Getting CAN working on a Teensy 3.6
A Teensy 3.6 is an ideal board for making a CAN-compatible device. It's generally compatible with Arduino sketches and hardware, which makes it relatively simple to go from an Arduino-based prototype to the finished article.
Get Teensyduino
The Teensy IDE is a modified version of the Arduino software. You can download it here. Even though it's a separate program, it will make use of your previously-installed Arduino libraries and sketches. Which is pretty neat.
Connect your CAN transceivers
Good news: you can use the same SN65HVD230-based CAN transceivers that you use with a Due. Connect them up using the pinout guide shown.
