Getting started with C#

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
Linux (including PhidgetSBC)

Windows(2000/XP/Vista/7)

Libraries

Description

C# programs on Windows depend on three files, which the installers above put onto your system:

phidget21.dll contains the actual Phidgets library, which is used at run-time. If you used our installer, it's already correctly placed in C:\Windows\System32. It can be manually installed - check our Manual Installation instructions.
Phidget21.NET.dll is used...
Phidget21.NET1.1.dll is used...

Running the examples and writing your own code can be fairly compiler-specific, so we include instructions for each compiler below.

Visual Studio

If you are using Visual Studio 2005/2008/2010, please start by downloading the C# Examples. These examples were written in Visual Studio 2005 and 2008, but Visual Studio 2010 will easily upgrade them.

Microsoft Visual C# Examples

If you are using Visual Studio 2003, please start by downloading the Generic C# examples.

Microsoft Visual C# Examples

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 Microsoft Visual Studio for more information.

Visual Studio 2005/2008/2010

Use Our Examples

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.

To run the examples, you first download them from above and unpack them into a folder. To load all projects in Visual Studio, go to File | Open | Project | Solution, and open Visual Studio Phidgets Examples.sln in the VCpp folder of the examples.

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 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 phidget21.h and phidget21.lib in the $(SystemDrive)\Program Files\Phidgets. If you have these files installed in another location, please change the path accordingly. Please see the next section for details.

Once you have the C/C++ examples running, we have a 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 compiler / development environment to properly link the Phidget C/C++ libraries. To begin:

Generate a new Visual C++: Win32 Console Application project with a descriptive name such as PhidgetTest.

Next, select Console Application

Open the project properties window.
Navigate to Configuration Properties | C/C++.
Add "C:\Program Files\Phidgets" to the additional directories field. This step will find the phidget21.h file in the corresponding directory. If the file is placed in another location, please adjust the path accordingly.

Navigate to Configuration Properties | Linker | Input.
Edit the additional dependencies and add "C:\Program Files\Phidgets\phidget21.lib". This step will find the phidget21.lib file in the corresponding directory. If the file is placed in another location, please adjust the path accordingly.

The project now has access to the Phidget21 function calls and you are ready to begin coding.

Then, in your code, you will need to include the Phidget library:

  #include <phidget21.h>

The same teaching section which describes the examples also has further resources for programming your Phidget.

Visual Studio 2003

Start by downloading the C# Examples. You can import the simple examples into a Visual Studio 2003 C# project.

Microsoft Visual C# Examples

Use Our Examples

Download the examples from above 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 Getting Started guide for your device. You will need this example source code to be copied into your C++ project later on.

Next, a new project will need to be created.

Generate a new Visual C++ empty project(.NET) with a descriptive name such as PhidgetTest.

To import the example program into your project, please:

Create a new C++ file by adding a new item to the source files folder.

An empty C++ file will pop up. Please copy and paste the contents of the example program into here.

Next, the project setting needs to be set up.

Open the project properties window.
Navigate to Configuration Properties | C/C++.
Add "C:\Program Files\Phidgets" to the additional include directories field. This step will find the phidget21.h file in the corresponding directory. If the file is placed in another location, please adjust the path accordingly.

Navigate to Configuration Properties | Linker | Input.
Add "C:\Program Files\Phidgets\phidget21.lib" to the additional dependencies field. This step will find the phidget21.lib file in the corresponding directory. If the file is placed in another location, please adjust the path accordingly.

The project now has access to the Phidget21 function calls and you are ready to begin coding.

Now, you can run the example. Click on Debug | Start Without Debugging.

Once you have the C/C++ examples running, we have a 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 compiler / development environment to properly link the Phidget C/C++ libraries. Please see the previous section for instructions.

Mono

Start by downloading the C# Examples.

Microsoft Visual C# Examples

Use Our Examples

Once you have the C/C++ examples running, we have a 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 compiler / development environment to properly link the Phidget C/C++ libraries. Please see the previous section for instructions.

