Care stie il rog sa ma ajute.Am de facut un ceas sa imi afiseze ore, minute, luni si ani.Cu orele si minutele am rezolvat dar nu gasesc o solutie pentru luni. Am facut numaratoarele de 28, 30 si 31 dar nu stiu cum sa le leg intre ele in asa fel incat cand termina de numarat prima luna sa treaca la a 2-a si tot asa.

Circuite integrate CMOS - Manual de utilizareEditura Tehnica 1986la pagina 411pentru 30/31 mai intra un bistabil, la 28 sunt probleme. cred ca ar mai trebui un numarator cu 12 si o initializare undeva, sau un al doilea bistabil, cu o basculare unica (si apoi o inhibare) si cu index la ianuarie
