xbee question

By hyper terminal, do you mean the serial monitor?  Simply stated, instead of doing the Serial.writeln(" Hello World ") you would myLCD.writeln(" Hello World ").  The myLCD library is created using the techniques and library provided by the vendor/distributor/manufacturer of the LCD.

I'm using arduino interface ...myLCD is another library? (I know the liquidcrystal libraray)

but anyway I think I understand what you mean

I understand that anyway's that the LCD have to be attached to an arduino and I only have 1 (mega2560 r3) so what i will try to do is other way around (connect the transmitter xbee to the pc and send a msg from the XCTU and try and display it to the receiver connected to lcd screen (and the two of them will be connected to the arduino) and order another board and then try again

HI there i finally had some time to work on my project yayiii

anywho what I did 

1.connected xbee to the xctu (he is the transmitter one) with xbee explorer (direct connection to the usb entrence in my laptop)

2.connected the second xbee to arduino

3.connected the lcd to the arduino also

4. my program is such :

/*

the circuit  :

LCD -

* 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)

*/

//includes

#include <LiquidCrystal.h>   //LCD library

// initialize the library with the numbers of the interface pins

LiquidCrystal lcd(12, 11, 5, 4, 3, 2);

void setup() {

  // set up the LCD's number of columns and rows:

              lcd.begin(16, 2);

            Serial.begin(9600);

            lcd.setCursor(0,0);

}

void loop() {

  if(Serial.available( ) > 0 ) {

      lcd.print(Serial.read());

}

}

I've tried to run in on the arduino and type something on the terminal and xctu and it doesnt come up on my lcd screen

any ideas why and what should i do?

ok apperantly it does work however one problem when I type anything on the keyboard in order to transmit then instead of the the letter i get the ascii tabke number of it (for example if I type j on the keyboard instead of j  appear on the screen I get an 106 which is the ascii value for j )

how to fix this problem in my code?

You've found the helpful, and correct answers, as you've marked yourself.

In theory they should be present in each respondants reply, but visible only to you.

I might be wrong but you could try this.

I suspect your

lcd.print(Serial.read());

is treating what it reads as an integer, rather than a character, so when you print its simply a number rather than the ascii equivalent of the character j.

try

  if(Serial.available( ) > 0 ) {

  char input = Serial.read();

      lcd.print(input);

  }

and see if it fixes it.
