Code Overview

	Three sets of code were required for our project: the MATLAB code for the user interface, C code for the master PIC, and C code for the slave PICs. The MATLAB code set up a GUI for intuitive control of the ball. The master PIC code read all the serial communication from MATLAB and converted it into appropriate I2C commands for the slave PICs, which were completely dedicated to motor control and encoding. All required code is provided below (note an additional file BKSMotorControllerFunctions.c which is used by the master PIC as well).

			At the time of our presentation, we were able to demonstrate rotation along two axes by using the drive motor and Lazy Susan. Additionally, we were able to show effective and consistent communication of multiple bytes of data from MATLAB to the master PIC vis RS-232. Unfortunately, we were unable to get the hardware for I2C working, despite the code working on Matt's setup. Overall, we were pleased with our progress in a relatively short amount of time.

			We hope to fix the hardware issue in the near future and possibly consolidate all the circuitry onto a PCB for a more robust device. We would also like to add a hall effect switch or limit switch to indicate a set "Home" position. Additional work can be done on the motor control functions to implement feedback control as necessary. As there are clients that would like to see this project come to fruition, we want to make sure they are given a robust and flexible system for their use.
