error: multiple definition of 'function' - when I use other libraries

Projects Programming
1

Hi,

I have write a code some time ago for a 16x2 LCD display to be able to see variables from my programs.I've tested using a BMP085 preasure sensor and everything went well at that time. In the mean time I've changed the computer installed Arduino. I've copied the LiquidCrystal library for BMP085 in place of the default library of Arduino (same I've done last time).

Now if I compile the same code I get multiple errors like the one bellow ( for all HMI member functuions used in the code):
HMI\HMI.cpp.o: In function HMI::RefreshValue()': C:\Users\Cristian_Sandor\Documents\Arduino\libraries\HMI/HMI.cpp:162: multiple definition of HMI::RefreshValue()'

I have HMI.h where I have the declaration of HMI class which is derived from LiquidCrystal class.
I have HMI.cpp which contains the implementation of the HMI function members
And finaly I have HMIDev.ino where is the main code.

My gues is that I do not call the #include correctly HMI.h and LiquidCrystal.h files. Please see bellow how I've done it:

//In HMI.h file I have
#ifndef HMI_h
#define HMI_h
#include <Arduino.h>
#include <Wire.h>
#include <LiquidCrystal.h>
class HMI :public LiquidCrystal
{
...
};
#endif
//In HMI.cpp file I have:
#include "HMI.h"
...
code
...
// In the HMIDev.ino I have:
#include <LiquidCrystal.h>
#include <Wire.h>
#include <BMP085.h>
#include <HMI.h>
// .. code

I have tried to remove the line #include<HMI.h> in the HMI.cpp but than give's me multimple errors: error: '... ' has not been declared
Could you please suggest what to do to correct this error? I remember that when I've write initially the code I have had the same issue, and I've meet with this also in other cases but I was able at the end of the day to sort it out. This time, it seems I can't get on with it.
If is useful I can share the hole code file.

Thanks,

FIrst you need to insert The Full code to varify it.

Checkout version Of IDE used in earlier and New PC

The full code is attached.
LiquidCrystal folder is the library which I've used to replace the default one in Arduino\Libraries folder.

The version used initially was Arduino 1.0.5 and now I see it was upgrade to 1.0.5. r2. I still have version 1.0.5. and I've just try to compile the code with it but I have the same error message.

Thanks,

I am asking the code WHich your uploading.The code you attached Incomplete. USe code TAg symbol to paste your code.
i.e # symbol while replying

I did not upload the code in the Arduino as I wasn't able to compile it. The code I've attached is the full folder with INO file and the libraries I use.

Can I provide other information?
Thanks

The issue was resolved using other resources..
Thanks for support
