__NOTOC__


__TOC__
We provide support for Python in all major operating systems. We also provide instructions on how to get your project started in a number of common development environments. Select your operating system and preferred development environment below, and follow the instructions to get your project running with Phidgets.


==Introduction==
If you do not know which development environment you want to use, or your development environment of choice is not listed, we recommend starting with command line or terminal as the simplest path to getting your code running.

===Libraries===
 
{{AllQuickDownloads}}
===Description of Library===
C# programs on Windows depend on the following files, which the installers above put onto your system:
* <b>{{Code|phidget21.dll}}</b> contains the actual Phidgets library, which is used at run-time.  By default, it is placed in {{Code|C:\Windows\System32}}.
You will also need one of the following two files, depending on the .NET framework version you are targeting:
* <b>{{Code|Phidgets Python Module}}</b> is the Phidgets library for Python <i><b>2.5</b></i> or higher. Your compiler has to know where this file is.
 
If you do not want to use our installer, you can download the five [http://www.phidgets.com/downloads/libraries/Phidget21-windevel_2.1.8.20111220.zip file files].
 
 
Running the examples and writing your own code can be fairly compiler-specific, so we include instructions for each compiler below.
 
===IDLE===
 
=====Use Our Examples=====
 
Please start by downloading the [http://www.phidgets.com/downloads/examples/Python_2.1.8.20120131.zip examples] and unpack them into a foler.  While these examples were written in Python 3.0, they are also compatible with Python and 2.5 and 2.6.
 
If you aren't sure what the software example for your device is called, check the software object listed in the [[Device List | Getting Started guide for your device]].
 
The only thing left to do is to run the examples! Click on Debug &rarr; Start Debugging. Please note that the projects, by default try to find the {{Code|Phidget21.NET.dll}} in the {{Code|C:\Program Files\Phidgets}}. If you have it installed in another location, please change the path to the file's location accordingly. If you are receiving an error message regarding that the namespace Phidgets cannot be found, please re-add the reference to {{Code|Phidget21.NET.dll}}. Please see the [[#Write Your Own Code | Write Your Own Code ]] section for details.
 
[[File:CSharp VS2005 Run.PNG|link=|alt=Run‎]]
 
Once you have the C# examples running, we have a [[#Follow The Examples|teaching]] section below to help you follow them.
 
=====Write Your Own Code=====
 
When you are building a project from scratch, or adding Phidget function calls to an existing project, you'll need to configure your environment to properly link the Phidget C# libraries. To begin:
 
1. Generate a new Visual C# Windows Applications project with a descriptive name such as PhidgetTest.
 
[[File:CSharp VS2005 New Project.PNG|link=|alt=New Project]]
 
2. Add a reference to the .NET Phidgets library.
 
[[File:CSharp VS2005 Add Reference.PNG|link=|alt=Add Reference]]
 
3. Under the .NET tab, select {{Code|Phidget21.NET.dll}}.
If you used our installer, these files are installed in {{Code|C:\Program Files\Phidgets}}, by default. If it does not appear in this list, then you can browse to the Phidget Framework installation directory and add the file.
 
[[File:CSharp VS2005 Add Reference 2.PNG|link=|alt=Add Reference]]
 
4. Then, in your code, you will need to include the Phidget library:
 
<div class="source">
<syntaxhighlight lang=csharp>
  using Phidgets;
  using Phidgets.Events;
</syntaxhighlight>
</div>
 
 
The project now has access to the Phidget21 function calls and you are ready to begin coding.
 
The same [[#Follow The Examples|teaching ]] section which describes the examples also has further resources for programming your Phidget.
 
===Visual Studio 2003===
 
=====Use Our Examples=====
 
1. Download the [http://www.phidgets.com/downloads/examples/CSharp_2.1.8.20110615.zip examples] and unpack them into a folder. Here, you can find example programs for all the devices. If you are not sure what the software example for your device is called, check the software object listed in the [[Device List | Getting Started guide for your device]]. As the examples were written in newer versions of Visual Studio, Visual Studio 2003 is not able to open the examples. Fortunately, you can import the simple examples to a Visual Studio 2003 project. It will be difficult to import the full examples as you will need to recreate the GUI components. In the [[#Use Our Examples 2 | Use Our Examples]] section, it will be assumed that the simple examples are used. You will need this example source code to be copied into your C# project later on.
 
