Guest PicNick Posted January 19, 2008 Share Posted January 19, 2008 Salut!Am conectat un PIC 16F648A la un afisor de tipul DEM 16216 SGH.Portul B este conectat la pinii de date DB0-DB7Problema: cand alimentez afisorul pe toti pinii lui apare 5V.A mai lucrat cineva cu acest afisor?E corect sa-mi apara acele tensiuni?Sau e defect afisorul? E cumparat de la Conex ElectronicMerci! Quote Link to comment Share on other sites More sharing options...
Guest PicNick Posted January 19, 2008 Share Posted January 19, 2008 S-a rezolvat, conectasem pinul de reglaj contrast LCD la 5V ceea ce inseamna contrast minim, si nu vedeam nimic pe ecran Quote Link to comment Share on other sites More sharing options...
