Description

This is an abstract class for Analgo/Digital Converters (ADC). Typically each ADC requires an individual implementation for data access, so create derived classes for each ADC. You must override all abstract methods to enable reading of single pin data. If the chip also supports differential or pseudo differential measurement, you should override DifferentialValue and GetDifferentialValue, also.
