函数说明

◆ USBD_HW_ClrStallEP()

void USBD_HW_ClrStallEP ( uint8_t ep_addr )

Clear Stall condition of a non-control endpoint.

参数

ep_addr endpoint address.

返回: None

◆ USBD_HW_GetRxDataCount()

uint16_t USBD_HW_GetRxDataCount ( uint8_t ep_addr )

Get the last received packet size of an OUT endpoint.

参数

ep_addr endpoint address (eg. 0x01).

返回: The last received packet size of an OUT endpoint.

◆ USBD_HW_IsStalled()

uint8_t USBD_HW_IsStalled ( uint8_t ep_addr )

Get stall status of non-control endpoint.

参数

ep_addr endpoint address.

返回: stall status (1: stall, 0: not stall).
