Hello,

i bought new LCD display... It is 16x2, it doesnt have HITACHI, but SAMSUNG S6A0069 driver, it seems they are not 100% compatible in initialization. I tried the Lib4wire or LiquidCrystal libraries. Both worked just when display was initialized just for first line. When it is initialized as two lines display, it just dont work.

I searched a lot of phorums, but there was no solution. I also tried initialization from samsung datasheet. It worked, but i ahd problem to get cursor to second row, when i moved to addres over 0x40, unfortunately cursor wasnt in second row... :frowning:

Does anybody has some experiences with souch a displays?

Thank you

Jan
