Detailed Description

Contains functions and definitions for using the ADC.

Contains definitions and function prototypes for using the ADC to detect analog signals on pins AN0 - AN7. AN6 and AN7 are used for the wheel and battery.

The pins labeled E6 and E7 are external interrupt pins and are not related to analog.
