| ==Getting Started with Windows== | | ==Getting Started with Windows== |
| | Welcome to using Phidgets with Windows! |
|
| |
|
| ===Installing===
| | If you are ready to go, the first step in creating Windows applications with Phidgets is installing our libraries. |
| | | |{{TOC limit|3}} |
| The Phidget installer requires that your system has .NET framework 3.5 or higher. The .NET framework can be downloaded from [http://www.microsoft.com/net Microsoft].
| |
| | |
| If you're not sure which versions of the .NET framework are installed on your computer, you can check by clicking on the start menu and running "regedit". Navigate to {{Code|HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\NET Framework Setup\NDP}}, and you'll find one or more folders that list the version numbers you currently have installed. | |
| | |
| If you are unable to install .NET framework 3.5 or higher, you can still use Phidgets. However, you won't be able to use the installer, and will have to manually install the Phidget libraries. Please see the [[#Advanced Uses | Advanced Uses]] section.
| |
| | |
| To install the libraries, follow these steps:
| |
| | |
| 1. Download one of the Phidget installer for your system, depending on whether your system is 32 or 64-bit.
| |
| *[{{SERVER}}/downloads/libraries/Phidget-x86.exe 32-bit]
| |
| *[{{SERVER}}/downloads/libraries/Phidget-x64.exe 64-bit]
| |
| | |
| 2. Open up the installer, and proceed through the wizard.
| |
| | |
| [[image:Windows_Install.png|link=]]
| |
| | |
| Please note that by default, the installer places the [[#Description of Installer files | Phidget libraries]] in {{Code|C:\Program Files\Phidgets\Phidget22}}.
| |
| | |
| 3. Once the installation is complete, you are ready to program with Phidgets. To find out what files got installed, please see [[#Description of Installer files | Description of Installer files]] in the Appendix section.
| |
| | |
| Next, the Phidget Control Panel will be discussed.
| |
| | |
| ====Phidget Control Panel====
| |
| | |
| The Phidget Control Panel is a tool to quickly determine whether your system is able to communicate with Phidgets, and also acts as a debugging tool.
| |
| | |
| Once the Phidget libraries are installed using the installer, you should see the [[File:Ph.jpg]] icon in the taskbar. If you don't, open up the start menu and search for "Phidget Control Panel". Once you run that, you should see the icon. Double click on the icon to bring up the Phidget Control Panel.
| |
| | |
| [[File:Windows ControlPanel General.PNG|link=|alt=Windows Control Panel General]]
| |
| | |
| The Phidget Control Panel can:
| |
| * Access and test Phidgets connected to your computer
| |
| * Update device firmware
| |
| * Access other Phidgets and make your local Phidgets accessible over the [[Phidget Network Service]]
| |
| * Access [[Phidget Dictionary]] obejcts over the Phidget Network Service
| |
| * View all [[OS_-_Phidget_SBC|SBCs]] on the network and view their webpages
| |
| | |
| '''For more information, visit the [[Phidget Control Panel]] page.'''
| |
| | |
| ===Checking===
| |
| | |
| To confirm the libraries were installed and work correctly, you can check both the hardware and software components of the interface. It is worth checking the software side first, because if it works then you know the hardware side is also okay.
| |
| | |
| ====Software====
| |
| | |
| If you have the Phidgets library installed on your system, you can verify that the software side component is working by seeing if a Phidget device is listed in the {{Code|Phidgets}} tab of the Phidget Control Panel.
| |
| | |
| [[File:Windows_ControlPanel_General.PNG|link=|alt=Windows Control Panel General]]
| |
| | |
| The above screenshot shows that a VINT Hub is attached to the computer. If you see your Phidget in the list, you can continue to the [[#Programming Languages | programming languages]] section to learn more. If you are not able to see that the Phidget is in the list, there may be a hardware issue. Please see the [[#Hardware| hardware]] section for more details.
| |
| | |
| ====Hardware====
| |
| | |
| You can verify that your computer detects that the Phidget is plugged in through a USB connection by going to the Windows Device Manager.
| |
| You can access the Device Manager by accessing the start menu, and searching for "Device Manager". The Device Manager window will open.
| |
| | |
| [[File:Windows_DeviceManager.PNG|link=|alt=Windows Device Manager]]
| |
| | |
| Under the {{Code|Human Interface Devices}} heading, you can view whether your computer detects that the Phidget is connected through the USB if it is in the list. There should be a {{Code|HID-compliant device}} and a {{Code|USB Input Device}} entry for every Phidget that is attached to the computer. A simple way of verifying which entry belongs to which Phidget is to simply connect or disconnect the Phidget from the USB port of the computer. The list will automatically refresh to show the updated list of all connected USB devices.
