Design Considerations  Micro Peripheral Usage  Output Interfacing  2x 8bit PWM for motors (PWM0, PWM1)  2x 8bit PWM and 2x 16bit PWM for servos (PWM2, PWM3, PWM5, PWM7)  Input Interfacing  3x 8bit ATD for sonar (PAD0, PAD1, PAD2)  2x SCI for GPS (4,800bps) and Atom (19,200bps)  PS0, PS1, PS2, PS3  Atom Peripheral Usage  Output Interfacing  SCI for micro  Input Interfacing  USB for camera

Design Considerations  Micro Application Code  Using a hybrid system of both polling and interrupts  Using vectored interrupts for all input devices  Using a polling loop to set all output devices  Atom Application Code  Uses a polling loop running as fast as the algorithm will allow.
