Pin.h

Purpose: Logical GPIO pin and port identifiers.

Namespace: atmega328p::pin

Pin identifies the silicon signal. It does not identify a package terminal.

#include <atmega328p/Pin.h>
 
namespace mcu = atmega328p;
 
constexpr mcu::pin::Pin led = mcu::pin::Pin::PB5;
constexpr mcu::pin::Port port = mcu::pin::Port::B;

The root aliases atmega328p::Pin and atmega328p::Port are retained for short existing code. New code can use the explicit pin namespace.