| |
| | |
| Another place you can see attached Phidgets is "Devices and Printers" which you can also open by searching for it in the start menu.
| |
| | |
| [[File:Windows_DevicesAndPrinters.jpg|link=|alt=Devices and Printers]]
| |
| | |
| Here, all Phidgets will show up under the "Unspecified" category.
| |
| | |
| If you don't see the Phidget in either list, try the following things:
| |
| | |
| * If the Phidget is connected to your PC through a USB hub, try connecting it directly to a USB port on your computer.
| |
| * If your Phidget requires an external power supply, make sure that a supply of the correct voltage is connected.
| |
| * If you're using an old USB cable, try switching it out for one you know is working.
| |
| * Try switching to a different USB port on your computer.
| |
| * Try connecting the Phidget to a different computer, especially if you have one that has worked with other Phidgets previously.
| |
| | |
| If you've tried all of these things and the Phidgets still don't show up, don't hesitate to {{ContactUs|ask us}} for help.
| |
| | |
| ====Troubleshooting====
| |
| | |
| If the examples '''do not''' work but USB '''does''' work (i.e. your computer can consistently see the device in the [[#Hardware|hardware]]), take a moment to check the basics:
| |
| * You are using Windows 7 or newer.
| |
| * You have .NET framework 3.5 or higher.
| |
| * No other programs, drivers, or processes are using that USB port in software. Some drivers or software will sometimes mistakenly claim Phidget devices when waiting on some hardware to be connected. Please see the section: [[#Issue: Some third party software prevents communications with Phidgets|third party software prevents communications with Phidgets]] for more information.
| |
| * The Phidget libraries are the latest version (visit the [[#Quick Downloads| getting started section]] to download them)
| |
| * Check the [[#Common Problems and Solutions|common problems]] section below, some specific combinations can cause problems
| |
| | |
| If your problem doesn't seem to be fixed by these steps, make sure that the Phidget is seen '''consistently''' by USB (if it is erratic, try our [[General Troubleshooting|general troubleshooting guide]]). If you are still having problems after using the troubleshooting guide, please {{ContactUs|ask us}}!
| |
| | |
| ==Programming Languages==
| |
| | |
| Phidgets’ philosophy is that you do not have to be an electrical engineer in order to do projects that use devices like sensors, motors, motor controllers, and interface boards. All you need to know is how to program.
| |
| | |
| After you have installed the drivers and tested your Phidgets using the Control Panel, you should pick a programming language, install libraries, and run the examples for that specific language. You can learn more about what is needed to program in a particular language by choosing the language of your preference below. If you need help choosing a language, please look at the [[Software Overview#Language Support |language comparison table]].
| |
| | |
| If you have never programmed before, we recommend using one of these languages due to their widespread use (which means it'll be easier to find help online, and your programs will have more options available if you need to combine Phidgets with another system or technology):
| |
| | |
| *[[Language - C Sharp|C#]]
| |
| *[[Language - C/C++|C/C++]]
| |
| *[[Language - Java|Java]]
| |
| *[[Language - Python|Python]]
| |
| | |
| Phidget22 also supports the following languages under Windows:
| |
| | |
| *[[Language - Javascript|Javascript]]
| |
| *[[Language - Visual Basic .NET|Visual Basic .NET]]
| |
| *[[Language - LabVIEW|LabView]]
| |
| *[[Language - Max/MSP|Max/MSP]]
| |
| | |
| ==Phidget Network Service==
| |
| | |
| The Phidget Network Service allows you to remotely control Phidgets over a network. For more information, please see the [[Phidget Network Service]] page.
| |
| | |
| Drivers for the Phidget Network Service on Windows are already included in the [[#Quick Downloads | Drivers]] above. If you have a [[File:Ph.jpg]] icon in your taskbar, you already have the Network Service installed.
| |
| | |
| There are two ways that you can connect to a Phidget hosted on another computer. The first method is by using the IP address/host name and port of the host computer. The second method makes the use of [http://en.wikipedia.org/wiki/Multicast_DNS mDNS], which allows Phidgets to be found and opened on the network by a server id instead of an IP address/host name. When using a server id, both the client and server will need to be running an implementation of zero configuration networking. The Phidget Network Service takes advantage of the [https://support.apple.com/kb/DL999?locale=en_US Bonjour] software. It is a tool, developed by Apple to locate devices such as Phidgets, and printers. You will have to install Bonjour onto your system to use the second method.
