    Hi JC,

    1) The DRV8886AT can connect to any mcu if:
    a) The GPIO Voh voltage is >1.6V and the GPIO Vol voltage is <0.8V
    b) A PWM output is available to control the STEP pin
    c) A GPIO output is available to control the DIR pin

    2) The STEP/DIR control method uses an internal indexer table to control the stepper motor. Please refer to section 7.3.3 (Microstepping Indexer) of the datasheet for details. The indexer changes the percentage of current according to the table.