MonoDevelop

Start by downloading the Generic C/C++ Examples. You can import these examples into a Dev C++ project.

Generic C/C++ Examples

Use Our Examples

Download the examples from above 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 Getting Started guide for your device. You will need this example source code to be copied into your Dev C++ project later on.

In order to control Phidgets with Dev C++, the phidget21.lib file will need to be converted to a format that Dev C++ accepts, as described in the following steps:

Download the reimp tool
Open up command line and traverse to the directory containing the reimp tool. Type the following command to create libphidget21.a

  reimp.exe "C:\Program Files\Phidgets\phidget21.lib"

The command above assumes that the phidget21.lib is in the corresponding directory. If the file is placed in another location, please adjust the path accordingly. Please note that the 64 bit version of phidget21.lib is not supported on Dev C/C++. Please use the 32 bit version of phidget21.lib.

Place libphidget21.a in <Dev-Cpp Install Directory>/lib.

Next, a new project will need to be created. The following steps are written under Dev-C++ 4.9.9.2.

Generate a new console application with a descriptive name such as PhidgetTest. Please select C as the project type.

Next, the project settings needs to be set up.

Navigate to Project Options | Directories | Include Directories.
Add a new path to C:\Program Files\Phidgets. This step will find the phidget21.h file in the corresponding directory. If the file is placed in another location, please adjust the path accordingly.

Navigate to Project Options | Parameters | Linker.
Add -lphidget21 to the field. This step will find the libphidget21.a file in <Dev-Cpp Install Directory>/lib.

The project now has access to the Phidget21 function calls and you are ready to begin coding.

To import the example program into your project, please:

Open up main.c in the editor.
An empty C file will pop up. Please copy and paste the contents of the example program here.

Now, you can run the example. Click on Execute | Compile & Run.

Once you have the C/C++ examples running, we have a 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 compiler / development environment to properly link the Phidget C/C++ libraries. Please see the previous section for instructions.

Mac OS X

C# has excellent support on Mac OS X through the gcc compiler.

The first step in using CC# 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.

Template:ContentNeeded

Use Our Examples

After installing the Phidget libraries for Linux as above, you're ready to run the examples:

Generic C/C++ Examples

To run the example code, you'll need to find the source code for your specific device. Then, compile the code under your platform and run it.

The examples assume that the compiled libraries have been set up properly. To set them up on Mac OS X, follow the Getting Started page for your specific device

To compile, link the Phidget libraries, and build an executable binary on Mac OS X, do (for example, depending on the Headers location):

  gcc example.c -o example -framework Phidget21 -I/Library/Frameworks/Phidget21.framework/Headers

After using gcc, you will have an executable named example that you can run.

Write Your Own Code

When writing your code from scratch, you must include a reference to the library header:

  #include <phidget21.h>

Then, you would compile your completed C/C++ code the same way as the examples above.

To learn how to write your own code for your Phidget, and to learn more about our API, we have a teaching section to help you follow the provided C/C++ examples. Even more help and references are provided from there.

Linux

C# has support on Linux through the gcc compiler.

The first step in using C/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.

Use Our Examples

After installing the Phidget libraries for Linux as above, you're ready to download and run the examples:

Generic C/C++ Examples

To run the example code, you'll need to download and unpack the examples, and then find the source code for your specific device. The source file is usually named similarly to your device. Then, compile the code under your platform and run it. When compiling, you need to link to the phidget21 library.

To compile, link the Phidget libraries and build a binary executable on Linux, do the following in a terminal in the directory with example.c:

  gcc example.c -o example -lphidget21

In this case, example.c would be the .c file specific to your device. After using gcc, you will have an executable named example that you can run.

On Linux, if you have not set up your udev rules for USB access, you will need to run the program as root:

     sudo ./example

Write Your Own Code

When writing your code from scratch, you start it as you would any C/C++ code on Linux, such as within a text editor like Emacs, Vi, Gedit, or Kate. In your .c source code file, you must include a reference to the library header:

  #include <phidget21.h>

Then, you would compile your completed C/C++ code the same way as the examples above.

