Yes, uStepper_S takes STEP/DIR but from it's own uP.. which to my understanding uses internal RC clock, not stable enough for our applications. you will have to modify the board in order to provide external signals from teensy or Arduino MEGA), which would then be similar h/w configuration that I am using.
BTW, onSTEP f/w can be configured for Arduino MEGA + RAMPS1.4 (all that available for couple of $$ on ebay, widely used for 3D printers and CNC machinery)