| |
| | |
| This section helps you install, check, and use the Network Service on Windows, but we also have an overview of the [[Phidget Network Service]] in general.
| |
| | |
| ===Turning the Network Service On and Off===
| |
| | |
| Double click on the [[File:Ph.jpg|link=]] icon in the system tray to bring up the Control Panel window. In the {{Code|Network Service}} tab, you can start, restart or stop the Network Service. You can also choose to have the Network Service start up automatically upon Windows boot up by selecting {{Code|Automatic}} as the {{Code|Startup Type}}. By leaving the {{Code|Startup Type}} as {{Code|Manual}}, you will have to manually turn the Network Service on everytime you wish to use it. You'll need administrator privileges in order to make changes to these settings. You can see the status of the Network Service at the bottom of the window, where it will say "Network Service: Running" or "Network Service: Stopped".

| |
| | |
| [[File:Windows_ControlPanel_NetworkService_Running.jpg|link=|alt=Windows Control Panel Network Service Setup]]
| |
| | |
| ===Using the Network Service===
| |
| | |
| To use a Phidget over the Network Service, you'll want to:
| |
| * Have two different computers connected to the same network. We will call the computer that has the Phidget directly connected to the USB port the host. The client will be the computer that runs a Phidget application to connect to the Phidget attached to the host. Please note that if you only have a single computer, you can also connect to the Phidget over the Network Service. The computer will simply act as both a host and client. This will allow you to bypass the [[General Phidget Programming # Details for Open() | one application per Phidget limitation]].
| |
| | |
| * Start the Network Service on the computer that directly connects to the Phidget
| |
| * Run your program on the remote computer that will control the Phidget over the network
| |
| | |
| The easiest way to test these steps on Windows is [http://www.apple.com/support/downloads/bonjourforwindows.html download] and install Bonjour onto both the host and client. Next, we will set up the WebService and run the Phidget program on the client. Please follow these steps:
| |
| | |
| 1. On the host, open up the Phidget Control Panel and traverse to the {{Code|Setup}} tab of the {{Code|WebService}} section.
| |
| | |
| [[File:Windows_ControlPanel_WebService_Setup_Stopped.PNG|link=|alt=Windows Control Panel WebService Setup Stopped]]
| |
| | |
| 2. Leave all fields the way they are, and click on {{Code|Start}} to run the WebService.
| |
| | |
| 3. You can determine that the WebService is running by looking at the WebService status at the bottom of the window. | |
| | |
| [[File:Windows_ControlPanel_WebService_Setup_Running.PNG|link=|alt=Windows Control Panel WebService Setup Running]]
| |
| | |
| 4. Ensure that the Phidget is plugged in to the host.
| |
| | |
| 5. On the client's Phidget Control Panel, open up the {{Code|Bonjour}} tab in the {{Code|WebService}} section. You will see the Phidget that is plugged into the host as one of the entries listed. Double click it to open the example application.
| |
| | |
| [[File:Windows_ControlPanel_WebService_Running.PNG|link=|alt=Windows Control Panel WebService Bonjour]]
| |
| | |
| 6. The example application will open up, and you will be able to communicate with the Phidget over the WebService.
| |
| | |
| [[File:Windows_ControlPanel Example.PNG|link=|alt=Windows Control Panel Example]]
| |
| | |
| 7. You can confirm that the WebService was indeed behind this exchange by terminating the WebService process while still allowing the remote program to run. On the host's Phidget Control Panel, traverse to the {{Code|Setup}} tab of the {{Code|WebService}} section. Hit {{Code|Stop}} to terminate the WebService.
| |
| | |
| [[File:Windows_ControlPanel_WebService_Setup_Running.PNG|link=|alt=Windows Control Panel WebService Setup Running]]
| |
| | |
| 8. Take a look at the example application on the client. Since the application can no longer connect to the WebService, the attached state of the Phidget is false.
| |
| | |
| [[File:Windows_ControlPanel_WebService_Example_Disconnected.PNG|link=|alt=Windows Control Panel WebService Example while WebService Stopped]]
| |
| | |
| ===Debugging the WebService===
| |
| | |
| In addition to enabling [[General Phidget Programming#Logging|logging]] in your Phidget code, you can get additional debugging information from the WebService itself. This additional debugging can be enabled from the {{Code|Enable verbose output}} checkbox in the Phidget Control Panel.
| |
| | |
| [[File:Windows_ControlPanel_WebService_Setup_Running.PNG|link=|alt=Windows Control Panel WebService Setup]]
| |
| | |
| The debugging information is shown in the {{Code|Output}} tab.

