Field Oriented Control of 3-phase AC brushless motor, C2812 and MSP430F5438
Motor control is demonstrated using Clarke transforms (converting between 3-phase and 2-phase equivalent), Park transforms (converting between stationary reference frame and rotating reference frame), and Space Vector PWM to control the motor phase power FETs. After demonstrating motor operation using a 150 MHz C2812 with a 20 KHz control loop, the code base was highly optimized and ported to a 25 MHz MSP430F5438 with the same 20 KHz control loop.

Energy Harvester / Combiner, C28035 (Piccolo B with CLA)
A power harvester is developed that interfaces with an existing legacy product. The harvester collects and combines power from four different sources into a single output supply producing a single 5.3V output supply.
Power source maximum current limits are enforced in software.
The control loops are synchronous and phase-shifted to balance the time-averaged power moving into the output caps.
The control loops are executing simultaneously (interleaved within the PWM period) in the CLA. Code for the DSP’s CLA is highly pipelined and written in Assembly Language.

Endodontic device, C2408
An Apex Locator dental device (used to find the bottom of a tooth during root-canal procedure) is developed. The device synthesizes a very low voltage complex waveform through the hand-held dental tool and the response of the tooth is measured and sampled. FFTs are performed continuously to determine the position of the hand-held dental tool within the tooth. An LCD display is updated to show tool position within the tooth. Sounds are generated when certain events occur.
