• Teensy 3.1/3.2

• Teensy 3.6

Note: Some of the following instructions require using Dave Hylands' micropython repository as some functionality has not been merged in micropython (see: #2513 #2519 #2520).

To build, you can either use the ARM toolchain from here (add to your PATH), or you can use the ARM toolchain included with Arduino/Teensyduino (set ARDUINO environment variable to point to the root of your arduino/teensyduino tree).

git clone https://github.com/micropython/micropython
cd micropython/ports/teensy
make BOARD=TEENSY_3.1

BOARD can be one of TEENSY_3.1, TEENSY_3.5, or TEENSY_3.6. If no BOARD is specified, then TEENSY_3.1 will be assumed.

The firmware will be in build-TEENSY_3.1/micropython.hex (replace TEENSY_3.1 appropriately).

You can flash using teensy_loader_cli or by using the flashing tools included with teensyduino but setting ARDUINO to point to the arduino/teensyduino tree.

make BOARD=TEENSY_3.6 deploy

Currently, scripts must be compiled into the firmware image. Place your .py files into the teensy/scripts directory and they'll be built into your firmware image.

The sample scripts directory includes a boot.py and main.py. The default main.py flashes the LED twice.

If you want to update a script, you'll need to rebuild and reflash the firmware.