| |
| | |
| ==Advanced Uses==
| |
| | |
| ===Manual File Installation===
| |
| | |
| The Phidget installer installs the most commonly used files onto your system. However, there may be special cases where you want to install the Phidget libraries without the automatic installer. This section will describe the purpose of the most important files file and cover how to manually install the libraries. You can get the files [{{SERVER}}/downloads/libraries/Phidget22-windevel.zip here]. Once you've moved every file and folder in that .zip into the locations in the table in the next section, your manual installation will be complete.
| |
| | |
| ====Description of Library files====
| |
| | |
| Here is the list of files and their description for each file the installer puts onto your system. You don't need to know this if you're just using our installer, but if you are looking to distribute our libraries with your code (without your clients having to use our installer) this list will help you pick and choose what you need. Please note that not all of these files are available in the package linked above.

| | ===Install=== |
| | To install our libraries, download the installer for your system: |
| | *[https://cdn.phidgets.com/downloads/phidget22/libraries/windows/Phidget22-x86.exe 32-bit Installer Download] |
| | *[https://cdn.phidgets.com/downloads/phidget22/libraries/windows/Phidget22-x64.exe 64-bit Installer Download] |
|
| |
|
| ===Windows in a Virtual Machine===
| | Before installing our libraries, be sure to read our [[Software License]]. If you need to access an old version of the drivers, [https://www.phidgets.com/downloads/phidget22/libraries/windows/ click here]. |
| | |
| Phidgets can also be used inside a virtual machine. Instructions for VMWare and VirtualBox are provided below. Virtual PC is not supported as USB Phidgets requires a virtual platform that supports HID USB Devices and since Virtual PC does not support HID USB devices, Phidgets may not be used.
| |
| | |
| As always, please ensure that you have the latest Phidget [[#Quick Downloads | drivers]] installed on the virtual machine and that you are using the latest version of your virtual software.
| |
| | |
| <b>VMWare:</b>
| |
| | |
| To enable USB Phidgets, select Virtual Machine -> Removable Devices -> and select the Phidget Input Device -> Connect.
| |
| | |
| <b>VirtualBox</b>
| |
| | |
| To enable USB Phidgets, VirtualBox Guest Additions(Devices -> Install Guest Additions) may need to be installed. Afterwards, click on Devices -> USB Devices and select the Phidget device to enable. The state should go from Busy to Captured. VirtualBox may bring up a new hardware wizard in the host operating system, which has to be installed. Please note that Phidgets with USB hubs (for example, the [{{SERVER}}/products.php?product_id=1019 1019 Interface Kit with 6-port hub]), are undetectable; Fortunately, Phidgets that are attached to such Phidgets are detectable.
| |
| | |
| Note that Windows XP "mode" in Windows 7 does '''not''' support Phidgets.
| |
| | |
| ===Installing Without an Internet Connection===
| |
| When running the Phidgets installer it will check for other applications such as .NET. Part of this requires an active internet connection. The downside to this is that even if you have the applications installed already, if you do not have an internet connection you cannot complete the installation process. There is a way around this however which involves extracting the Phidget22 .msi file out of the .exe installer. To do this follow these steps:
| |
| | |
| *Run the installer.
| |
| | |
| [[image:Windows_Install.png|link=]]
| |
| | |
| *Once the installer has started up and you are at the first informational window, navigate to your
| |
| {{Code|Local Disk\Users\"username"\AppData\Local\Temp}} folder.
| |
| *Look for the most recently modified folders. The Phidgets one will not have an obvious title, most likely a seemingly random string of numbers and characters.
| |
| | |
| [[image:Windows_Installer_Folder.jpg|link=]]
| |
|
| |
|
| *In this example the folder was named "IXP000.tmp" but it may be different for you. In the folder you will find the {{Code|Phidget22_x64.msi}} or {{Code|Phidget22_x86.msi}} file. This file can be run to install the Phidgets libraries without needing an internet connection.
