Class pinball.io.RS232SDD16 

java.lang.Object
   |
   +----pinball.io.RS232SDD16
public class RS232SDD16
extends Object
Controls for the RS232SDD16 data IO device. Currently the LSB is the output part of the I/O unit sending data to the pinball machine. The MSB is used to read the data from the I/O device.

Variable Index

o ALL
A bitset with all the bits on.
o WORDSIZE
Size of word for the device.
o ZERO
A zero bitset.

Constructor Index

o RS232SDD16(String)
Create the IO device at the port specified.

Method Index

o defineLines(byte, byte)
Define the IO lines in the system.
o flushInputData()
Clear any data waiting to be read.
o flushOutputData()
Clear any commands waiting to go out.
o main(String[])
Used to test the device.
o readConfiguration()
Read the configuration of the device.
o readOutputLines()
Read the output lines.
o requestRead()
Request a read from the output lines.
o resetOutputLines(BitSet, BitSet)
Clear the output lines on the device.
o setOutputLines(BitSet, BitSet)
Set the output lines on the device.
o setPowerupStates(byte, byte)
Define the IO lines inital power on state.
o turnOff()
Clean out the data, so that all the devices are turned off.

Variables

o WORDSIZE 
 public final int WORDSIZE
Size of word for the device.

o ZERO 
 public BitSet ZERO
A zero bitset.

o ALL 
 public BitSet ALL
A bitset with all the bits on.

Constructors

o RS232SDD16 
 public RS232SDD16(String port)
Create the IO device at the port specified. param port serial port location.

Methods

o resetOutputLines 
 public synchronized void resetOutputLines(BitSet msb,
                                           BitSet lsb) throws IOException
Clear the output lines on the device. param msb the most significant bit. param lsb the least significant bit.

o setOutputLines 
 public synchronized void setOutputLines(BitSet msb,
                                         BitSet lsb) throws IOException
Set the output lines on the device. param msb the most significant bit. param lsb the least significant bit.

o readOutputLines 
 public synchronized byte[] readOutputLines() throws IOException
Read the output lines. return the bytes reads in from the device.

o requestRead 
 public synchronized void requestRead() throws IOException
Request a read from the output lines.

o defineLines 
 public synchronized void defineLines(byte msb,
                                      byte lsb) throws IOException
Define the IO lines in the system. 1 mean output, 0 means input. param msb the most significant bit. param lsb the least significant bit.

o setPowerupStates 
 public synchronized void setPowerupStates(byte msb,
                                           byte lsb) throws IOException
Define the IO lines inital power on state. param msb the most significant bit. param lsb the least significant bit.

o readConfiguration 
 public synchronized byte[] readConfiguration() throws IOException
Read the configuration of the device. return The bytes in the configuration. IO Definitions followed by Powerup states.

o turnOff 
 public synchronized void turnOff()
Clean out the data, so that all the devices are turned off.

o main 
 public static void main(String args[])
Used to test the device.

o flushInputData 
 public synchronized void flushInputData()
Clear any data waiting to be read.

o flushOutputData 
 public synchronized void flushOutputData()
Clear any commands waiting to go out.
