I have a couple XBEEs and my Arduino Duemilanove with nkc’s xbee shield V3.
As my first mini-project/learning experience I want to have my Duemilanove w/ xbee recieve data from a remote xbee with a temperature sensor (with or without an arduino, not sure yet. I don’t know how to program the xbee yet, so I might start off with one of my breadboard arduino’s doing the work) and display it on a serial LCD.
As a start, mostly because I don’t have any sort of interface for my second xbee to connect it to another arduino (yet), i want to display text sent from an xbee connected to my desktop (via xbee explorer USB). This requires two software serial “ports” on the Duemilanove. One for the LCD and one for the XBEE.
To restate, I want text (or anything really) sent from the xbee connected to the computer to appear on the LCD on the arduino (which recieves the data from it’s own arduino).
Using ladyada’s xbee tutorials as a guide, I have not been able to figure it out, so I thought I’d ask for help rather than waste time.
#include <NewSoftSerial.h>
int LCDrx = 15;
int XBEErx = 2;
int XBEEtx = 3;
NewSoftSerial LCDSerial = NewSoftSerial(LCDrx, 255);
NewSoftSerial XBEESerial = NewSoftSerial(XBEErx, XBEEtx);
char buffer = 0;
void setup()
{
pinMode(13, OUTPUT);
LCDSerial.begin(9600);
XBEESerial.begin(9600);
LCDSerial.print("?G216"); // set display geometry, 2 x 16 characters in this case
delay(100); // pause to allow LCD EEPROM to program
LCDSerial.print("?B80"); // set backlight to ff hex, maximum brightness
delay(100); // pause to allow LCD EEPROM to program
LCDSerial.print("?s6"); // set tabs to six spaces
delay(1000); // pause to allow LCD EEPROM to program
LCDSerial.print("?f"); // makes sure the LCD is cleared.
}
void loop()
{
...?
}
Thanks!
