Setup

Install the Teensy udev rule: sudo cp tools/49-teensy.rules /etc/udev/rules.d/

Then unplug your Teensy and plug it back in.

Using

1. Put your code in src/main.cpp
2. Put any libraries you need in libraries
3. Set the TEENSY variable in Makefile according to your teensy version
4. Build your code make
5. Upload your code make upload

Make Targets

• make alias for make hex
• make build compiles everything and produces a .elf
• make hex converts the elf to an intel hex file
• make post_compile opens the launcher with the correct file
• make upload uploads the hex file to a teensy board
• make reboot reboots the teensy

Thanks to Austin Morton for the template

Teensy 3.X Project Template github.com/apmorton/teensy-template

Where everything came from

• First download your favorite Arduino src and install Teensyduino
• The teensy3 sub-folder is taken from <path-to-arduino-x.y.z>/hardware/teensy/avr/cores/teensy3
• The tools sub-folder is taken from <path-to-arduino-x.y.z>/hardware/tools and/or Teensyduino
• The src/main.cpp file is moved, unmodified from teensy3/main.cpp
• The 49-teensy.rules file is taken from PJRC's udev rules

Modifications to Makefile include

• Add support for arduino libraries
• Change tools directory
• Calculate target name from current directory
• Prettify rule output
• Do not upload by default, only build
