Hi, i'm trying to connect a PCF8574 with a display and control it with arduino UNO.
i've read some tutorials but nothing is showing in the lcd only light up backlight... i'm using proteus to simulate...
i've downloaded LiquidCrystal_I2C.h library but its not helping...
that is a picture of the connections:
I'm Using the Hello World example:
LiquidCrystal_I2C lcd(32,16,2); // set the LCD address to 0x20 for a 16 chars and 2 line display
lcd.init(); // initialize the lcd
// Print a message to the LCD.
anyone know what is happing? thanks