To learn how to write your own code for your Phidget, and to learn more about our API, we have a teaching section to help you follow the provided C/C++ examples and which has resources such as the API reference.

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/C++ Phidget functions:

+===MonoDevelop===
+Start by downloading the Generic C/C++ Examples. You can import these examples into a Dev C++ project.
+*[http://www.phidgets.com/downloads/examples/phidget21-c-examples_2.1.8.20111028.tar.gz Generic C/C++ Examples]
+=====Use Our Examples=====
+Download the examples [[#Dev C++|from above]] 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]]. You will need this example source code to be copied into your Dev C++ project later on.
+<br/>
+In order to control Phidgets with Dev C++, the <code>phidget21.lib</code> file will need to be converted to a format that Dev C++ accepts, as described in the following steps:
+* Download the [http://www.phidgets.com reimp tool]
+* Open up command line and traverse to the directory containing the reimp tool. Type the following command to create <code>libphidget21.a</code>
 <div style="background-color: #f3f3f3; border-color: #1c9edb; border-width:1px; border-style: dashed;">
 <font size="3">
-<source lang=CSharp>
+<source lang=bash>
+  reimp.exe "C:\Program Files\Phidgets\phidget21.lib"

-{
-     ifKit = new InterfaceKit();
-     ifKit.open();
-     ifKit.waitForAttachment(3000);

-The different types of open can be used with parameters to try and get the first device it can find,
+The command above assumes that the <code>phidget21.lib</code> is in the corresponding directory. If the file is placed in another location, please adjust the path accordingly. Please note that the 64 bit version of <code>phidget21.lib</code> is not supported on Dev C/C++. Please use the 32 bit version of <code>phidget21.lib</code>.

-Phidgets, a local connection will reserve the device until closed. This prevents any other instances
-from retrieving data from the Phidget, including other programs. The one connection per device limit
-does not apply when exclusively using the Phidget Webservice.
-===Event Driven Programming===
+Next, a new project will need to be created. The following steps are written under Dev-C++ 4.9.9.2.
+* Generate a new console application with a descriptive name such as PhidgetTest. Please select C as the project type.
+<br/>[[File:DevC New Project.PNG]]<br/><br/>
+Next, the project settings needs to be set up.
+* Navigate to Project Options | Directories | Include Directories.
+* Add a new path to <code>C:\Program Files\Phidgets</code>. This step will find the <code>phidget21.h</code> file in the corresponding directory. If the file is placed in another location, please adjust the path accordingly.
+<br/>[[File:DevC Header.PNG]]<br/><br/>
+* Navigate to Project Options | Parameters | Linker.
+* Add <code>-lphidget21</code> to the field. This step will find the <code>libphidget21.a</code> file in <code><Dev-Cpp Install Directory>/lib</code>.
+<br/>[[File:DevC Library.PNG]]<br/><br/>
+The project now has access to the Phidget21 function calls and you are ready to begin coding.
+To import the example program into your project, please:
+* Open up <code>main.c</code> in the editor.
+* An empty C file will pop up. Please copy and paste the contents of the example program here.

