OpenVisualizer is the primary tool for plugging your OpenWSN network into the Internet.

Features

• Connects your OpenWSN network to the Internet over a virtual interface (both Windows and Linux).
• portable across popular operating systems.
• Shows the internal state (neighbor table, scheduling table, queue, etc.) of each node physically connected to the OpenVisualizer.
• Displays errors reported by motes.
• can run with either physical motes, or emulated motes (for details, see OpenSim).

Installation

Prerequisites

Silicon Laboratories CP320x USB to UART Bridge (Driver Removal)
Silicon Laboratories CP320x VCP Drivers for Windows XP/2003 Server/Vista/7

* On Linux, TUN/TAP already is included with the operating system, and OpenVisualizer configures it on the fly. See our TUN/TAP in Linux page for more information.

The --trace option provides internal memory profiling of OpenVisualizer itself, and requires yappi.

Running it

The OpenVisualizer consists of core modules, and several types of user interfaces:

• a graphical user interface (GUI)
• a command-line interface (CLI)
• a web interface

You can use whichever user interface suits you best. The choice of user interface does not impact the function of the core module.

You start the OpenVisualizer in several ways:

• by invoking the Python script directly (or double-clicking on it)
• by using SCons

graphical user interface (GUI)

starting

You have two options to start it:

• double-click on openwsn-sw/software/openvisualizer/bin/openVisualizerApp/openVisualizerGui.py

• enter the following command from openwsn-sw/software/openvisualizer/:

  scons rungui

usage

The "motes" top menu lists all the motes connected to the OpenVisualizer (either physically over a serial port, or as emulated motes):

From the "motes" top menu, select the mote to be used as a DAG root and the "toggle" button. The other motes will now synchronize to it and form a DAG.

starting

You have two options to start it:

Code Organization

Modules

• openVisualizerGui.py is the master module. It can be run against real or simulated motes (see OpenSim). It lists all the connected motes and, for each, spawns a different execution thread.
• moteProbe.py contains the code which is executed by each thread. Whenever data is received from the mote, it is passed along to Parser.py.
• Parser.py dispatches all the data it receives to respective parser module. In case a frame of Status/Error/ErrorCritical is received from the serial port, ParserInfoErrorCritical.py calls the corresponding display* function from moteState.py.
• openVisualizerGui.py handles everything which is related to the graphical user interface. It is solely based on TkInter, the graphical interface which ships by default with Python. A single semaphore is used to arbitrate the access to the graphic elements.
• StackDefines.py is used by ParserInfoErrorCritical.py to translate error and status code into human-readable text.
