Introduction
Overview
The PhidgetSBC is a fully functional Single Board Computer
with an integrated PhidgetInterfaceKit 8/8/8. At its most
basic, it can be thought of as a Phidget that you connect
using a network cable instead of directly to the USB. The
PhidgetSBC also provides four USB full-speed ports that allow
you to use normal USB Phidgets over its network connection.
This can extend the effective range of a Phidget from USB’s
maximum of 15 feet, to anywhere that your network reaches.
The PhidgetSBC exposes an easy to use interface for setting
up and running custom applications on-board, written in
either Java or C. This allows the PhidgetSBC to operate
autonomously, without the need for a graphical interface or a
remote connection at all times.
For more advanced users, the PhidgetSBC is an embedded
computer that runs a custom Linux Distro, built using Buildroot. We provide full shell access via a built-in SSH server,
full GCC and development tools, the GDB debugger, and all of the standard command line tools expected on a
modern Linux system. This allows for on-board development in C, and full access to the system for customizing.
An integrated PhidgetInterfaceKit 8/8/8 allows you to connect devices to any of 8 analog inputs, 8 digital inputs and
8 digital outputs. It provides a generic, convenient way to interface your PC and PhidgetSBC with a wide variety of
devices and it operates exactly the same way as an external PhidgetInterfaceKit.

Programming Environment
Operating System: Custom Linux Distro, built using Buildroot
Programming Languages (APIs): C/C++, Java
Examples: Many example applications for all the operating systems and development environments above are
available for download at www.phidgets.com.
Note: AninternetbrowserisrequiredtousethecongurationGUI.
When controlling the PhidgetSBC remotely, you can use any Phidgets supported operating systems and languages:
Operating Systems: Windows 2000/XP/Vista, Windows CE, Linux, and Mac OS X
Programming Languages (APIs): VB6, VB.NET, C#.NET, C++, Flash 9, Flex, Java, LabVIEW, Python, Max/MSP,
and Cocoa.
Analog inputs
They are used to measure continuous quantities, such as temperature, humidity, position, pressure, etc. Phidgets
offers a wide variety of sensors that can be plugged directly into the board using the cable included with the sensor.
Here is a partial list of sensors currently available:
IRDistanceSensor IRReectiveSensor VibrationSensor LightSensor
Force Sensor Humidity Sensor Temperature Sensor Magnetic Sensor
Rotation Sensor Voltage Divider Touch Sensor Motion Sensor
Mini Joy-Stick Pressure Sensor Voltage Sensor Current Sensor
Slide Sensor
Digital Inputs
Digital Inputs can be used to convey the state of push buttons, limit switches, relays, logic levels, etc...
Digital Outputs
Digital Outputs can be used to drive LEDs, solid state relays (have a look at our SSR board), transistors; in fact,
anything that will accept a CMOS signal.
Digital outputs can be used to control devices that accept a +5V control signal.
With transistors and some electronics experience, other devices can be controlled, such as buzzers, lights, larger
LEDs, relays.

Basic Use
Basic use of the PhidgetSBC allows the opening of connected Phidgets over the network. Using another Phidget with
the PhidgetSBC in this way is almost exactly like using Phidgets over USB, in respect to the API calls and behavior.
However, some extra considerations need to be made when working with the PhidgetWebservice.
Phidget Webservice
Support for opening Phidgets over the network is made possible via the Phidget Webservice. This allows a user
to write an application in a system and language of their choosing and then operate Phidgets connected to the
PhidgetSBC. It is a socket based server that runs on the PhidgetSBC at all times (unless disabled), and allows any
attached Phidgets to be seen and opened directly over the network.
Opening and controlling a Phidget over the network is nearly the same as opening one locally. The main differences
are:
Different open calls that include server information. New calls OpenRemote and openRemoteIP (naming depends•
on language).
Access to Webservice based properties: Server hostname, port and ID.•
Access to server connect and disconnect events, and network error events.•
Phidgets can be opened by more then one separate application at the same time.•
Reliability is more of a issue because network connections are easily broken.•
Opening a Phidget over the network is asynchronous and pervasive, just like opening locally. This means that if a
connectiontotheremoteservercannotbeestablishedrightaway,itwillkeeptryingindenitely,andevensurvive
the server being stopped and started, etc.
Instances of the Phidget Webservice can be referred to either using hostname (IP Address) and port number, or by
Server ID. The advantage of using a Server ID is that it stays consistent compared to IP addresses, and you don’t
need to know the Port number. A Webservice Server ID is assigned when the Webservice is run - which on the
PhidgetSBC defaults to ‘phidgetsbc’. In order to use a Server ID, the Bonjour utility also needs to be installed.
Refer to the Programming Manual and the API manual for your language for more information about using the
Phidget Webservice.
Reliability
Determining reliability needs can become important while opening Phidgets over the network, because the network
connection can potentially be interrupted at any time. This can leave the network attached Phidget in an undesirable
state. For example - if a motor controller is driving a motor and the connection is lost, there is no way to stop the
motor until the connection is re-established. These issues are less important if you are just receiving sensor data
from an Interface Kit.
17
1070_0_Product_Manual - October 28, 2010 8:52 AM
It’s generally a good idea to catch server connect and disconnect and Phidget attach and detach events in order to
know the state of the connections. It’s also a good idea to catch error events - this is where network errors will be
reported.
If reliability is important, you should consider writing a program to run locally on the PhidgetSBC, and communicate
with it through the Dictionary interface. This way, if the connection is broken, the local application will notice and be
able to take any appropriate actions. See the advanced chapter for more information.
Finding Phidgets on the Network
AnyPhidgetsattachedtothePhidgetSBCcanbeidentiedusingtheStatus>>Phidgetspageintheconguration
interface, and should be seen on the network through the Webservice.
The Phidget Control Panel has a Bonjour tab (under WebService >> Bonjour) that lists all detected network attached
Phidgets. The Phidgets connected to the PhidgetSBC should be seen here and can be opened by double clicking its
name in the menu.
Network attached Phidgets can also be located programmatically with the Phidget Manager. The Phidget Manager
