Welcome to using Phidgets with Windows!


==Recommended Languages==
If you are ready to go, the first step in creating Windows applications with Phidgets is installing our libraries.
We recommend the following languages for Windows:

Once installed, you should see a [[Image:Ph.jpg|border]] icon on the right hand corner of the task bar.
===Verify===
The best way to verify that your libraries are working properly is to use the Phidget Control Panel. The control panel is a powerful tool that will help you develop your Phidgets applications. Get started by following the instructions below:

===Issue: Installing .NET 2.0 on Windows 2000.===
Affected Operating Systems: '''Windows 2000'''


To install the Phidget Framework on Windows 2000 systems, the .NET 2.0 framework is required.
Find the [[File:Ph.jpg|link=]]  icon in the taskbar. If it is not there, open up the start menu and search for ''Phidget Control Panel''
Also, although not explicitly required to use Phidgets on a Windows system, Phidgets under the .NET languages can use .NET 2.0.

Solution: The Microsoft .NET Framework Version 2.0 Redistributable Package for (x86) and (x64)
systems is freely available from www.microsoft.com. You will need to upgrade to at least Windows
2000 Service Pack 3 for the (x86) version.

keys relating to the installer, the .NET library and the COM library, but they should not interfere with
anything.

When this happens, the device shows up in the Phidget Control Panel at start up but examples and programs are unable to make a connection to the Phidget.

Windows implements 200ms delayed ACKs for network traffic. When traffic is one-way only - as it is with event data, the data will all arrive in clumps every 200ms because of delayed ACKs.

This can be a great drawback for application which rely on low latency event data over the network. (source: http://support.microsoft.com/kb/214397)

This delayed ACK behavior can be disabled in windows to decrease event latency as documented here: http://support.microsoft.com/kb/328890
 
In the future, the Phidgets library may implement this differently, but so far we have been unable to match the performance achieved by disabling delayed ACK.

Getting Started with Windows

Welcome to using Phidgets with Windows!

If you are ready to go, the first step in creating Windows applications with Phidgets is installing our libraries.

Install

To install our libraries, download the installer for your system:

Before installing our libraries, be sure to read our Software License. If you need to access an old version of the drivers, click here.

When prompted, continue with the installation:

The libraries are now installed on your machine. Next, let's verify that they are working properly.

For instructions on installing our libraries without an installer, check out the OS - Windows Advanced Information page.

Verify

The best way to verify that your libraries are working properly is to use the Phidget Control Panel. The control panel is a powerful tool that will help you develop your Phidgets applications. Get started by following the instructions below:


Find the Ph.jpg icon in the taskbar. If it is not there, open up the start menu and search for Phidget Control Panel

The Phidget Control Panel can be used for testing devices, updating firmware, enabling a Phidget Network Server, and more! Visit the Phidget Control Panel page for more information.


Your Phidget is now able to communicate with your development machine. The next step is selecting a programming language so you can start to write some code!

Programming

Ready to write some code? Select one of the programming languages below:

Core Languages Mobile Languages Other Languages
C Sharp C# Objective C Objective C LabVIEW LabVIEW
C/C++ C/C++ Swift Swift Max/MSP Max/MSP
Python Python Android Android Java
