Function Documentation

sbgInterfaceSerialChangeBaudrate()

SbgErrorCode sbgInterfaceSerialChangeBaudrate	(	SbgInterface *	pHandle,
		uint32	baudRate
	)

Change the serial interface baud rate immediatly.

Parameters

[in]	handle	Valid handle on an initialized interface.
[in]	baudRate	The new baudrate to apply in bps.

Returns

SBG_NO_ERROR if everything is OK

Definition at line 300 of file sbgInterfaceSerialUnix.c.

sbgInterfaceSerialCreate()

SbgErrorCode sbgInterfaceSerialCreate	(	SbgInterface *	pHandle,
		const char *	deviceName,
		uint32	baudRate
	)

Initialize a serial interface for read and write operations.

Parameters

[in]	pHandle	Pointer on an allocated interface instance to initialize.
[in]	deviceName	Serial interface location (COM21 , /dev/ttys0, depending on platform).
[in]	baudRate	Serial interface baud rate in bps.

Returns

SBG_NO_ERROR if the interface has been created.

Definition at line 83 of file sbgInterfaceSerialUnix.c.

sbgInterfaceSerialDestroy()

SbgErrorCode sbgInterfaceSerialDestroy

(

SbgInterface *

pHandle

)

Destroy an interface initialized using sbgInterfaceSerialCreate.

Parameters

[in]

pInterface

Valid handle on an initialized interface.

Returns

SBG_NO_ERROR if the interface has been closed and released.

Definition at line 228 of file sbgInterfaceSerialUnix.c.

sbgInterfaceSerialFlush()

SbgErrorCode sbgInterfaceSerialFlush

(

SbgInterface *

pHandle

)

Flush the RX and TX buffers (remove all old data)

Parameters

[in]

handle

Valid handle on an initialized interface.

Returns

SBG_NO_ERROR if everything is OK

Definition at line 262 of file sbgInterfaceSerialUnix.c.

sbgInterfaceSerialGetBaudRateConst()

uint32 sbgInterfaceSerialGetBaudRateConst

(

uint32

baudRate

)

Returns the right unix baud rate const according to a baud rate value.

Parameters

[in]

baudRate

The baud rate value (ie 115200).

Returns

The Unix baud rate constant.

Definition at line 20 of file sbgInterfaceSerialUnix.c.

sbgInterfaceSerialRead()

SbgErrorCode sbgInterfaceSerialRead	(	SbgInterface *	pHandle,
		void *	pBuffer,
		size_t *	pReadBytes,
		size_t	bytesToRead
	)

Try to read some data from an interface.

Parameters

[in]	pHandle	Valid handle on an initialized interface.
[in]	pBuffer	Pointer on an allocated buffer that can hold at least bytesToRead bytes of data.
[out]	pReadBytes	Pointer on an uint32 used to return the number of read bytes.
[in]	bytesToRead	Number of bytes we would like to read.

Returns

SBG_NO_ERROR if no error occurs, please check the number of received bytes.

Definition at line 433 of file sbgInterfaceSerialUnix.c.

sbgInterfaceSerialWrite()

SbgErrorCode sbgInterfaceSerialWrite	(	SbgInterface *	pHandle,
		const void *	pBuffer,
		size_t	bytesToWrite
	)

Try to write some data to an interface.

Parameters

[in]	pHandle	Valid handle on an initialized interface.
[in]	pBuffer	Pointer on an allocated buffer that contains the data to write
[in]	bytesToWrite	Number of bytes we would like to write.

Returns

SBG_NO_ERROR if all bytes have been written successfully.
