Hello everybody ...
i've searched through the forum but didn't find something to solve my prob.
I'm using a 40x2 LCD with the Hitachi HD44780 controller.
I use the LiquidCrystal lib to run the display ... however those 40x4 LCDs act like two 40x2 LCDs. I've connected everything like it is in the LiquidCrystal lib tutorial on arduino.cc (arduino.cc/en/Tutorial/LiquidCrystalSerial) and addionally the 2nd Enable of the Hitachi to pin 10 on the arduiino. How do i have to use the LiquidCrystal lib to run the whole display ???? Deos it manage the "two" LCDs?
thx for any help
