Arduino Due with USB Weatherboard

Has anyone done this project yet, using the Due with the sparkfun USB weatherboard. I have been trying to get them to work together but there is no code that is designed for the Due with the weatherboard. I must be hooking into the wrong input on the Due. Any help would be great.

String weatherSentence = "";  // string to read data from the weather board
int ready = 0;                // used to mark when we have a complete string to process
char data;                    // use to read a byte from the serial 
char charArray[100];          // create a char 100 position char array por parsing the data

unsigned long humidity=0, fahrenheit=0, celcius=0, SCPfahrenheit=0, presure=0;

void setup() { 
  Serial1.begin(9600);        // starts the second hardware serial port at 9600 to communicate with the weather board 
  Serial.begin(9600);         // starts the serial at 9600 
  pinMode(48, OUTPUT);        // turn ON the board LED for diagnostics 
  digitalWrite(48, HIGH);     
} 

void loop() { 
  while(Serial1.available() > 0) {  // if data vailable from the weather board 
    data = Serial1.read();          // read it 
    if((data != '\n')) {            // if no end of line 
      weatherSentence += data;      // add it to the string
    } 
    else {  // if end of line reached, readu to parse the buffer 
      ready = 1; 
      break; 
    }  
  } 
  if(ready == 1) {                         // parse the buffer 
    if(weatherSentence.startsWith("#")) {  // verify if it is a good reading 
      // Serial.println(buffer);           // uncomment just to see what we got 
      weatherSentence.toCharArray(charArray, 100);  // get the characters copied into charArray of size 100
      processReading(charArray);           // parse the char array extracting the data 
    } 
    weatherSentence = "";                  // clean up the string for next reading 
    ready = 0; 
  } 
} 

// function that parses information received in a char array 
void processReading(const char packet[]) { 
  byte i; 
  char* endptr; 

  // start parsing 
  i = 0; 
  i++; 
  humidity = strtod(&packet[i], &endptr);       // next field: humidity 

  while(packet[i++] != ',');			// next field: fahrenheit	 
  fahrenheit = strtod(&packet[i], &endptr); 

  while(packet[i++] != ',');			// next field: celcius 
  celcius = strtod(&packet[i], &endptr);	 

  while(packet[i++] != ',');			// next field: SCPfahrenheit 
  SCPfahrenheit = strtod(&packet[i], &endptr);	 

  while(packet[i++] != ',');			// next field: presure 
  presure = strtod(&packet[i], &endptr);	 

  while(packet[i++] != ',');			// next field: counter 

  while(packet[i++] != '

); // next field: checksum

Serial.print("humidity: ");
 Serial.print(humidity, DEC);
 Serial.print(" fahrenheit: ");
 Serial.print(fahrenheit, DEC);
 Serial.print(" celcius: ");
 Serial.print(celcius, DEC);
 Serial.print(" SCPfahrenheit: ");
 Serial.print(SCPfahrenheit, DEC);
 Serial.print(" presure: ");
 Serial.println(presure, DEC);
}

what are your symptoms - hangup, no data, garbled data? Is the board compatible with 3.3 volt logic on Due?. Are you connected to rx1 and tx1 and you have rx of board to tx of due and visa versa?

Powering the Arduino by USB connection right now. I'm sending 5V from the Arduino to the Weatherboard, and I have the RX-1 from the Weatherboard to the TX1 on Arduino and TX-0 on Weatherboard to RX1 on Arduino. No data being received to the arduino from the Weatherboard.

can the weatherboard communicate at 3.3 volt? if it is using 5v signals it could fry the Due input rx

Weatherboard is suppose to be operated between 3.7-12V

There is a 3.3V regulator within the board to limit voltage
