Salve Guglielmo.
Credo di aver risolto il problema almeno parzialmente.Mentre aspettavo una risposta mi sono scaricato di nuovo librerie e codice del oled_clock.quello zippato come mi consigliavi.
Ora ritornandoci sopra per inviarvi il codice tutto è andato!Evidentemente avevo scaricato il codice incompleto come dicevi.
Mi spiace aver creato tutto 'sto ambaradan per così poco!
L'orologio sul display segna l'ora esatta e le lancette scorrono ,la data è quella esatta:12 Mar 2019
Forse sono troppo esigente ma ...il giorno è Sunday?
(A parte ciò mi viene da pensare che neanche un centesimo di questo tipo di codici potrò mai scrivere.Ma nella vita bisogna accontentarsi.)
Comunque anche se forse non serve ti mando il codice di Rinky-Dinky.

Fulvio
P.S.Magari in un altro momento chiederò lumi sull'orologio utf di Rinky.Per il momento vi do' pace.
