Download Teensyduino, Version 1.30Teensyduino is a software add-on for the Arduino software.
Teensyduino 1.30 supports Arduino versions 1.0.6 and 1.6.5-r5 and 1.6.8 and 1.6.9 and 1.6.10 and 1.6.11.
Arduino 1.6.12 support is currently in beta testing.
Install Step 1: Download & Extract ArduinoFirst, you must download the Arduino Software. Remember the location where you extracted the files.
Install Step 2: (Linux only) Install udev RulesThe udev rule file gives non-root users permission to use the Teensy device. More Linux tips below.
sudo cp 49-teensy.rules /etc/udev/rules.d/
Install Step 2: (Macintosh only) Pass Internet Download QuestionYou must run Arduino at least once before adding Teensyduino, to confirm you wish to run a program downloaded from the Internet.
If Teensyduino modifies your copy of Arduino before you confirm, recent versions of OS-X may not allow you to run Arduino, or even tell you Arduino will damange your computer. Simply run Arduino first to clear the question about running a program downloaded from the Internet, before adding Teensyduino!
Install Step 3: Run Teensyduino InstallerThe Teensyduino installer adds the necessary support files to Arduino.

Many bugs fixed
Version 0.1Initial release
All: Serial + Keyboard + Mouse + Joystick requires Mac OS X Lion, or Windows XP SP3, Vista SP1, or Windows 7, or Linux 2.6.18 or later. Mac Snow Leopard and Windows XP SP2 do not support Serial when combined with other types.
Windows & Linux: When using the Serial Monitor with the USB Keyboard/Mouse option, sometimes a "teensy gateway communication error" can occur. Close and reopen the serial monitor to regain communication.
Windows: You may need to run the Teensyduino installer as administrator for it to install all files. Some anti-virus programs can also interfere with installation and must be temporarily disabled. A Norton AntiVirus Workaround was sent by Carl B.
All: The Upload button can only work if your Teensy is running a previously loaded sketch. If your board can not be rebooted automatically, a message will ask you to press the reset button.
Mac OS X: When you run Arduino after installing Teensyduino, the Leopard's firewall will recognize the program has changed and will ask again if you wish to allow internet connection (Arduino checks for updates). Teensyduino does not "phone home", but Arduino does! TODO: is this still an issue with recent versions of Arduino??
Linux: By default, the TeensyduinoInstall.linux32 and TeensyduinoInstall.linux64 files will not have execute permission enabled when saved by most web browsers. Use a file manager or type "chmod 755 TeensyduinoInstall.linux32" in a terminal to make the file executable. Then you can run it. In a terminal, type "./TeensyduinoInstall.linux32". Replace "32" with "64" if using the 64 bit version, or "arm" if using the ARM (Raspberry Pi) version.
Linux: Teensyduino only works with Arduino from www.arduino.cc. The modified version provided by Ubuntu is not (yet) supported.
Linux (especially Gentoo): Arduino uses the AVR toolchain provided by your system. As of December 2011, Gentoo's avr-gcc is horribly broken. Some newer Fedora (avr-gcc 4.6.x) also have trouble. Faulty AVR toolchains are a persistent problem on Linux.
Please report bugs to email@example.com
