Buenas noches.
Estuve mirando un tutorial sobre los modulo de tiempo real
El que tengo es un ds3231sn
Yo copie un codigo que estava en github con sus respetivas librerias pero me aparece un error como este

me podrian orientar como puedo solucionar ese error?
estuve mirando el error pero sospecho que la libreria no funciona
