| C/C++ has a complete API and sample code for all Phidgets devices. <br> | | __NOTOC__ |
| For a complete list of our supported languages and their support status, [[Levels of Support|click here]].
| | [[Category:Language]] |
| | 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. |
|
| |
|
| C/C++ can be developed with various Windows compilers, Mac OSX, and Linux.
| | 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. |
|
| |
|
| ==Development Environments and Compilers==
| | 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. |
|
| |
|
| Describe each major compiler and notable differences or important information. (eg. framework versions) If there are known issues/workarounds mention them and link to the corresponding issue at the bottom of the page.

|
| ==Drivers, Libraries and Resources==
| | {{Language_-_C_Dev_Environment_Table}} |
| Before you can run your program, you need to set up the proper environment and get the necessary files off the Phidgets website.
| |
| Visit the drivers section at www.phidgets.com and get the latest:
| |
| * [http://www.phidgets.com/drivers.php Phidget Framework]
| |
| You will need the Phidget Framework to use and to program with Phidgets. We also recommend that you download the following reference materials:

| * You can find a high level discussion about programming with Phidgets in general on the [[General API]] page.
| |
| * The [[Device Functionality]] page explains the general operational information for your device.

|
| You may want to have these pages open while working through these instructions.
| | == Quick Downloads == |
|
| |
|
| ==Getting Started (Windows)==
| | If you already know what you're doing and just need the files, you can find them all below. |
|
| |
|
| The Phidget examples were written using Visual C++ 2005 and this tutorial assumes its use.
| | === Documentation === |
| Other environments such as other versions of Visual Studio work as well and would be set up in a similar manner.
| |
| Borland C also requires the phidget21bcc.lib file provided at the Phidgets website.
| |
| Consult your compiler documentation for specific details on how to link to external libraries.
| |
| In Visual C++ 2005:
| |
|
| |
|
| * Generate a new C/C++ console project with a descriptive name such as PhidgetTest. | | *{{Phidget22API}} (select C from the drop-down menu) |
| * Copy phidget21.h and phidget21.lib from the VC/VC++/Borland examples and add them to your project directory.
| |
| * Open the project properties window.
| |
| * Navigate to Configuration Properties | Linker | Input.
| |
| * Edit the additional dependencies and add “phidget21.lib”.
| |
|
| |
|
| The project now has access to the Phidget21 function calls and we are ready to begin coding.
| | === Example Code === |
|
| |
|
| ===Setting up the Libraries===
| | *{{SampleCode|C|C Examples}} |
|
| |
|
| Before you can use the Phidget, you must include a reference to the library header.
| | ===Libraries=== |
|
| |
|
| <div style="background-color: #f3f3f3; border-color: #1c9edb; border-width:1px; border-style: dashed;">
| | {{AllQuickDownloads}} |
| <font size="3">
| |
| <source lang=cpp>
| |
| | |
| #include "phidget21.h"
| |
| | |
| </source>
| |
| </font>
| |
| </div>
| |
| | |
| Afterwards, the Phidget object will need to be declared and then initialized.
| |
| For example, we can declare a PhidgetInterfaceKit inside our main function with:
| |
| | |
| <div style="background-color: #f3f3f3; border-color: #1c9edb; border-width:1px; border-style: dashed;">
| |
| <font size="3">
| |
| <source lang=cpp>
| |
| | |
| int _tmain(int argc, _TCHAR* argv[])
| |
| {
| |
| CPhidgetInterfaceKitHandle ifKit = 0; //Declare an InterfaceKit handle
| |
| CPhidgetInterfaceKit_create(&ifKit); //Create the InterfaceKit object
| |
|
| |
| //More code goes here
| |
| return 0;
| |
| }
| |
| | |
| </source>
| |
| </font>
| |
| </div>
| |
| | |
| The object name for any type of Phidget is listed in the API manual.
| |
| Every type of Phidget also inherits functionality from the Phidget base class.

| ===Running Examples===
| |
| | |
| ===Writing Your Own Code===
| |
| | |
| You can use a Phidget in code by essentially by opening it, setting it up, doing things with it, and closing it. These steps are outlined at a high-level for all devices and languages on the [[General Phidget Programming]] page.
| |
| | |
| The complete set of functions you have available can be found in the [http://www.phidgets.com/documentation/Phidget21_C_Doc.zip C/C++ API]. More description about parts of the API can be found in our [[General API|API Overview]] general to all devices, or, where the calls are specific to a device, on the [[Device List|Device API]] page.

| |
| | |
| ===Compiling Your Program===
| |
| | |
| Compiling and linking against the Phidgets Library can be done in the following ways:
| |
| | |
| *To build on Linux:
| |
| :gcc example.c -o example -lphidget21
| |
| *To build on MacOS:
| |
| :gcc example.c -o example -framework Phidget21 -
| |
| :I/Library/Frameworks/Phidget21.framework/Headers
