jmri.jmrix.can.adapters.lawicell.LawicellTrafficController

All Implemented Interfaces:

CanInterface

public class LawicellTrafficController
extends TrafficController

Traffic controller for the LAWICELL protocol.

Lawicell adapters use messages transmitted as an ASCII string of up to 24 characters of the form: ;ShhhhNd0d1d2d3d4d5d6d7: The S indicates a standard CAN frame hhhh is the two byte header N or R indicates a normal or remote frame d0 - d7 are the (up to) 8 data bytes
