    dear
    i wan to display cmp03 compass value in lcd can any one suggest how to interface with lcd to show data ?/*


    This will display a value of 0 - 359 for a full rotation of the compass.

    The SDA line is on analog pin 4 of the arduino and is connected to pin 3 of the CMPS03.
    The SCL line is on analog pin 5 of the arduino and is conected to pin 2 of the CMPS03.
    Both SDA and SCL are also connected to the +5v via a couple of 1k8 resistors.
    A switch to callibrate the CMPS03 can be connected between pin 6 of the CMPS03 and the ground.

    #include <Wire.h>

    #define address 0x60 //defines address of compass

    void setup(){
    Wire.begin(); //conects I2C
    Serial.begin(9600);
    }

    void loop(){
    byte highByte;
    byte lowByte;

    Wire.beginTransmission(address); //starts communication with cmps03
    Wire.send(2); //Sends the register we wish to read
    Wire.endTransmission();

    Wire.requestFrom(address, 2); //requests high byte
    while(Wire.available() < 2); //while there is a byte to receive
    highByte = Wire.receive(); //reads the byte as an integer
    lowByte = Wire.receive();
    int bearing = ((highByte<<8)+lowByte)/10;

    Serial.println(bearing);
    delay(100);
    }

    ok i got 4 and 6 then 11 12 13 14 of lcd respective order yes

    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)
