Portal’s Extended Capabilities
Built-in Functionality
One of the key elements of a sensor network is being able to log and/or display the
gathered information.
Portal has several built-in ways to track and/or display data. Let’s use the sensors we just
installed on the Proto Board in another example.
Demonstration 4: The Many-Meter
If you are interested in the types of things SNAP Engines can do, you have probably
heard of a multi-meter. Let’s put together a many-meter. The good news is that we
already have all the components we will need wired up and ready to rock.
GOAL: To show how information can be communicated back to the Portal PC for display
and logging.
Step 1 – Switch to the Node View pane in Portal and select the node associated with the
Proto Board.
Upload the “Many-Meter.py” SNAPpy script onto the Proto Board (a skill we’ve
mastered from previous sections, but here is a hint:
Let’s give the Proto Board a name. Click on the
).
Change Configuration icon from the
toolbar and then select the Device tab. Change the Device Name (currently blank) to read
“OurDemo”. Click “OK”.
Step 2 – Switch back to the Node View pane and select the node associated with the
SNAPstick.
Switch to the Node Info pane and Erase the script currently running on the SNAPstick by
clicking on the
icon located in the toolbar.
Select the New Configuration… option from the Network pull-down menu in Portal. This
will reset your view to use our new name. The SNAPstick without a script will now have
a node name like “node1” or “node2”. (This assumes you have not changed any Portal
preferences from the defaults with which Portal was installed. If you are working with an
existing Portal installation where someone may have adjusted the Portal preferences, it
may be necessary to click the Broadcast Ping icon in the Portal toolbar to make the
nodes reappear.)
