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.

Preamble about the OS.

Recommended Languages

We recommend the following languages for this OS:

Installing Libraries and Drivers

You can download the newest source below:

Phidgets requires Linux Kernel 2.6 or newer.

Once you've downloaded the source, build Phidget21.

There is no Phidgets Control Panel written for Linux, but there are C/C++ and Java code samples are available for all Phidgets which will compile and run on Linux without modification.

Notes:

  • Many Linux systems are now built with unsupported third party drivers. It may be necessary to uninstall these drivers for our libraries to work properly.
    • I don't think this is true. If you mean libusb- you need to install the 'libusb-dev' package. If you mean the kernel drivers - these don't interfere and are safe.
  • Phidget21 for Linux is a user-space library. Applications typically have to be run as root, or udev/hotplug must be configured to give permissions when the Phidget is plugged in.
