One of the best ways to start programming with Phidgets is to use our example code as a guide. Before we get started, make sure you have read [[#Install Phidget Python module for Windows | how to install the Phidget Python module]] section above. You will also need to download [http://www.liclipse.com/ LiClipse] if you have not already.
 
Now that you have Python and the Phidget Python module installed, as well as LiClipse, select an example that will work with your Phidget:

To start, you need to create your project as shown in the previous section.
To start, create a new Python project:
 
[[Image:Python_liclipse_newproject.PNG|link=|center]]
To include the Phidget Python library, add the following line to your code:


<syntaxhighlight lang=python>
from Phidget22.PhidgetException import *
from Phidget22.Phidget import *
</syntaxhighlight>


Then, you will also have to add a reference to your particular Phidget. For example, you would include the following line for a DigitalInput:
Next, add a new file to the project:
[[Image:Python_liclipse_newfile.PNG|link=|center]]


<syntaxhighlight lang=python>
==Using the Code Samples==
from Phidget22.Devices.DigitalInput import *
</syntaxhighlight>


The project now has access to Phidgets.
Now that you have configured a project to use Phidgets, you can copy the code sample from the [{{server}}/?view=code_samples&lang=Python Code Samples] page into your project, and run it.

Language - Python

Windows with LiClipse

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

LiClipse is a closed-source development environment based on Eclipse, with support for Python.

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
  2. You will need a version of Python installed on your machine (2.7 and 3.6+ are compatible with Phidgets).


The recommended way to install the Phidget22 Python module is using the PIP package manager.

Python versions 2.7.9+ and 3.4+ include PIP by default.

To install the Phidget22 Python module with PIP, simply open the Command Prompt (press the Windows key and search for "cmd"), and enter the command: 

python -m pip install Phidget22

To install the Phidget22 libraries to a specific Python version, you can use the Python Windows Launcher from the Command Prompt as follows (replace -X.X with your Python version, e.g. -2.7 or -3.6): 

py -X.X -m pip install Phidget22

To install the Phidget22 Python module without PIP, you will need to download the Phidget22 Python module.

After unpacking the Phidget22 Python module, open the Command Prompt (press the Windows key and search for "cmd") Locate the folder where you downloaded the Python module and enter the following command: 

python setup.py install

This will build the module and install the Python module files into your site-packages directory.

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.

Setting Up a New 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 Python library.

To start, create a new Python project:

Python liclipse newproject.PNG


Next, add a new file to the project:

Python liclipse newfile.PNG

Using the Code Samples

Now that you have configured a project to use Phidgets, you can copy the code sample from the Code Samples page into your project, and run it.

What's Next?

Now that you have set up Phidgets to work with your programming environment, we recommend you read our guide on Phidget Programming Basics to learn the fundamentals of programming with Phidgets.Next Arrow.png
