==Data Flow==
Data and control flows up and down the USB connection:
[[Image:wiap-dataflow.jpg|700px|link=|alt=|center]]
== Software Channels ==
A Phidget device exports one or more channels.  Each device channel implements a channel class where that class defines the interface used to access the features of the device in a generic fashion.  For example, a Phidget device that supports sensing voltage exports a channel that implements the VoltageInput class.  The VoltageInput class defines the methods, properties, events and errors relevant to receiving voltage data.
[[Image:voltageInput_object.jpg|300px|link=|alt=|center]]
You can check the {{Phidget22API}} for details about channel classes. For example, the [{{SERVER}}/products.php?product_id=1018 1018] has five channels (with five distinct channel classes):
[[Image:1018_objects.jpg|600px|link=|alt=|center]]
Each Phidget channel class inherits common functionality from the base Phidget class.  The Phidget class defines methods like {{Code|open()}} and {{Code|close()}}, and properties like {{Code|DeviceSerialNumber}}.
To help understand the concepts above, we have included a simple C# program that can be used with the [{{SERVER}}/products.php?product_id=1018 1018].
<syntaxhighlight lang=csharp>
using Phidget22;
int main() {
    VoltageInput vin;            // A user channel of the class VoltageInput
    vin = new VoltageInput();    // Create an instance of the class   
    vin.Channel = 0;            // Specify the index of the device channel to attach to
    vin.Open(5000);              // Begin attempting to attach to the device channel
    System.Console.WriteLine("My channel 0 sensor reads " + vin.Voltage); // Get the voltage value
    vin.Close();                // Close the channel, which detached it from the device channel
}
</syntaxhighlight>

At Phidgets, our philosophy is that you don't have to be an electrical engineer in order to create sophisticated projects using motors, sensors and other electronics. You simply need to know how to code.


Phidgets are building-blocks for sensing and control using a computer, tablet, or phone. Phidgets enable your software application to interact with the physical world.

The advantage of using Phidgets is that all Phidgets can be plugged in and used in your project out of the box, without having to follow complex pinout diagrams or configure communication between the device and computer. With Phidgets, we deal with the details of getting the electronics behaving as they should, so you can focus on the programming and details of your final product.

Hardware Introduction

Phidgets connect via a USB port:


Some Phidgets are a complete, self-contained sensing package. An example is the 1042 , which measures motion:


Other Phidgets are a 'building block' to use other sensors. An example is the 1048 which allows the use of wire thermocouples:



Finally, a Phidget may be a VINT Hub, made up of versatile ports that can be used as inputs or outputs, and also connect to smart VINT devices.

Programming

For the most part, using Phidgets requires writing software. The Phidgets API is available in many different programming languages:

Core Languages Mobile Languages Other Languages
C Sharp C# Objective C Objective C LabVIEW LabVIEW
C/C++ C/C++ Swift Swift Max/MSP Max/MSP
Python Python Android Android Java
Java Java
Visual Basic .NET Visual Basic .NET
JavaScript JavaScript

The Phidget software libraries are supported on a number of operating systems:

Desktop OSes Mobile/Wireless OSes
OS - WindowsWindows OS - Phidget SBCPhidget SBC
OS - LinuxLinux OS - iOSiOS
OS - OS XOS X OS - AndroidAndroid

Network Server

Using the Phidgets API, applications on remote computers, phones, and Single Board Computers can attach to Phidget devices over the network as if they were local. This includes WWW based applications using the Phidget JavaScript library.

Further Reading

With the combination of events, modular sensors, and network support, your system can range from simple to incredibly complex.

We encourage customers to not only build projects for themselves, but also to design and build real-world products using Phidgets. Our libraries can be distributed with your code to your customers.
