Define Documentation
#define BAUD_DIV  52
This is the baud rate divisor for the serial port. It should give 9600 baud for the CPU crystal speed in use; for example, 26 works for a 4MHz crystal

Function Documentation
int main ()
The main function is the "entry point" of every C program, the one which runs first (after standard setup code has finished). For mechatronics programs, main() runs an infinite loop and never exits.
Returns:
Although a mechatronics program never returns (there's no OS to return to), we generally have to return something, such as zero, to keep the compiler happy
