LCD panel

I just got that LCD display I'm on the right port but nothing seems to happen.

OPEN---->LiquidCrystal---->Display

It uplaod to the board fine but nothing appears on the display

I assume you are talking the Display example from the library. You need to double check which pins the LCD is on and make sure those are the pins you have defined in the sketch on this line.

LiquidCrystal lcd(12, 11, 5, 4, 3, 2);

EDIT: Found this schematic on that LCD. http://www.robotshop.com/content/PDF/dfrobot-lcd-keypad-shield-schematic.pdf

You do in fact need to change which pins the sketch uses. You need to change it to this. LiquidCrystal lcd(8, 9, 4, 5, 6, 7);

Cool thanks it works :D

Anyone tried using
displaytech 162 display?

The contrast controlling works fine, but nothing displays on the screen…

#include <LiquidCrystal.h>

// LiquidCrystal display with:
// rs on pin 12
// rw on pin 11
// enable on pin 10
// d4, d5, d6, d7 on pins 5, 4, 3, 2
byte d4 = 9;
byte d5 = 10;
byte d6 = 11;
byte d7 = 12;

byte en = 5;
byte rs = 12;
//byte rw = gnd; 

LiquidCrystal lcd( rs, en, d4, d5, d6, d7);

void setup()
{
  // Print a message to the LCD.
  lcd.begin(16, 2);

  lcd.print("hello, world!");
}

void loop()
{
}

I think i see the problem. Tie the RW pin directly to ground.

Problem was that D5 on my arduino doesn't work, who would have guessed that. I figured it out when i turned the display into 8 bit mode, then there was a bit missing. Change it to pin 13 and now it works superb...

I guess i need to run out and get a new chip....
