ALF Debugging Tool

ALF is a tool for debugging waveforms that is included with current distributions of OSSIE and described in the Installation and User Guide.

The remainder of this page needs to be updated.


Here are the instructions for installing ALF and its dependencies. Remember that commands prefixed with $ implies the command should be run with regular permissions, while # implies the command should be run as root.

  1. Install customInterfaces: experimental/customInterfaces/trunk/customInterfaces
    $ svn co
    $ cd customInterfaces
    $ ./reconf
    $ ./configure
    # make install
  2. Create python bindings for IDL
    $ cd /usr/local/include/standardinterfaces
    # mkdir idl_py
    # cd idl_py
    # omniidl -bpython -I../.. ../*idl

If the omniidl command above returns an error similar to "No module named python" you might need to use the -p option to specify a path for it, e.g:

#omniidl -p/usr/local/lib/python2.4/site-packages  -bpython -I../.. ../*idl         
  1. For the time being, you may need to add the following directories to your ossie.pth file:
  2. For the plot feature to work, you will need python\'s numpy package. Numpy is used in calculating FFTs.
    1. One good place to find numpy is sourceforge. Download numpy-1.0.1.tar.gz. After unzipping and untarring the file, go to a terminal and navigate to the numpy-1.0.1 directory. From there run
      $ python install
    2. Alternatively, numpy can also be installed through Yum, viz
      # yum install numpy
  3. Get the source code for ALF. Execute the following commands while in your desired source directory:
    $ svn co
    $ cd alf
    $ ./reconf
    $ ./configure
    $ make install
  4. Add to both /sdr and /sdr/tools,
    $ touch /sdr/
    $ touch /sdr/tools/

Running ALF

  1. Start if you have not already:
  2. Start nodeBooter
    $ nodeBooter -D -d path/to/DeviceManager.dmd.xml
  3. Navigate to the alf directory (default is /sdr/tools/alf), and start ALF:
    $ python

The top left window will list your available waveforms, which must be installed to /sdr/waveforms. Left click on the desired waveform, and select "install".

Installed waveforms are displayed in the bottom-left window. To view the waveform, right click on it in the bottom-left window and select "display". Your waveform will then be displayed on the right window. Note that in the current version of ALF, all devices will be ignored in the display.

When the waveform is displayed, you can right-click on the ports to use the various analysis tools (e.g., plot).