| | When prompted, continue with the installation: |

| |
|
| ==Common Problems and Solutions==
| |
|
| |
|
| ===Issue: Software projects are not working after a Phidget22 reinstall===
| | The libraries are now installed on your machine. Next, let's verify that they are working properly. |
| Affected Operating Systems: '''Windows'''
| |
|
| |
|
| Solution: You need to reset your references and library paths. When you reinstall the Phidgets drivers all of the old paths can get broken. Make sure that you are including the correect header files and that you have referenced the correct libraries and that should fix the problem.
| | ''For instructions on installing our libraries without an installer, check out the [[OS - Windows Advanced Information]] page.'' |
|
| |
|
| ===Issue: Some third party software prevents communications with Phidgets=== | | ===Verify=== |
| Affected Operating Systems: '''Windows'''
| | 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: |
|
| |
|
| Some drivers or software will sometimes mistakenly claim Phidget devices when waiting on some hardware to be connected.
| |
| This is caused by the drivers taking every HID (human interface device) on the USB bus, effectively stealing them from the Phidgets drivers.
| |
| 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.
| |
| This has been known to occur with Logitech QuickCam, Force Feedback Mouse, Nike, Velleman K8055, and some SteelSeries drivers.
| |
|
| |
|
| Solution: If you suspect this is a problem then try putting your machine in safe mode. If this fixes the problem you can be sure that this is the problem. Try shutting/uninstalling the offending driver/software down or kill its process in the task manager when using Phidgets.
| | 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'' |
| | [[File:Windows PhidgetTaskbar.PNG|link=|center]] |
|
| |
|
| ===Issue: A corrupt installation fails on uninstall or repair===
| |
| Affected Operating Systems: '''Windows'''
| |
|
| |
|
| Solution: If the normal uninstall fails, for whatever reason, you can choose to remove the Phidget drivers manually.
| | Next, double-click on the Phidgets icon to bring up the Phidget Control Panel. You can now see all the Phidgets that are plugged into your machine, as well as any Phidgets that are on the network: |
| Please perform the following:
| | [[File:Windows ControlPanel General.PNG|link=|alt=Windows Control Panel General|center]] |
| # Shut down any programs and processes using the Phidget libraries, including the Network Service and the Phidget Control Panel.
| |
| # Delete {{Code|C:\Program Files\Phidgets\}}
| |
| # Remove the Phidgets key from the Registry {{Code|[-HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\ Phidget22NetworkService]}}.
| |
|
| |
|
| In most cases this is enough to get the installer working again. If you need to remove all traces of the Phidgets libraries manually, perform the following additional steps:
| |
|
| |
|
| # Remove {{Code|Phidget22.NET}} from {{Code|C:\Windows\Assembly\}}.
| | Click on the '''+''' beside a device to expand it so that you can see all available channels. Double-click on one of these channels to open up a window that lets you interact with it.: |
| # Delete {{Code|C:\Documents and Settings\All Users\Application Data\Phidgets}} if you are using Windows XP or {{Code|C:\Users\All Users\Phidgets}} if you are using Windows Vista.
| | [[File:Controlpanel_openapplication.png|500px|link=|alt=Windows Control Panel General|center]] |

| '''NOTE:''' You can go through the registry and purge any other keys mentioning Phidgets if you still have problems, but at this point you should be able to reinstall under most cases. There will also be keys relating to the installer, the .NET library and the COM library, but they should not interfere with anything.

| ===Issue: Event data is sporadic/slow/clumped over the WebService===
| | The Phidget Control Panel can be used for testing devices, updating firmware, enabling a Phidget Network Server, and more! Visit the [[Phidget Control Panel|Phidget Control Panel page]] for more information. |
| Affected Operating Systems: '''Windows'''
| |
|
| |
|
| 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 applications which rely on low latency event data over the network. (source: http://support.microsoft.com/kb/214397)
| | 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! |
|
| |
|
| This delayed ACK behavior can be disabled in windows to decrease event latency as documented here: http://support.microsoft.com/kb/328890
| | ==Programming== |
| | Ready to write some code? Select one of the programming languages below: |
|
| |
|
| 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.

| ===Issue: Windows XP "mode" in Windows 7 does not work with Phidgets=== | | ==Advanced Information== |
| Affected Operating Systems: '''Windows''' (running XP in included XP mode)
| |
|
| |
|
| Although XP supports some USB devices, its overall device support is spotty. If you need to run XP within a virtual machine, Phidgets work under both VMWare and VirtualBox - the two main virtual machine programs. However, this means you will need to own a copy of Windows XP to install into the virtual machine.
