I'm back playing with my Arduino MEGA 2580 and its "LCD Keypad Shield v2.0" but I'm facing some problem.
It only displays the first left 8 caracters on line 0 and lone 1
The right area stays blind.http://robotbase.en.alibaba.com/product/357645038-217010522/LCD1602_keypad_shield_v2_0_for_Arduino_compatible.html
The code I'm using :
LiquidCrystal Library - Serial Input
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 displays text sent over the serial port
(e.g. from the Serial Monitor) on an attached LCD.
* LCD RS pin to digital pin 12 ==> 8
* LCD Enable pin to digital pin 11 ==> 9
* LCD D4 pin to digital pin 5 ==> 4
* LCD D5 pin to digital pin 4 ==> 5
* LCD D6 pin to digital pin 3 ==> 6
* LCD D7 pin to digital pin 2 ==> 7
* LCD R/W pin to ground
* 10K resistor:
* ends to +5V and ground
* wiper to LCD VO pin (pin 3)

This example code is in the public domain.
// include the library code:
// initialize the library with the numbers of the interface pins
LiquidCrystal lcd(8, 9, 4, 5, 6, 7);
// set up the LCD's number of columns and rows:
// initialize the serial communications:
// Print a message to the LCD.
// set the cursor to column 0, line 1
// (note: line 1 is the second row, since counting begins with 0):
// print the number of seconds since reset:
But it does the same problem with different code.
I've got RS, E, D4, D5, D6, D7 respectively on pin 8, 9, 4, 5, 6 and 7.
Any idea what could be wrong ?
Would it be possible something blownup ?
