Create the DogLcd object and specify the 4 pins where the LCD is connected. You can connect more than one LCD and create separate DogLcd objects for each.

lcd.begin(type);

Initialize the display. Type should be DOG_LCD_M081, DOG_LCD_M162, or DOG_LCD_M163.

lcd.print(anything);

Print a number or text. This works the same as Serial.print(), but prints to the LCD.

lcd.setCursor(x, y);

Move the cursor to position (x, y). These are zero-based coordinates.

Many other functions are available. See below for links to more details.

/*
  DogLcd Library - Hello World
 
  Demonstrates the basic use of a DOGM text LCD display.
 This sketch prints "Hello World!" to the LCD
 and shows the time.
 
 See the online-documention for wiring instuctions
 We assume  the following pins are connected:
 * LCD SI pin to digital pin 2
 * LCD CLK pin to digital pin 3
 * LCD RS pin to digital pin 4
 * LCD CSB pin to digital pin 5
 * LCD RESET pin is not used
 * LCD Backlight pin is not used

// include the library code:
#include <DogLcd.h>

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

void setup() {
  // set up the LCD type and the contrast setting for the display 
  lcd.begin(DOG_LCD_M162);
  // 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);
}
