- [..]
- (#)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();
- (##) 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();
