| ===Description of Library Files===
| |
| 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|/lib}}</b> is the Phidgets library for .NET framework <i><b>2.0</b></i> or higher. Your compiler has to know where this file is. By default, it is placed into {{Code|C:\Program Files\Phidgets}}. You can either point your compiler to that location, or copy and link to it in a directory for your project workspace.
| |
| * <b>{{Code|examples}}</b> is the Phidgets library for .NET framework <i><b>1.1</b></i>. Your compiler has to know where this file is. By default, is is placed into {{Code|C:\Program Files\Phidgets}}. You can either point your compiler to that location, or copy and link to it in a directory for your project workspace.
| |
|
| |
| 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.
| |
|
| |
| ===Visual Studio 2005/2008/2010===
| |
|
| |
| Microsoft makes free versions of Visual Studio available known as Express Editions. The Express editions are suitable for most applications, but are limited in features for more complex applications. Please see [http://www.microsoft.com/visualstudio Microsoft Visual Studio] for more information.
| |
|
| |
| =====Use Our Examples=====
| |
|
| |
| Please start by downloading the [http://www.phidgets.com/downloads/examples/CSharp_2.1.8.20110615.zip examples] and unpack them into a foler. While these examples were written in Visual Studio 2005 and 2008, Visual Studio 2010 will easily open and upgrade them. To load all projects in Visual Studio, go to File → Open → Project, and open {{Code|AllExamples/AllExamples.sln}} or {{Code|AllExamples/AllExamples_vs2008.sln}} for Visual Studio 2005 and 2008, respectively.
| |
|
| |
| If you are opening the Phidget examples in Visual Studio 2010, you will need to go through the Visual Studio Conversion Wizard to convert the 2005 or 2008 project.
| |
| [[File:VS2005 Conversion Wizard.PNG|link=|alt=Conversion Wizard]]
| |
|
| |
| 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]].
| |
|
| |
| The only thing left to do is to run the examples! Click on Debug → 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.

Ruby is an interpreted and object oriented scripting language with simple syntax created by Yukihiro Matsumoto.
Introduction
If this is your first time working with a Phidget, we suggest starting with the Getting Started page for your specific device. This can be found in the user guide for your device. That page will walk you through installing drivers and libraries for your operating system, and will then bring you back here to use Ruby specifically.
Ruby is capable of using the complete Phidget API, including events. We also provide example code in Ruby for all Phidget devices.
Ruby can be developed with Linux and Mac OS X.
You can compare Ruby with our other supported languages.

Getting started with Ruby
If you are new to writing code for Phidgets, we recommend starting by running, then modifying existing examples. This will allow you to:
- Make sure your libraries are properly linked
- Go from source code to a test application as quickly as possible
- Ensure your Phidget is hooked up properly
Instructions are divided up by operating system. Choose:
Windows(2000/XP/Vista/7)
Mac OS X
C# has excellent support on Mac OS X through the Mono framework.
The first step in using C# on Mac is to install the Phidget libraries. Compile and install them as explained on the getting started guide for your device. Then, the OS - Mac OS X page also describes the different Phidget files, their installed locations, and their roles....
Linux
C# has support on Linux through the Mono framework.
The first step in using C# on Linux is to install the Phidget libraries. Compile and install them as explained on the main 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 C# Phidget functions:
- C# API (This is the complete set of functions you have available for all Phidgets)
- Device Specific APIs - The one for your Phidget can be found in its user guide.
To learn the details behind opening, configuring, using, and closing your Phidget, try the General Phidget Programming page. That page also describes using the Phidget in an event-driven manner and in a traditional manner, both of which are available in C#.
Example Flow
The Hello World example has this general structure so you can follow along. We also have an in-depth general introduction to writing Phidget code (like open, read data, etc), as well as the
C# API for specific syntax:
|
// ----- Event and Other Functions -----
Create any Language-Specific Functions (exception handling)
Create General Attach, Detach, and Error Handling Functions:
- On attach: Print Hello Message
- On detach: Print Goodbye Message
|
|
In C#, 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.
In the example code, the event functions common to all Phidgets are called things like AttachHandler() and DetachHandler(), etc.
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.
|
|
// ----- Main Code -----
Create Manager Software Object
Hook Event Functions created above to Device
Open Device
- Wait for 'Enter' key character input
- Handle on-going attach and detach events
- Print Hello and Goodbye messages
- Exit upon input
Close Device
Delete Device
|
|
Creating a Phidget software object in C# is specific to the Phidget. For a Phidget Spatial, for example, this would involve creating a Spatial object. The examples show how to do this and other API functions.
The object provides device specific methods and properties which are available from the API for your specific Phidget.
