Typedef Documentation

◆ SbgEComHandle

typedef struct _SbgEComHandle SbgEComHandle

Interface structure pre-definition.

◆ SbgEComReceiveLogFunc

typedef SbgErrorCode(* SbgEComReceiveLogFunc) (SbgEComHandle *pHandle, SbgEComClass msgClass, SbgEComMsgId msg, const SbgEComLogUnion *pLogData, void *pUserArg)

Callback definition called each time a new log is received.

Parameters

[in]	pHandle	Valid handle on the sbgECom instance that has called this callback.
[in]	msgClass	Class of the message we have received
[in]	msg	Message ID of the log received.
[in]	pLogData	Contains the received log data as an union.
[in]	pUserArg	Optional user supplied argument.

Returns: SBG_NO_ERROR if the received log has been used successfully.

Function Documentation

◆ sbgEComInit()

SbgErrorCode sbgEComInit	(	SbgEComHandle *	pHandle,
		SbgInterface *	pInterface )

Initialize the protocol system used to communicate with the product and return the created handle.

Parameters

[out]	pHandle	Pointer used to store the allocated and initialized sbgECom handle.
[in]	pInterface	Interface to use for read/write operations.

Returns: SBG_NO_ERROR if we have initialized the protocol system.

◆ sbgEComClose()

SbgErrorCode sbgEComClose ( SbgEComHandle * pHandle )

Close the protocol system and release associated memory.

Parameters

[in] pHandle A valid sbgECom handle to close.

Returns: SBG_NO_ERROR if we have closed and released the sbgECom system.

◆ sbgEComHandleOneLog()

SbgErrorCode sbgEComHandleOneLog ( SbgEComHandle * pHandle )

Try to parse one log from the input interface and then return.

Parameters

[in] pHandle A valid sbgECom handle.

Returns: SBG_NO_ERROR if no error occurs during incoming log parsing.

◆ sbgEComHandle()

SbgErrorCode sbgEComHandle ( SbgEComHandle * pHandle )

Handle all incoming logs until no more log are available in the input interface.

Parameters

[in] pHandle A valid sbgECom handle.

Returns: SBG_NO_ERROR if no error occurs during incoming logs parsing.

◆ sbgEComPurgeIncoming()

SbgErrorCode sbgEComPurgeIncoming ( SbgEComHandle * pHandle )

Purges any pending data from both the interface RX buffer and the sbgECom internal RX work buffer.

This is useful after an unexpected disruption in the program flow, allowing the caller to discard any corrupted or incomplete data that may have been received.

The function repeatedly reads and discards incoming data for a limited time window. It provides a best-effort drain of the underlying interface buffers, but cannot strictly distinguish between data sent before and after the purge, especially if the device is continuously transmitting.

Note: This function is blocking and may take up to approximately 500 ms while actively reading and discarding incoming data.

Parameters

[in] pHandle A valid sbgECom handle.

Returns: SBG_NO_ERROR if all pending incoming data was successfully purged.

◆ sbgEComSetReceiveLogCallback()

void sbgEComSetReceiveLogCallback	(	SbgEComHandle *	pHandle,
		SbgEComReceiveLogFunc	pReceiveLogCallback,
		void *	pUserArg )

Define the callback that should be called each time a new binary log is received.

Parameters

[in]	pHandle	A valid sbgECom handle.
[in]	pReceiveLogCallback	Pointer on the callback to call when a new log is received.
[in]	pUserArg	Optional user argument that will be passed to the callback method.

◆ sbgEComSetCmdTrialsAndTimeOut()

void sbgEComSetCmdTrialsAndTimeOut	(	SbgEComHandle *	pHandle,
		uint32_t	numTrials,
		uint32_t	cmdDefaultTimeOut )

Define the default number of trials that should be done when a command is send to the device as well as the time out.

Parameters

[in]	pHandle	A valid sbgECom handle.
[in]	numTrials	Number of trials when a command is sent (starting at 1).
[in]	cmdDefaultTimeOut	Default time out in milliseconds to wait to receive an answer from the device.

◆ sbgEComErrorToString()

void sbgEComErrorToString	(	SbgErrorCode	errorCode,
		char	errorMsg[256] )

Convert an error code into a human readable string.

Parameters

[in]	errorCode	The errorCode to convert into a string.
[out]	errorMsg	String buffer used to hold the error string.
