==Use Our Examples==
{{Finding Code Samples|C}}
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].


==Using the Code Samples==
To use the code sample from the [{{server}}/?view=code_samples&lang=C Code Samples] page, you can click the '''Download Example''' button to download a C file with the sample code.


Now that you have either MinGW or Cygwin installed, select an example that will work with your Phidget:

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:
Once you have the example, you can compile and run your code:

Language - C

Windows with GCC

Welcome to using Phidgets with C! By using C, you will have access to the complete Phidget22 API, including events.

GCC is a compiler system for originally written for GNU, and is the standard compiler on unix-like operating systems. It is available on Windows by using tools like MinGW or Cygwin to allow compilation of C programs from the command line.

Install Phidget Drivers for Windows

Before getting started with the guides below, ensure you have the following components installed on your machine:

  1. You will need the Phidgets Windows Drivers

Finding Code Samples

To find the code sample to use for your Phidget, navigate to the Code Samples page and select your device from the drop-down menu.

Once you select your device, the code sample generator will give you a working code sample, and a selection of options to customize it to your needs.

Using the Code Samples

To use the code sample from the Code Samples page, you can click the Download Example button to download a C file with the sample code.

Once you have the example, you can compile and run your code:

Compile and Run

In order compile C programs from the command prompt, you will need to download and install either MinGW or Cygwin.

Next, navigate to the folder where your code is and open the command prompt.

The specific command you will use depends on your compiler of choice. Select the tab for your compiler below, and enter the command within to compile your program, substituting "example" for the name of your C file: 

gcc example.c -o example -I"/cygdrive/c/Program Files/Phidgets/Phidget22"-L"/cygdrive/c/Program Files/Phidgets/Phidget22/x86" -lphidget22


gcc example.c -o example -I"/cygdrive/c/Program Files/Phidgets/Phidget22" -L"/cygdrive/c/Program Files/Phidgets/Phidget22" -lphidget22


gcc example.c -o example -I"C:/Program Files/Phidgets/Phidget22" -L"C:/Program Files/Phidgets/Phidget22/x86" -lphidget22


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 program: 

example.exe
