I am planing a DSF77 clock.
At first I try an LCD display and realiced this: http://arduino.cc/en/Tutorial/LiquidCrystal
I use arduino nano with this display: Anag Vision AV1611YFBY  (16 digits 1 line)
(http://www.conrad.de/ce/de/product/181687/LCD-Punktmatrix-Modul-Anag-Vision-AV1611YFBY-WJ-Zeichenformat-16-x-1-Zeichenhoehe-806-mm/SHOP_AREA_17651?)
Now I have a problem: there words only 8 digit, I see only: hellow, w
I checked all connections to disply and checked low state and the high state. Wy are ther working only 8 digits?
Need I an other LCD library or other connetions? May be, that LCD Display bad?

Upload the code you using, and how you connecting it, and some photos if you can.

That way people in forum can help you easily.

Every thing I did is writen on link.
here is the sketch:
// include the library code:
#include <LiquidCrystal.h>

// initialize the library with the numbers of the interface pins
LiquidCrystal lcd(12, 11, 5, 4, 3, 2);

void setup() {
  // set up the LCD's number of columns and rows:
  lcd.begin(16, 1);
  // Print a message to the LCD.
  lcd.print("hello, world!");
}

void loop() {
  // set the cursor to column 0, line 1
  // (note: line 1 is the second row, since counting begins with 0):
}

I don't think this is the problem, but, have you tried?

Code: [Select]
lcd.begin(16, 2);

At least it figures that way on the page you sent http://arduino.cc/en/Tutorial/LiquidCrystal
