Ich bin glaub ich wie immer mal zu blöd dazu!
Ich versuch einfach mal ein simples lcd anzusteuern aba es funktioniert
nicht!
Ich Krieg nur Blödsinn aufs LCD und der kontrast is von erster zu 2.
Zeile extrem unterschiedlich!
verwende die lib vom lieben fleury!
Programm:

lcd verwend ich jenes das als anhang beigelegt ist!
verwend die oberen 4 datenbits und halt die steuerleitungen!