+==Mac OS X==
+C# has excellent support on Mac OS X through the gcc compiler.
+The first step in using CC# on Mac is to install the Phidget libraries.  Compile and install them as explained on the [[Device List|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.
+{{ContentNeeded|The information we say that we say on the OS - Mac OS X page (i.e. the different files, locations, and roles) should actually be added there}}
+===Use Our Examples===
+After installing the Phidget libraries for Linux as above, you're ready to run the examples:
+*[http://www.phidgets.com/downloads/examples/phidget21-c-examples_2.1.8.20111028.tar.gz Generic C/C++ Examples]
+To run the example code, you'll need to find the source code ''for your specific device''.  Then, compile the code under your platform and run it.
+The examples assume that the compiled libraries have been set up properly.  To set them up on Mac OS X, follow the ''Getting Started'' page for [[Device List | your specific device]]
+To compile, link the Phidget libraries, and build an executable binary on Mac OS X, do (for example, depending on the Headers location):
-We recommend the use of event driven programming when working with Phidgets. In C# we can
-hook an event handler at loading with the following code:
 <div style="background-color: #f3f3f3; border-color: #1c9edb; border-width:1px; border-style: dashed;">
 <font size="3">
-<source lang=CSharp>
+<source lang=bash>
+  gcc example.c -o example -framework Phidget21 -I/Library/Frameworks/Phidget21.framework/Headers
+</source>
+</font>
+</div>
+After using gcc, you will have an executable named <code>example</code> that you can run.
+===Write Your Own Code===
+When writing your code from scratch, you must include a reference to the library header:
+<div style="background-color: #f3f3f3; border-color: #1c9edb; border-width:1px; border-style: dashed;">
+<font size="3">
+<source lang=cpp>
+  #include <phidget21.h>
+</source>
+</font>
+</div>
+Then, you would compile your completed C/C++ code the same way as the examples above.

-ifKit.SensorChange += new SensorChangeEventHandler(ifKit_SensorChange);
+C# has support on Linux through the gcc compiler.
+The first step in using C/C++ 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.
+===Use Our Examples===

+*[http://www.phidgets.com/downloads/examples/phidget21-c-examples_2.1.8.20111028.tar.gz Generic C/C++ Examples]
+To run the example code, you'll need to download and unpack the examples, and then find the source code ''for your specific device''.  The source file is usually named similarly to your device.  Then, compile the code under your platform and run it.  When compiling, you need to link to the phidget21 library.
+To compile, link the Phidget libraries and build a binary executable on Linux, do the following in a terminal in the directory with <code>example.c</code>:
+<div style="background-color: #f3f3f3; border-color: #1c9edb; border-width:1px; border-style: dashed;">

-to the API manual for a full list of events and their usage.
-At the end of your program, unhook any events and call Application.DoEvents(). This will make sure
-there are no outstanding events being processed before calling close.

-Working directly with the Phidget
-Some values can be read and sent directly to the Phidget, simply use the instance members and
-properties. This is also how you would set properties on the Phidget such as the output state or
-sensor sensitivity. These functions can be used inside a polling loop as an alternative to event driven
-programming.
-int val = ifKit.sensors[0].Value;
-===Working with multiple Phidgets===
+Then, you would compile your completed C/C++ code the same way as the examples above.
+To learn how to write your own code for your Phidget, and to learn more about our API, we have a [[#Follow The Examples|teaching section]] to help you follow the provided C/C++ examples and which has resources such as the API reference.
+==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/C++ Phidget functions:
-Multiple Phidgets of the same type can easily be run inside the same program. In our case, it
+{{UsingAPhidgetInCodeGeneral|both of which are available in C/C++|[http://www.phidgets.com/documentation/Phidget21_C_Doc.zip C/C++ API]}}
-requires another PhidgetInterfaceKit instance to be defined and initialized. The new instance can then
-be set up, opened and used in the same process as the previous one.
-If the application needs to distinguish between the devices, open can be called with the serial
-number of a specific Phidget.
-===Other Phidgets===
+===Example Flow===
-The design given in this document can also be followed for almost all Phidgets. For example, if
+{{ExamplePseudocode|In C/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. <br>

+In the example code, the event functions common to all Phidgets are called things like '''AttachHandler()''' and '''DetachHandler()''', etc.<br><br>
-instead of an InterfaceKit. The methods and events available would change but they can be accessed
+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.
-in a similar manner.
+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 C is specific to the Phidget.  For a Phidget Spatial, for example, this would involve creating an object with the <code>CPhidgetSpatialHandle</code> type, and then initializing it using the <code>CPhidgetSpatial_create</code> function.  The examples show how to do this and other API functions.<br><br>
+Other C calls follow a similar syntax - <code>CPhidgetXXX_function</code>, where XXX is the name of your device, and function is an action available from the API for your specific Phidget.|
