    Teensy 3.2 with Featherwing DC motor board

    Has anyone managed to get the Featherwing DC motor board to work with the Teensy 3.2?

    I have tried following the instructions here:

    And here:

    I have tried this set up:
    Teensy -> Featherwing
    3.3v - > BAT (no idea if this is the right way to supply logic power?)
    GND -> GND
    SCL0 (19/A5) -> SCL
    SDA0 (18/A4) -> SDA

    Motor connected and has it's own power supply via featherwing terminal. Made sure voltage is within acceptable range for motor driver and motor.

    I have also tried a variety of pull up resistors (2.2k, 2.7k, 4.7k) with i2c. Tried both the Wire library and i2c_t3.

    For the code I am using the library and code found here:

    I realize that it may be more appropriate to ask at the Adafruit forum but the motor driver is designed to work with in the featherwing 'eco system' and I would rather use the Teensy.

    Has anyone had any experience with this?

    Happy to provide more details if required...
