[Solved] 'has no member named'

Projects Programming

This is driving me bananas. I swear I have everything set. I'm new to this Arduino thing, but I feel everything is right.

I'm using an example from Sparkfun, but something is missing. Any help is greatly appreciated. I need these weather probes functioning for the big severe weather outbreak tomorrow, and the GPS is my problem.

Using Arduino 1.0.5-r2
Uno R3 Board

I left out all the weather parts of the code which is working fine.

The GPS is connected to the WeatherShield via the serial connector.

Weather Shield: https://www.sparkfun.com/products/12081

GPS Receiver: GPS Receiver - GP-735 (56 Channel) - GPS-13670 - SparkFun Electronics

 This example code assumes the GP-635T GPS module is attached.
 
 */

#include <Wire.h> //I2C needed for sensors
#include "MPL3115A2.h" //Pressure sensor
#include "HTU21D.h" //Humidity sensor
#include <SoftwareSerial.h> //Needed for GPS
#include <TinyGPS.h> //GPS parsing

TinyGPS gps;

static const int RXPin = 5, TXPin = 4; //GPS is attached to pin 4(TX from GPS) and pin 5(RX into GPS)
SoftwareSerial ss(RXPin, TXPin); 

MPL3115A2 myPressure; //Create an instance of the pressure sensor
HTU21D myHumidity; //Create an instance of the humidity sensor



  float flat, flon;
 
// returns +/- latitude/longitude in degrees
  gps.f_get_position(&flat, &flon);
  float falt = gps.f_altitude(); // +/- altitude in meters
  float fc = gps.f_course(); // course in degrees
  float fk = gps.f_speed_knots(); // speed in knots
  float fmph = gps.f_speed_mph(); // speed in miles/hr
  float fmps = gps.f_speed_mps(); // speed in m/sec
  float fkmph = gps.f_speed_kmph(); // speed in km/hr
 
  
  char sz[32];
  Serial.print(",date=");
  sprintf(sz, "%02d/%02d/%02d", gps.date.month(), gps.date.day(), gps.date.year());
  Serial.print(sz);

  Serial.print(",time=");
  sprintf(sz, "%02d:%02d:%02d", gps.time.hour(), gps.time.minute(), gps.time.second());
  Serial.print(sz);

  Serial.print(",");
  Serial.println("#");

}

I'm getting these errors.

Weather_Shield_with_GPS.ino: In function 'void printWeather()':
Weather_Shield_with_GPS:457: error: 'class TinyGPS' has no member named 'date'
Weather_Shield_with_GPS:457: error: 'class TinyGPS' has no member named 'date'
Weather_Shield_with_GPS:457: error: 'class TinyGPS' has no member named 'date'
Weather_Shield_with_GPS:461: error: 'class TinyGPS' has no member named 'time'
Weather_Shield_with_GPS:461: error: 'class TinyGPS' has no member named 'time'
Weather_Shield_with_GPS:461: error: 'class TinyGPS' has no member named 'time'

I defined the TinyGPS library <TinyGPS.h>and included it.

This is in the library

public:
TinyGPSPlus();
bool encode(char c); // process one character received from GPS
TinyGPSPlus &operator << (char c) {encode(c); return *this;}

TinyGPSLocation location;
TinyGPSDate date;
TinyGPSTime time;
TinyGPSSpeed speed;
TinyGPSCourse course;
TinyGPSAltitude altitude;
TinyGPSInteger satellites;
TinyGPSDecimal hdop;

So the Date and Time is already defined.

Thanks for your help,

Hi, what arduino are you using?

Tom.... :slight_smile:

Arduino 1.0.5-r2

I'm using the Uno R3 Board.

I mentioned just about everything but what's important.

The code posted is missing both setup and loop so it will never compile.

But I believe the problem is you're confusing TinyGPS with TinyGPS++. TinyGPS has no date function as you're using it.

For TinyGPS you have to do the following to access the date/time:

int year;
byte month, day, hour, minutes, second, hundredths;
unsigned long fix_age;
 
gps.crack_datetime(&year, &month, &day,
  &hour, &minute, &second, &hundredths, &fix_age);

You then use year, month, day, hour, etc. as you need.

Hope this helps,

YEEEEEEEESSSSSSSSSSSS THAT DID IT!!!!

I forgot to add the "++" back to the mix. You are my hero, thank you so much!

I think we're golden.
