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.

Requirements

First, make sure you have the following installed:

● Phidgets Drivers for Windows (see Part 1 of this user guide)

● One of the following:

- MinGW

- Cygwin

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

If it's unclear what any of the options do, click on the nearby '?' for more info.

Once you've made your selections, click the Download Example button under Downloads.

Compile and Run

Go to the folder where your code is and open the command prompt by typing 'cmd' in the address bar.

The specific command you will use depends on your compiler of choice:

Cygwin x86:

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

Cygwin x64:

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

MinGW:

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

Compile and Run

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

What's Next?

Now that you've set up Phidgets in your C programming environment, you should read our guide on Phidget Programming Basics to learn the fundamentals of programming with Phidgets.

In particular, you should ensure that you familiarize yourself with how error handling is done in C, because it's not automatically implemented like in other programming languages. Once you've added error handling to your code, you can use the Error Code List to anticipate and handle various errors.
