This is an X-Plane plugin and an iPhone app that lets you use the iPhone as a remote control yoke/joystick for X-Plane.

The X-Plane plugin acts as a server, to which the iPhone app sends commands. This is currently implemented simply as a UDP socket with no verification or connection acknowledgement.

Please note that the iPhone app (in the ios-app directory) and the X-Plane plugin are under two different open-source licenses.

The iPhone app is licensed under the MIT license. See the file ios-app/License.txt for the full license.

The X-Plane plugin is licensed under the GPL. See the file xplane-plugin/GPL.txt for the full license.

The X-Plane plugin also includes 3rd party code under separate licenses:

• bsd-strlcat.c copyright 1998 Todd C. Miller. See that file for license info.
• Code from WidgetLibraryExample copyright 2005 Sandy Barbour and Ben Supnik. See the file 'Third Party/license.txt' for license info. This library is currently available online at http://www.xsquawkbox.net/xpsdk/mediawiki/XPWidgetsLibEx

• Center and bounds ideas:
  • Two-finger drag for additional axes, e.g. 3-D cockpit panning.
  • Double-tap to re-center, or for tilt, set tilt center.
  • Double-tap to set current value as the tilt center?
  • Null-zone
• Change color/sound to alert when tilt exceeds tracking bounds.
• Auditory feedback of tap-drag for better blind interaction.
• Eye candy: background images, pulsating trackpad dot...etc.
• Landscape mode with multiple trackpads or buttons -- maybe something like the AR Drone Free Flight app.

• Make server update on every flight loop instead of a fixed rate (20Hz)?
• Auto-coordinate roll+yaw should move nosewheel steering more.
• Send instrument readings back to iPhone for display?
• Bonjour/zeroconf
