The standard Arduino lcd library

2011-05-25 23:06:37 Hi,
It is possible to use the Standard LiquidCrystal.h with the LCD/Keypad Shield.
In the Examples>Liquid Crystal> Hello world.pde example
You need to change the pins as follows:
The circuit:
* LCD RS pin to digital pin 8
* LCD Enable pin to digital pin 9
* LCD D4 pin to digital pin 4
* LCD D5 pin to digital pin 5
* LCD D6 pin to digital pin 6
* LCD D7 pin to digital pin 7
So the line should look like this:
// initialize the library with the numbers of the interface pins
LiquidCrystal lcd(8, 9, 4, 5, 6, 7);
This should get you started with the LCD shield and the standard library.