2. Next, a new project will need to be created. Generate a new Visual C# console application project with a descriptive name such as PhidgetTest.
 
[[File:CSharp_VS2003 New Project.PNG|link=|alt=New Project]]
 
3. Add a reference to the .NET Phidgets library.
 
[[File:CSharp_VS2003 Add Reference 1.PNG|link=|alt=Add Reference]]
 
4. Under the .NET tab, select {{Code|Phidget21.NET1.1.dll}}. If you used our installer, by default, this file is placed in {{Code|C:\Program Files\Phidgets}}. If it is in another location, please change the path to the file's location accordingly.
 
[[File:CSharp_VS2003 Add Reference 2.PNG|link=|alt=Add Reference]]
 
5. To import the simple example program into your project, please: open up {{Code|Class1.cs}}.
 
6. Traverse to the example in Windows Explorer and locate the {{Code|Program.cs}} file.
 
[[File:CSharp VS2003 Source Code.PNG|link=|alt=Source Code]]
 
7. Copy and paste the contents from that file into {{Code|Class1.cs}}.
 
8. Comment out the following line as it is not supported in .NET 1.1:
<div class="source">
<syntaxhighlight lang=csharp>
  using System.Collections.Generic;
</syntaxhighlight>
</div>
 
[[File:CSharp VS2003 Source Code 2.PNG|link=|alt=Source Code]]
 
9. Then, in your code, you will need to include the Phidget library:
<div class="source">
<syntaxhighlight lang=csharp>
  using Phidgets;
  using Phidgets.Events;
</syntaxhighlight>
</div>
 
10. Now, you can run the example. Click on Debug &rarr; Start.
 
[[File:CSharp VS2003 Run.PNG|link=|alt=Run]]
 
Once you have the C# examples running, we have a [[#Follow The Examples|teaching ]] section below to help you follow them.
 
=====Write Your Own Code=====
 
When you are building a project from scratch, or adding Phidget function calls to an existing project, you'll need to configure your development environment to properly link the Phidget C# libraries. Please see the [[#Use Our Examples 2 | Use Our Examples ]] section for instructions.
 
===Mono===
 
This section will provide instructions on how to compile using the {{Code|mcs}} compiler. Other compilers such as {{Code|gmcs}}, {{Code|smcs}}, and {{Code|dmcs}} all work in the same way. Start by downloading the C# Examples.
 
=====Use Our Examples=====
 
Download the [http://www.phidgets.com/downloads/examples/CSharp_2.1.8.20110615.zip examples] and unpack them into a folder. Here, you can find example programs for all the devices. If you aren't sure what the software example for your device is called, check the software object listed in the [[Device List | Getting Started guide for your device]]. Please only use the simple examples. The full examples uses Windows Forms, which Mono and the Gtk# toolkit are not completely compatible with. Locate the {{Code|Program.cs}} file as this contains the example source code. Copy the file into your working directory, and rename it to {{Code|example.cs}}.
<br/>
 
To compile and build an executable, run:
<div class="source">
<syntaxhighlight lang=bash>
mcs /out:example.exe /lib:"C:\Program Files\Phidgets" /r:phidget21.NET.dll example.cs
</syntaxhighlight>
</div>
 
If you have the {{Code|Phidget21.NET.dll}} installed in another location, please change the path to the file's location accordingly.
 
Afterwards, you will have an executable named {{Code|example.exe}} that you can run. Place the {{Code|Phidget21.NET.dll}} in the same directory as the executable and type the following to run the program:
<div class="source">
<syntaxhighlight lang=bash>
mono example.exe
</syntaxhighlight>
</div>
 
Once you have the C# examples running, we have a [[#Follow The Examples|teaching]] section below to help you follow them.
 
=====Write Your Own Code=====
 
When you are building a project from scratch, or adding Phidget function calls to an existing project, you'll need to configure your development environment to properly link the Phidget C# libraries. Please see the [[#Use Our Examples 3 | Use Our Example ]] section for instructions.
 
