Constructor Detail

IO

public IO()

Method Detail

delay

public static void delay(long lMilliSeconds)

Wait a specified time. The routine uses Thread.sleep so below 20 ms timing becomes very erraneous, but works fine for longer times

Parameters:

lMilliSeconds - number of milliseconds to wait

init

public static boolean init()

Initialize. Before calling the emulated IO routines, use one of the init routines to set the host name and port number of the server emulating the HW.

init

public static boolean init(int newPort)

init

public static boolean init(String newHost)

init

public static boolean init(String newHost,
                           int newPort)

readShort

public static short readShort(int address)

readShort

public static short readShort(short address)

Read a short value (16-bits) from an I/O port.

Parameters:

address - port address (16-bits)

Returns:

short value (16-bits)

writeShort

public static void writeShort(int address,
                              int value)

writeShort

public static void writeShort(short address,
                              short value)

Write a short value (16-bits) to an I/O port.

Parameters:

address - port address (16-bits)

value - short value (16-bits)
