13 ADC, fundamentals, operation, how to program the registers, circuits and coding examples

Microcontroller register level programming for the ATmega2560 This nutshell explains the Analogue to Digital Convertor (ADC). Analogue and digital signals are discussed, ADC resolution, voltage resolution quantization errors and reference voltages are explained, The ATmega2560 ADC features and circuit examples are shown. The internal register architecture is described with the five registers, ADCH, ADCL, ADCSRA, ADCSRB and ADMUX showing how they are interconnected, there functions and how to program them. The steps in programming the ADC and examples of single channel and multichannel conversions are shown.
