Parameters hhcd : HCD handle Return values HAL status Notes None. HAL_HCD_HC_Init Function Name HAL_StatusTypeDef HAL_HCD_HC_Init ( HCD_HandleTypeDef * hhcd, uint8_t ch_num, uint8_t epnum, uint8_t dev_address, uint8_t speed, uint8_t ep_type, uint16_t mps) Function Description Initialize a host channel. Parameters hhcd : HCD handle ch_num : Channel number. This parameter can be a value from 1 to 15 epnum : Endpoint number. This parameter can be a value from 1 to 15 dev_address : : Current device address This parameter can be a value from 0 to 255 speed : Current device speed. This parameter can be one of these values: HCD_SPEED_HIGH: High speed mode, HCD_SPEED_FULL: Full speed mode, HCD_SPEED_LOW: Low speed mode ep_type : Endpoint Type.
