Detailed Description

This class implements CAN bus transport layer for IoT Blocks.

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.

sendRaw()

int vitroio::sdk::Can_layer::sendRaw	(	uint32_t	parameterId,
		uint8_t *	data,
		uint8_t	nBytes )

Function sends given raw data without the IoT Block overhead.

Parameters

parameterId	Id of parameter sent
data	Pointer to the array containing the data to be sent. Only 8 bytes are allowed
nBytes	Number of bytes to be sent. If more than 8bytes are used, they will be dropped

Returns

int Status of sending
