This plugin for the X-Plane simulator allows sharing of flight simulator variables with Arduino sketches running on Teensy. A video demo is available here.

Since the development of Teensy 3.0 in late 2012, PJRC simply as not had the resources to continue developing this plugin. This source code is being released in the hope it can benefit software developers and flight simulatation enthusiasts, who might be able to update is needed for newer versions of X-Plane. In 2015, Jorg Bliesener provided some additions for datarefs with more than 58 characters, a cross-compile build script and a patch that resolves crashes on exit for OSX.

There is a compiled version of the plugin in the target folder of this repository. You can download it as either a zip file or as a directory. Copy it to your X-Plane's Resources\plugin folder. After this, you should have the following folder structure:
-+- X-Plane 10
|--- ...
|-+- Resources
|--- ...
|-+- plugins
|-+- ...
|-+- TeensyPlugin
|-+- 32
| |--- lin.xpl
| |--- win.xpl
|
|-+- 64
| |--- lin.xpl
| |--- win.xpl
|
|--- mac.xpl
A makefile is provided to build the code. Simply type "make" on the command line to build the code. There is no support for other build environments (eg, GUI-based IDEs).
The makefile requires the X-Plane SDK to be copied to the "SDK" folder. The X-Plane SDK is not distrubuted with this code. You must obtain it separately and copy its contents to the SDK folder.
You need to edit the Makefile to select your operating system. Building on Macintosh requires the X-Code command line utilities, available from Apple's developer program (historically, available without paying the developer subscription). Building on Linux may require installing the "libudev-dev" package.
If you get errors while compiling, the X-Plane forum is the place to ask for help.
PJRC built the plugin for Windows using the MinGW cross compiler running on Ubuntu Linux.
To install the necessary software on Ubuntu Linux, use one of these commands:
sudo apt-get install mingw32 mingw32-binutils mingw32-runtime
sudo apt-get install gcc-mingw-w64-x86-64 binutils-mingw-w64-x86-64
Then simply edit the makefile and run make, as with the other systems. A script is provided to automate copying the compiled code to a Windows machine named "xp" on your local network. Of course, that Windows machine must be running a FTP server. If a password is required, you can automate it with ".netrc" in your home directory.
This plugin has never been compiled on a native Windows system. Paul does not use Windows and will not be pleased if asked any questions regarding how to build this code on Windows. There is no technical support of any kind for this code, but especially when it comes to native Windows compilation, please do not ask. Building on Linux is the best way.
Once you have the the standard build procedure working, you may want to create a so-called "fat" plugin, that contains all six architectures (Windows, Linux and OSX, each on 32 and 64 bits). Actually, that will give you five binaries, as the OSX version contains 32 and 64 bits in a single file (see http://www.xsquawkbox.net/xpsdk/mediawiki/BuildInstall#Fat_Plugins)
The provided shell script makeall.sh was developed and tested by Jorg Bliesener on a Linux 64 bit machine running Fedora 22. It has an extensive list of prerequisites, notably osxcross (https://github.com/tpoechtrager/osxcross), which requires a dedicated download and setup procedure. Please check the comments at the start of the makeall.sh file about what is required to run it.
The TeensyControls plugin code is loaded with printf() lines, which by default are not compiled. To enable these, edit TeensyControls.h. Uncomment these lines, and edit the IP number to the computer where you will display the messages.
//#define USE_PRINTF_DEBUG
//#define PRINTF_ADDR "192.168.194.2"
//#define PRINTF_ADDR "127.0.0.1"
The printf output is transmitted to a server which listens for these messages and prints them to a terminal. The source code for this server is in the "listen" directory. It has only been used on Linux.
