i have connected a compatible display to my arduino
using arduino ide 1.01
the display is a CU20025ECPB-U1J
only the following pins are connectedno other pins are connected
lcd to UNO
pin 1 --- ground
pin 2 --- 5v
pin3 --- not con------contrast
pin 4 --- uno pin 7 --- RS
pin5 --- not con ---- RW
pin 6--- uno pin 6 --- enable
pin7 --not connect ---db0
pin8 -- not conn --- db1
pin 9 --- not conn --- db2
pin10 --- not conn --- db3
pin 11 --- uno pin 5 ---- db4
pin 12 --- uno pin 4 ---- db5
pin 13 --- uno pin 3 ---- db6
pin 14 --- uno pin 2 --- db7
the proble is hello, world is displayed as h e l l o , w o r (with spaces)
ok here are the exect printing and location
display location
h e l l o , w o r
any idea how i can fix this
here is the code

LiquidCrystal Library - Hello World
Demonstrates the use a 16x2 LCD display. The LiquidCrystal
library works with all LCD displays that are compatible with the
Hitachi HD44780 driver. There are many of them out there, and you
can usually tell them by the 16-pin interface.
This sketch prints "Hello World!" to the LCD
and shows the time.
The circuit:
* LCD RS pin to digital pin 12
* LCD Enable pin to digital pin 11
* LCD D4 pin to digital pin 5
* LCD D5 pin to digital pin 4
* LCD D6 pin to digital pin 3
* LCD D7 pin to digital pin 2
* LCD R/W pin to ground
* 10K resistor:
* ends to +5V and ground
* wiper to LCD VO pin (pin 3)

// include the library code:
#include <LiquidCrystal.h>
// initialize the library with the numbers of the interface pins
LiquidCrystal lcd(7, 6, 5, 4, 3, 2);
void setup() {
// set up the LCD's number of columns and rows:
lcd.begin(20, 2);
// 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):
//lcd.setCursor(0, 1);
// print the number of seconds since reset:
//lcd.print(millis()/1000);
