SainSmart 20 x 4 LCD wanting to use I2C from Arduino Uno

Using Arduino Displays
56

We have the same library and the display should probably work the same. The display is disconcerting on start-up and you might think it is faulty. The light comes on and then goes goes off, then comes on fully operational.

Here is the start of a clock. Note that I don't define the backlight pin.

//Arduino 1.0+ Only
//Arduino 1.0+ Only

#include <LiquidCrystal_I2C.h>
#include "Wire.h"
#define DS1307_ADDRESS 0x68

LiquidCrystal_I2C lcd(0x27,20,4);  

void setup(){
  Wire.begin();
  Serial.begin(9600);
  lcd.init();  
    delay(1000);
 lcd.clear();
      lcd.backlight();  //Backlight ON if under program control
      lcd.setCursor(0,0); 
  // Print a message to the LCD.
 lcd.print("Today it is");
 
}

void loop(){
  printDate();
  delay(1000);

}
