Notice: This page contains information for the legacy Phidget21 Library.

Phidget21 is out of support. Bugfixes may be considered on a case by case basis.

Phidget21 does not support VINT Phidgets, or new USB Phidgets released after 2020. We maintain a selection of legacy devices for sale that are supported in Phidget21.

We recommend that new projects be developed against the Phidget22 Library.

  • Windows-only release
    • Labview release to support older versions

2.1.8.20141119

  • OS X-only release
    • Fixed an issue with the 2.1.8.20141117 release where nothing was actually installed.

2.1.8.20141117

  • OS X-only release
    • Fixed a code-signing issue that make the installer appear unsigned on OS X 10.10
    • Dropped support for OS X 10.4

2.1.8.20140905

  • Windows-only release
    • Added an IA32 folder to the windows libraries download - this supports Windows on the Intel Galileo platform

2.1.8.20140428

  • Windows-only release
    • Fixes to C# Stepper GUI Example

2.1.8.20140319

  • CPhidget_getDeviceClass can now be called on handle before it is attached.
  • Added support for 64-bit Max/MSP (Version 6.1+) on both OS X and Windows.

2.1.8.20140227

  • Deals with 1046 bug in v100 and v101 firmware.
    • No longer reports bad values that appear right after a channel is enabled.
    • Fixes issue where changing the gain while channel 0 is disabled would sometimes cause bad readings.

2.1.8.20131105

  • Fixed a defect in the Flash examples for the 1012 (Outputs 11-16 were not addressed properly).

2.1.8.20130926

  • Windows-only release
    • Support setting label on 1067 from Windows

2.1.8.20130820

  • Windows-only release

2.1.8.20130802

  • Windows-only release
    • Fix for Windows 8 issue where only 'Uninitialized Phidget Handle' would show up in the Manager, and Phidgets could not be opened.

2.1.8.20130723

  • Improvement to java: we don't attach/detach our native threads for each event, just one attach, then detach before the thread exits.
    • This increases performance, esp. when debugging on Android.
  • Improvement to Android: We reuse the UsbRequest object rather then creating a new one for each transfer. This reduces logcat messages tremendously, and increases performance.

2.1.8.20130618

  • Changed setCompassCorrectionParameters() API call so that compass calibration parameters are written out to non-volatile storage on 1042/1044, so that they persist across power cycles. Previously, calibration data would need to be re-programmed at each attach.
  • Changes to C# Spatial example:
    • Compass calibration parameter set dialog removed from for 1042/1044 because parameters are set by the calibration software - and thus do not need setting in the example.
    • Stores/restores parameters for 1056 based on serial number, so multiple different calibrations can be maintained.

2.1.4.20080808

  • added CPhidgetSBC and CPhidgetSBCManager to the c library - these interfaces are hidden from users and meant to be used internally (for now).
  • CPhidgetManager_open no longer blocks to send out initial attach events. These initial events are sent from the CentralThread context like all other attach events.
  • fixed CThread_wait_on_event on Linux
  • added CPhidgetGeneric interface for prototyping to C, .NET libraries. product ID is 0x99. These are only visible in debug releases, only to be used internally.

2.1.4.20080715

  • udev rules fixed for product IDs with alpha-hex values
  • blocking in an attach event does not block calls to open anymore
  • RFID tag event handlers can now handle blocking - tag lost is timed after the tag handler exits.

  • Added ability to deprecate funcitons in the C library - compiler will issue a warning when they are used.
  • added names to some arguments in phidget21.h
  • fixes to the webservice for initial state stuff - now it behaves almost like non-webservice, with guaranteed initial events, but we don't guarantee initial state in the attach event yet. Min/Max, Num motors, inputs, etc. are all guaranteed in the attach handler.
  • Finalized support for Phidget Stepper

2.1.3.20080402

  • added:
    • CPhidgetStepper_getMaxMotorSpeed

    • device state is read in and preserved on attach
    • during attach event, all sensor data, etc. is provided if available
