Constructor & Destructor Documentation

Can_layer()

vitroio::sdk::Can_layer::Can_layer	(	Canbus *	bus,
		uint32_t	nodeId
	)

Construct a new Can_layer object.

Parameters

bus	Pointer to Canbus object
nodeId	nodeId value

Member Function Documentation

computeCRC()

int vitroio::sdk::Can_layer::computeCRC	(	const IoVec *	iov,
		int	iovcnt,
		uint32_t *	crc_value
	)

Function computes CRC of data send via CAN bus to Crystal.

Parameters

iov	Chunks of data
iovcnt	Count of chunks
crc_value	Pointer to save CRC

Returns

int Status

getTimestamp()

uint32_t vitroio::sdk::Can_layer::getTimestamp ( )

virtual

Function sends timestamp request and returns timestamp value.

Returns

uint32_t Received timestamp

Reimplemented from vitroio::sdk::Transport_layer.

send()

int vitroio::sdk::Can_layer::send ( uint32_t  parameterId, const IoVec *  iov, int  iovcnt  )

virtual

Function sends given data.

Parameters

parameterId	Id of parameter sent
iov	Pointer to first IoVec with data to be sent IoVec
iovcnt	Count of IoVects to read

Returns

int Status of sending

Reimplemented from vitroio::sdk::Transport_layer.
