Speeding up the ADC on an Arduino ATMega 328P

This is a continuation of the performance enhancements for reading the ADC on Arduino.  Similar steps apply to many non Arduino/ATMega processors. That other article is here: Arduino Library Functions & Macros and introduces startSample(), sampleDone(), and getSampleResult() as a way of avoiding blocking when doing an analogRead.  Here we will update the second two functions and introduce a new function: startFreeRunningADC(). […]
