MacOS 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 macOS (see Part 1 of this user guide)

● gcc

You likely have gcc installed on your macOS machine already, but if not, you can easily get it by downloading Xcode.

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

To compile the program, enter the following command in the terminal, substituting "example" for the name of your C file:

gcc example.c -o example -F /Library/Frameworks -framework Phidget22 -I /Library/Frameworks/Phidget22.framework/Headers

Finally, run the program by entering the following command in the terminal:

./example

Success! The project is now running with Phidgets.

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.
