Muy buenas compañeros me planteo una duda y a ver si se pudiera hacer algo ,tengo este código y e trabajado con el y todo muy bien,ahora la pregunta es la siguiente¿puedo cambiar en el código la librería por la i2c? se que el código esta preparado para la liquidcrystal normal pero con i2c me ahorro mucho cableado pues es para colocarlo en un sitio muy pequeño y esto me ahorra mucho espacio y dolores de cabeza.
si es asi me ¿podeis ayudar en conseguirlo?
Gracias de antemano.
