The program CM11AEvents can be started by entering the following command line:
java CM11AEvents [-port serial_port]
Where:
-port serial_port Set the serial port that the CM11A can be contacted on. Default: COM2
Example
Running CM11AEvents on the default serial port of 'COM2'.
java CM11AEvents
Running CM11AEvents on serial port 'COM1'.
java CM11AEvents -port COM1
Code
The source code for CM11AEvents.java
can be found in the samples/CM11AEvents directory. The class implements both
the CM11AListener
interface and the
CM11AStatusListener
interface. After allocating the
CM11A
object, the CM11AEvents
object registers itself
as a CM11AListener
and a CM11AStatusListener
with
the method calls addCM11AListener
and
addCM11AStatusListener
respectively.
A simple command interface is provided to facilitate event generation. If
the <Enter> key is pressed, the CM11A device will be queried for its
current status. When the status is retrieved, the status
listener
method is called with the CM11AStatusEvent
which is printed
to standard out.
If the CM11A device has been programmed with any macros, you can invoke
the macro and get a CM11AEvent
indicating that a macro was
invoked.
You can also simulate a power failure to the CM11AEvent
indicating
resumption from a power failure. You can do this by monentarilly unplugging
the CM11A device from the outlet. After plugging the device back in, a
CM11AEvent
indicating a power failure should occur. When a
power failure event does occur, the CM11A expects to receive a "set clock"
message before it will continue processing commands. The CM11A
class has the ability to automatically generate this command after recovering
from a power failure. The autorecovery can be turned off however, allowing
manual handling of the power failure. The powerFailure
method
show how to handle both cases. You can test either case by turning autorecovery
on or off by typing "auto" or "noauto" in the simple interface.
When done with the test, type "exit" to terminate the program.
