Enumeration Type Documentation

◆ Endpoint_WaitUntilReady_ErrorCodes_t

Enum for the possible error return codes of the Endpoint_WaitUntilReady() function.

Enumerator
ENDPOINT_READYWAIT_NoError 

Endpoint is ready for next packet, no error.

ENDPOINT_READYWAIT_EndpointStalled 

The endpoint was stalled during the stream transfer by the host or device.

ENDPOINT_READYWAIT_DeviceDisconnected 

Device was disconnected from the host while waiting for the endpoint to become ready.

ENDPOINT_READYWAIT_BusSuspended 

The USB bus has been suspended by the host and no USB endpoint traffic can occur until the bus has resumed.

ENDPOINT_READYWAIT_Timeout 

The host failed to accept or send the next packet within the software timeout period set by the USB_STREAM_TIMEOUT_MS macro.

ENDPOINT_READYWAIT_NoError 

Endpoint is ready for next packet, no error.

ENDPOINT_READYWAIT_EndpointStalled 

The endpoint was stalled during the stream transfer by the host or device.

ENDPOINT_READYWAIT_DeviceDisconnected 

Device was disconnected from the host while waiting for the endpoint to become ready.

ENDPOINT_READYWAIT_BusSuspended 

The USB bus has been suspended by the host and no USB endpoint traffic can occur until the bus has resumed.

ENDPOINT_READYWAIT_Timeout 

The host failed to accept or send the next packet within the software timeout period set by the USB_STREAM_TIMEOUT_MS macro.

ENDPOINT_READYWAIT_NoError 

Endpoint is ready for next packet, no error.

ENDPOINT_READYWAIT_EndpointStalled 

The endpoint was stalled during the stream transfer by the host or device.

ENDPOINT_READYWAIT_DeviceDisconnected 

Device was disconnected from the host while waiting for the endpoint to become ready.

ENDPOINT_READYWAIT_BusSuspended 

The USB bus has been suspended by the host and no USB endpoint traffic can occur until the bus has resumed.

ENDPOINT_READYWAIT_Timeout 

The host failed to accept or send the next packet within the software timeout period set by the USB_STREAM_TIMEOUT_MS macro.

Function Documentation

◆ Endpoint_BytesInEndpoint()

static uint16_t Endpoint_BytesInEndpoint ( void  )
inlinestatic

Indicates the number of bytes currently stored in the current endpoint's selected bank.

Returns
Total number of bytes in the currently selected Endpoint's FIFO buffer.

◆ Endpoint_WaitUntilReady()

uint8_t Endpoint_WaitUntilReady ( void  )

Spin-loops until the currently selected non-control endpoint is ready for the next packet of data to be read or written to it.

Note
This routine should not be called on CONTROL type endpoints.
Returns
A value from the Endpoint_WaitUntilReady_ErrorCodes_t enum.