In your code, you will need to include the Phidget library:
 
<div class="source">
<syntaxhighlight lang=csharp>
  using Phidgets;
  using Phidgets.Events;
</syntaxhighlight>
</div>
 
 
The project now has access to the Phidget21 function calls and you are ready to begin coding.
 
The same [[#Follow The Examples|teaching]] section which describes the examples also has further resources for programming your Phidget.
 
===MonoDevelop===
 
=====Use Our Examples=====
 
Download the [http://www.phidgets.com/downloads/examples/CSharp_2.1.8.20110615.zip examples] and unpack them into a folder. Here, you can find example programs for all the devices. These examples were written in Visual Studio 2005 and 2008, but are also compatible with MonoDevelop.
 
To load all projects in MonoDevelop, go to File &rarr; Open, and open {{Code|AllExamples/AllExamples.sln}}
 
This will load all of the examples available for C#, and then you can set your main project to be the one that matches your device.  If you aren't sure what the software example for your device is called, check the software object listed in the [[Device List | Getting Started guide for your device]]. If you are running under the .NET framework, you can use either the full or simple examples. Otherwise, if you are running under the Mono framework, please only use the simple examples. The full examples uses Windows Forms, which is not completely compatible with Mono's Gtk#.
 
[[File:CSharp MonoDevelop Win Start Up.PNG|link=|alt=Start Up Project]]
 
The only thing left to do is to run the examples! Right click the project, and click on {{Code|Run With}} and select the target framework. Please note that the projects, by default try to find the {{Code|Phidget21.NET.dll}} in the {{Code|C\Program Files\Phidgets}}. If you have it installed in another location, please change the path to the file's location accordingly. If you are receiving an error message regarding that the namespace Phidgets cannot be found, please re-add the reference to {{Code|Phidget21.NET.dll}}.

=====Write Your Own Code=====
 
When you are building a project from scratch, or adding Phidget function calls to an existing project, you'll need to configure your  development environment to properly link the Phidget C# libraries. To begin:
 
1. Create a new C# empty project with a descriptive name such as PhidgetTest.
 
[[File:CSharp MonoDevelop Win New Project.PNG|link=|alt=New Project]]
 
2. Add a reference to the .NET library.
 
[[File:CSharp MonoDevelop Win Reference.PNG|link=|alt=Add Reference]]
 
3. Select {{Code|Phidget21.NET.dll}}. If you used our installer, by default, this file is placed in {{Code|C:\Program Files\Phidgets}}. If it is in another location, please change the path to the file's location accordingly.
 
[[File:CSharp MonoDevelop Win Reference 2.PNG|link=|alt=Add Reference]]
 
4. Then, in your code, you will need to include the Phidget library:

==Linux==
 
Python has support on Linux. 
 
The first step in using Python on Linux is to install the Phidget libraries.  Compile and install them as explained on the main [[OS - Linux | Linux page]].  That Linux page also describes the different Phidget files, their installed locations, and their roles.
 
==Follow The Examples==
 
By following the instructions for your operating system and compiler above, you probably now have a working example and want to understand it better so you can change it to do what you want.  This teaching section has resources for you to learn from the examples and write your own.
 
Next, comes our API information.  These resources outline the Python Phidget functions:

===Example Flow===
 
{{ExamplePseudocode|In Python, you can name these '''event''' functions whatever you like.  You will then pass them as function pointers to the Phidget library below in the Main Code section.  This hooks them into the actual events when they occur. <br>
In the example code, the event functions common to all Phidgets are called things like '''AttachHandler()''' and '''DetachHandler()''', etc.<br><br>
Some event functions will be specific to each device, like when a tag is read on an RFID board, or when a sensor value changes on an Interface Kit.
Other functions are given in the examples to show you more detail on using your Phidget.  For example, '''DeviceInitialize()''' will show what needs to be set up for your Phidget before using it.
|Creating a Phidget software object in Python is specific to the Phidget.  For a Phidget Spatial, for example, this would involve creating a {{Code|Spatial}} object.  The examples show how to do this and other API functions.<br><br>
The object provides device specific methods and properties which are available from the API for your specific Phidget.|
