Package jmri.jmrix.powerline.dmx512

Class SpecificTrafficController

java.lang.Object

jmri.jmrix.AbstractMRTrafficController

jmri.jmrix.powerline.SerialTrafficController

jmri.jmrix.powerline.dmx512.SpecificTrafficController

All Implemented Interfaces:

SerialInterface

public class SpecificTrafficController
extends SerialTrafficController

Converts Stream-based I/O to/from messages. The "SerialInterface" side sends/receives message objects.

The connection to a SerialPortController is via a pair of *Streams, which then carry sequences of characters for transmission. Note that this processing is handled in an independent thread.

public SpecificTrafficController(SerialSystemConnectionMemo memo)

Method Detail

setDmxIntensity

public boolean setDmxIntensity(int unitId,
                               byte intensityValue)

set value in dmxArray

Parameters:

unitId - offset in dmxArray

intensityValue - value to put in dmxArray

Returns:

true when values ok

transmitLoop

protected void transmitLoop()

Description copied from class: AbstractMRTrafficController

Permanent loop for the transmit thread.

Overrides:

transmitLoop in class AbstractMRTrafficController

receiveLoop

public void receiveLoop()

Description copied from class: AbstractMRTrafficController

Handle incoming characters. This is a permanent loop, looking for input messages in character form on the stream connected to the PortController via AbstractMRTrafficController.connectPort(AbstractPortController).

Each turn of the loop is the receipt of a single message.

Overrides:

receiveLoop in class AbstractMRTrafficController

getNumberOfIntensitySteps

public int getNumberOfIntensitySteps()

This system provides 256 dim steps

Overrides:

getNumberOfIntensitySteps in class SerialTrafficController

Returns:

By default, dimming not available.

sendDmxSequence

public boolean sendDmxSequence(int unitid,
                               byte newStep)

Send a sequence of Dmx messages

Makes call to update array

Overrides:

sendDmxSequence in class SerialTrafficController

Parameters:

unitid - which light

newStep - new intesity value

Returns:

true on success
