TIDA-00111

This bipolar stepper motor system implements an MSP430, a DRV8818, and a NEMA 23 motor.  It's suitable for applications requiring up to 140 oz-in of torque, and up to 800 RPM.  Motor voltage support is 8V to 35V, and max current is 2.5A.  A multitude of configuration options allow fine tuning of the current waveform, including the regulated current level, the microstepping applied, H-bridge FET states during current decay, the time interval of current decay, and current deglitch time.  The motor drive stage has integrated protection from short-circuit, shoot-through, under-voltage, and over-temperature.
