Teensyduino Graphical InstallerThe 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 InstallThe 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.

Version 0.2Change API to use Serial.print to talk to USB.Fix pinout Many bugs fixed Version 0.1Initial releaseKnown IssuesWindows:Windows Defender and many anti-virus programs can dramaticallyslow down code compilation. A modern PC should take less than 10 seconds toverify simple programs. If Arduino takes 1 minute or longer to verify simpleprograms, that is a sure sign anti-virus software is slowing you down.Configuring Windows Defender so that it does not check intermediate Arduino buildfolders & products (to keep it from slowing down the build). 1) Open Windows Defender 3) Click on 'Exploit protection settings' 4) Click on 'Program settings' 5) Click on 'Add program to customize' & specifically select 'Choose exact file path' 6) Navigate to the location where your Arduino IDE is installed (typically 'C:ProgramFiles (x86)Arduino'), highlight the 'arduino.exe' executable & click 'Open' 7) Activate the 'Override system settings' checkbox for every option & verify that theyare all turned off (make sure to scroll down the list to get everything) 8) Click 'Apply' to complete the process. Special thanks to Mark J Culross (KD5RXT) forcontributing these Windows Defender instructions. Macintosh: Teensyduino requiresaccess to your Documents folder, because Arduino stores installed libraries andboards in Documents/Arduino. If you have disallowed access to Documents,Teensyduino may fail to open. To solve this problem, open System Preferences,click Security & Privacy, and select Files and Folders. Then findTeensyduino on the list of applications which have requested access toyour Documents Folder. This box must be checked for Teensyduino to work. All: Serial + Keyboard + Mouse + Joystickrequires 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 whencombined with other types. Windows & Linux: When using the Serial Monitor withthe USB Keyboard/Mouse option, sometimes a 'teensy gatewaycommunication error' can occur. Close and reopen the serialmonitor to regain communication. Windows: You may need to run the Teensyduino installer asadministrator for it to install all files. Some anti-virusprograms can also interfere with installation and must betemporarily disabled. ANorton AntiVirus Workaroundwas sent by Carl B. All: The Upload button can only work if your Teensy is runninga previously loaded sketch. If your board can not be rebootedautomatically, a message will ask you to press the reset button. Mac OS X: When you run Arduino after installing Teensyduino, theLeopard's firewall will recognize the program has changed and willask again if you wish to allow internet connection (Arduino checksfor 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.linux32and TeensyduinoInstall.linux64 files will not have execute permission enabledwhen 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 toolchainprovided by your system. As of December 2011, Gentoo's avr-gcc is horriblybroken. Some newer Fedora (avr-gcc 4.6.x) also have trouble. FaultyAVR toolchains are a persistent problem on Linux. Please report bugs to paul@pjrc.com CreditsThe Teensyduino installer is based in part on the work ofthe FLTK project (http://www.fltk.org).Numerous files covered by various open source licenses are installedby Teensyduino. Nearly all are provided in source code form. Pleaserefer to the comments within each file for copyright and licensinginformation.
