Constructor Detail

FT1_2

public FT1_2(int uartChannel,
             int direction,
             int baudrate,
             int params)
      throws IOException

Constructor

Throws:

IOException

FT1_2

public FT1_2()
      throws IOException

Default constructor. Uses RS422, 125000 baud, even parity and direction A2B.

Throws:

IOException

Method Detail

sendUDAT

public void sendUDAT(byte[] data,
                     int offset,
                     int length)
              throws IOException

Send USER-DATA to peer. This function blocks until data is send (positive ack) or throws an IO-Exception is something goes wrong! TODO: we need a time-out! TODO: sync m_uart (protect for close while sending)

Parameters:

data -

offset -

length -

Throws:

IOException

sendRESET

public void sendRESET()
               throws IOException

Sends a RESET command to peer. This function blocks until data is send (positive ack) or throws an IO-Exception is something goes wrong!

Throws:

IOException

setListener

public void setListener(FT1_2EventListener eventlistener)

Sets an FT1_2EventListener.

Parameters:

el - eventlistener to use (null to remove)

getIncomingUDat

public byte[] getIncomingUDat()
                       throws IOException

Blocks until any USER-DATA availabe and return it as byte-array. If 'close()' was called, this function throws an IOException.

Returns:

available user-data or null if close() was called

Throws:

IOException - if something bad happend (ft12 closed)

setTimeOut

public void setTimeOut(int timeInMilliseconds)

Sets the exchange timeout.

Parameters:

timeout - timeout in ms

setCharacterGuardTime

public void setCharacterGuardTime(int bits)

Sets the character guard time, i.e. the time to wait between sending two characters over the serial port. Note that this value does not change the timeout, so on altering the character guard time, the application has to take care of adjusting the timeout appropriately (i.e. if guard time is set to 8, the timeout must be approximately doubled, as communication speed is cut down by 50%.

Parameters:

bits - minimum bits to wait between two characters

close

public void close()

Stops the FT1.2 communicator.

finalize

protected void finalize()

finalize method

run

public void run()

This thread is a Event-Producer and fire events for each incoming USER-DATA (using the function 'getIncomingUDat()'). This Event-Producer only runs, if any Listener if exists, otherwise no thread is startet!

Specified by:

run in interface Runnable
