| | We provide support for the C language 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. |
| | |
| | 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 GCC as the simplest path to getting your code running. |
| | |
| | Once you have set up your development environment to run with Phidgets, we recommend you follow our guide on [[Phidget Programming Basics]]. The guide will showcase the fundamentals of programming with Phidgets, with examples in C. |

| == Getting started with C ==
| |
| Welcome to using Phidgets with C! By using C, you will have access to the complete Phidget22 API, including events. Example code is also provided for each Phidget channel class.
| |
|
| |
| If developing for Windows, keep reading; otherwise, select an operating system:
| |
| *[[#macOS | macOS]]
| |
| *[[#Linux | Linux]]

| ===Visual Studio===
| |
| ====Use our examples====
| |
| One of the best ways to start programming with Phidgets is to use our example code as a guide. In order to run the examples, you will need to download and install [https://www.visualstudio.com/ Microsoft Visual Studio].
| |
|
| |
|
| |
| Now that you have Microsoft Visual Studio installed, select an example that will work with your Phidget:
| |
| *{{SampleCode|C|C Examples}}
| |
|
| |
|
| |
| Open the example project and start the example by pressing the ''Local Windows Debugger'' button:
| |
|
| |
|
| |
| [[Image: c_vs_run.png|link=|center]]
| |
|
| |
|
| |
| The application will open the Phidget, list basic information about the Phidget, and demonstrate the Phidget's functionality. Here is an example of an Accelerometer channel on a Spatial Phidget:
| |
|
| |
|
| |
| [[Image: c_vs_output.PNG|link=|center]]
| |
|
| |
|
| |
| You should now have the example up and running for your device. Play around with the device and experiment with some of the functionality. When you are ready, the next step is configuring your project and writing your own code!
| |
|
| |
| ====Configure your project====
| |
| When you are building a project from scratch, or adding Phidget functionality to an existing project, you'll need to configure your development environment to properly link the Phidget C library. To begin:
| |
|
| |
|
| |
| Create a new Win32 Console application:
| |
|
| |
| [[Image:C_vs_newproject.PNG|link=|center]]
| |
|
| |
|
| |
| Select an empty project and finish:
| |
|
| |
| [[Image:C_vs_emptyproject.PNG|link=|center]]
| |
|
| |
|
| |
| If you are using a 64-bit machine, select x64, otherwise, keep x86:
| |
|
| |
| [[Image:C_vs_configuration.png|link=|center]]
| |
|
| |
|
| |
| Next, add a new item to your source folder:
| |
|
| |
| [[Image:C_vs_additem.png|link=|center]]
| |
|
| |
|
| |
| Give the source file a descriptive name and continue:
| |
|
| |
| [[Image:C_vs_addsource.PNG|link=|center]]
| |
|
| |
|
| |
| Access the project's properties:
| |
|
| |
| [[Image:C_vs_propertie.png|link=|center]]
| |
|
| |
|
| |
| Next, navigate to Configuration Properties -> C/C++ -> General and add the following line to the additional include directories:
| |
| *C:\Program Files\Phidgets\Phidget22
| |
|
| |
|
| |
| [[Image:C_vs_additionalinclude.png|link=|center]]
| |
|
| |
|
| |
| Navigate to Configuration Properties -> Linker -> Input and add the following line to the additional dependencies:
| |
| *C:\Program Files\Phidgets\Phidget22\phidget22.lib
| |
|
| |
|
| |
| [[Image:C_vs_additionadepend.png|link=|center]]
| |
|
| |
| Finally, include the Phidget library in your code, and any other header files:
| |
|
| |
| <syntaxhighlight lang='C'>
| |
| #include <phidget22.h>
| |
| </syntaxhighlight>
| |
|
| |
| [[Image:C_vs_finished.PNG|link=|center]]
| |
|
| |
|
| |
| Success! The project now has access to Phidgets. Next, view the [[#Write Code | write your own code]] section located below.
| |
|
| |
| ===GCC===
| |
| ====Cygwin/MinGW====
| |
| =====Use our examples=====
| |
| One of the best ways to start programming with Phidgets is to use our example code as a guide. In order to run the examples, you will need to download and install either [http://www.mingw.org/ MinGW] or [https://www.cygwin.com/ Cygwin].
| |
|
| |
|
| |
| Now that you have either MinGW or Cygwin installed, select an example that will work with your Phidget:
| |
| *{{SampleCode|C|C Examples}}
| |
|
| |
|
| |
| If you are using Cygwin, navigate to the folder where the example is and open the command prompt. Enter the following command to compile the example:
| |
| <syntaxhighlight lang='bash'>
| |
| gcc example.c -o example -I"/cygdrive/c/Program Files/Phidgets/Phidget22" -L"/cygdrive/c/Program Files/Phidgets/Phidget22/x86" -lphidget22
| |
| </syntaxhighlight>
| |
|
| |
|
| |
| If you are using MinGW, navigate to the folder where the example is and open the command prompt. Enter the following command to compile the example:
| |
| <syntaxhighlight lang='bash'>
| |
| gcc example.c -o example -I"C:/Program Files/Phidgets/Phidget22" -L"C:/Program Files/Phidgets/Phidget22/x86" -lphidget22
| |
| </syntaxhighlight>
| |
|
| |
| After running the commands above for either Cygwin or MinGW, an executable file called ''example.exe'' will be created. Enter the following command to run the example:
| |
| <syntaxhighlight lang='bash'>
| |
| example.exe
| |
| </syntaxhighlight>
| |
|
| |
|
| |
| You should now have the example up and running. When you are ready, the next step is configuring your project and writing your own code!

| |
| </syntaxhighlight>
| |
|
| |
| You can now compile the file as shown in the previous section.

|
| |
| ===Code::Blocks===
| |
| ====Use our examples====
| |
| One of the best ways to start programming with Phidgets is to use our example code as a guide. In order to run the examples, you will need to download and install [http://www.codeblocks.org/downloads Code::Blocks].
| |

| |
|
| |
| Now that you have Code::Blocks installed, select an example that will work with your Phidget:
| |
| *{{SampleCode|C|C Examples}}
| |
|
| |
|
| |
| Open the example in Code::Blocks (you do not need to create a new project) and navigate to Settings -> Compiler... as shown in the image below:
| |
|
| |
| [[Image:C_codeblocks_settings.png|link=|center]]
| |
|
| |
|
| |
| From the Global compiler settings screen, navigate to Search directories -> Compiler and add the following directory:
| |
| *C:\Program Files\Phidgets\Phidget22
| |
|
| |
| [[Image:C_codeblocks_compiler.PNG|link=|center]]
| |
|
| |
|
| |
| Next, select Search directories -> Linker and add the following directory:
| |
| *C:\Program Files\Phidgets\Phidget22\x86
| |
|
| |
| [[Image:C_codeblocks_linker.PNG|link=|center]]
