Analog to Digital Converter With AVR Microcontroller

ADC: Analog to digital Converter:

ADC Pins and Registers

In ATMEGA16/32, PORTA contains the ADC pins. Some other features of the ADC are as follows:8 channel implies that there are 8 ADC pins are multiplexed together.

You can easily see that these pins are located across PORTA (PA0…PA7).10 bit resolution implies that there are 2^10 = 1024 steps

ADC Registers – ADMUX, ADCSRA, ADCH, ADCL.

ADMUX Register:

ADCSRA Register
