Teensyduino is a software add-on for the Arduino software.

Teensyduino Files:	Other Files:

Teensyduino 1.54 supports Arduino versions 1.8.5 and 1.8.9 and 1.8.12 and 1.8.13 and 1.8.14 and 1.8.15.
Future versions of Teensyduino will drop support for Arduino 1.8.14
On Windows, the Arduino installer and ZIP are supported, but the Windows store 'app' is not.
Windows 10 provides much better USB support than Windows 7, 8 & XP.
On Linux, PJRC tests X86 & AARCH64 on Ubuntu and ARM32 on Raspbian. Other distros may work, but are not supported.

Windows Installation

Download and run Arduino's Windows Installer, for Windows 7 and up.
Note: The Arduino 'Windows app' from the Microsoft Store is incompatible with Teensyduino.
Download and run the Teensyduino installer.
(optional) Check for anti-virus performance problems.

Macintosh Installation

Download Teensyduino for MacOS 10.10 - 11.x.
Note: This download is a complete copy of all software. No separate installer is used.
On first use, you must allow access to your Documents folder.

Linux Installation

Download the Linux udev rules (link at the top of this page) and copy the file to /etc/udev/rules.d.
Download and extract one of Arduino's Linux packages.
Note: Arduino from Linux distro packages is not supported.
Download the corresponding Teensyduino installer.
Run the installer by adding execute permission and then execute it.

Windows Non-Admin Installation

Download Arduino's Windows ZIP file for non admin install.
Extract the ZIP file, and remember the extracted location.
Download the Teensyduino installer. Save the file, do not run.
Rename TeensyduinoInstall.exe to Teensyduino.exe.
Note: Removing 'Install' from the name causes Windows to treat the installer differently!
Run the renamed Teensyduino installer. You will need to select the extracted Arduino location.
(optional) Check for anti-virus performance problems.

Old Macintosh Installation

Download Arduino 1.8.5 from Arduino's Previous IDE Releases Page.
Move Arduino to Applications.
Run Arduino and confirm running software downloaded from the internet.
Note: This must be done before installing Teensyduino, to avoid a corrupted install.
Download and run the Teensyduino Installer for MacOS 10.7 - 10.14.

Teensyduino Graphical Installer

The Teensyduino installer adds the necessary support files to Arduino.Your copy ofArduino must be one of the supported versionslisted on this first screen.On Windows, this driver allows to you access the serial device type.This step is not necessary and does not appear on Mac OS-X and Linux.Windows 10 has the proper driver, which is automatically detected.Select the location where you extracted the Arduino Software.On Windows, the location will default to the location whereArduino's installer places the software.

The Next button will only activate when a supported version of the Arduino Software is found.If the Next button will not activate, click the '?' button formore information.Teensyduino can automatically install many libraries that are testedand verified to work with Teensy. Usually it's best to allow theinstaller to add them all.The installer will copy all the necessary files into your ArduinoSoftware, when you click the 'Install' button.When installation is finished, you will see this final screen. Justclick Done to quit the installer.When using Arduino, be sure to select Teensy in the Tools > Boardsmenu. Arduino's File > Examples menu automatically changes toshow the libraries and examples for the selected board.

Command Line Install

The Teensyduino installer supports a non-graphical command line install,using '--dir=<directory>' to specify Arduino's location.

For example, the following commands can be used to install Arduino andTeensyduino on a Linux 64 bit x86 system, and compile usingthe sample makefile for Teensy 4.0.
