AnalogComparator.h

Purpose: Analog comparator input and interrupt definitions.

Namespace: atmega328p::analog_comparator

The header describes comparator input pins, interrupt modes, internal bandgap support, and the ADC multiplexer interaction.

#include <atmega328p/AnalogComparator.h>
 
namespace mcu = atmega328p;
 
constexpr mcu::analog_comparator::InterruptMode trigger =
    mcu::analog_comparator::InterruptMode::RisingEdge;
 
static_assert(mcu::analog_comparator::count == 1, "One comparator");

The ADC multiplexer path has configuration restrictions. Follow the datasheet before enabling that path.
