HAL_HCD_Start();
