buenas amigo aquí de nuevo ahora con otro problema en principio ya logro ver y escribir los datos en el ds1307 pero ahora es como cambiar el formato de 24 horas a 12 horas (yo sé que es con unos de los bit de la dirección que contiene la hora pero no sé cómo controlarlo), por otra parte como controlar la salida SQW/OUT (sé que es con él registro de control pero no me funciona en la práctica solo en el simulador ) de ante manos muchas gracias.
He aquí el programa
