Method Detail

getTxAcknowledgeBuffer

public CANMessageBuffer getTxAcknowledgeBuffer()

Description copied from interface: CANDriver

Accessor method for transmit acknowledge buffer.

Specified by:

getTxAcknowledgeBuffer in interface CANDriver

Returns:

CAN buffer

getMessageBuffer

public CANMessageBuffer getMessageBuffer()

Description copied from interface: CANDriver

Accessor method for receive buffer. Note that receive buffer is only serviced if no callback method has been registered.

Specified by:

getMessageBuffer in interface CANDriver

Returns:

true if successful

sendMessage

public boolean sendMessage(CANMessage cmsg)

Description copied from interface: CANDriver

Sends CAN message.

Specified by:

sendMessage in interface CANDriver

Parameters:

cmsg - Message

Returns:

true if successful

callBack

public void callBack(CANMessage cmsg)

Description copied from interface: CANCallBack

Function that is called if a CAN message is received.

Specified by:

callBack in interface CANCallBack

Parameters:

cmsg - CAN message

registerCallBack

public void registerCallBack(CANCallBack canCB)

Description copied from interface: CANDriver

Registers method to be called when CAN message is received.

Specified by:

registerCallBack in interface CANDriver

Parameters:

canCB - callback

getNumberOfFilters

public int getNumberOfFilters()

Description copied from interface: CANDriver

Returns the number of acceptance filters available.

Specified by:

getNumberOfFilters in interface CANDriver
