RocketScream Reflow Oven Controller Error compiling

kf9cm

Hi Everyone,

 

I have tried several different IDE's in order to get this sketch to compile, Arduino 1.0, 1.0.5r2 and even .023 and I always get the same error message. I have checked all the line numbers in the error message and they seem to be right.

 

Error compiling

 

In file included from PID_v1.cpp:14:
C:\Arduino\libraries\examples/PID_v1.h:1:1: error: unterminated #ifndef

 

I have tried a lot of Forums, but no one seem to know. I have attached the program file and libraries to this post. If anyone could at least run it on there computer and see if they get the same error message I would be most appreciative. The files has been scanned with Avast and are clean.

 

 

Thank You

 

Gary

  • For that specific problem it looks like simply changing the end of PID_V1.h to this

     

    unsigned long SampleTime;

    double outMin, outMax;

    bool inAuto;

    };  // <-- change here

    #endif

     

    fixes the problem, it then on my computer highlights an issue with the MAX31855 lib but I may have parts missing , I was simply using your supplied code. The change was moving the ";" from after the #endif to the end of the preceding "}"

     

     

    Hope that helps

    Thanks Peter,

     

    I think I have a lot more wrong than just the sketch and libraries. The errors are taking the sketch away from the program folder.

     

    These are the errors:

     

    Reflow_Oven_Controller.cpp.o: In function `__static_initialization_and_destruction_0':
    C:\Users\GARYGI~1\AppData\Local\Temp\build452520561859438296.tmp/Reflow_Oven_Controller.cpp:253: undefined reference to `MAX31855::MAX31855(unsigned char, unsigned char, unsigned char)'
    Reflow_Oven_Controller.cpp.o: In function `loop':
    C:\Users\GARYGI~1\AppData\Local\Temp\build452520561859438296.tmp/Reflow_Oven_Controller.cpp:321: undefined reference to `MAX31855::readThermocouple(unit_t)'

  • Lim over at RocketScream sent me in the right direction.
    It seems that the problem is in the sketch and library. The library file groups  (.h & .cpp) have to be in separate folders labeled MAX31855 and PID_v1.  Then be put in the IDEs main library folder. 
    The INCLUDES in the sketch need  the < > characters  on the *.h files, NOT the " " characters.

     

     

     

    // DO THIS!

     

    // ***** INCLUDES *****
    #include <LiquidCrystal.h>
    #ifdef    USE_MAX31855
        #include <MAX31855.h>
    #else
        #include <max6675.h>
    #endif
    #include  <PID_v1.h>

     

    // NOT THIS!

     

    // ***** INCLUDES *****
    #include <LiquidCrystal.h>
    #ifdef    USE_MAX31855
        #include  "MAX31855.h"
    #else
        #include  "max6675.h"

    #endif
    #include  <PID_v1.h>

    If it works then great, but I have always had the impression that you can put the library files in any folder as long as you include them in the right way, using the Library folder and sub folders is a nice and convent way of managing the code and keeping them separate for maintenance reasons. But if you want to have a project specific set of files and include they do not have to be separated like that as long as there are no conflicting names in the compiler search paths.

     

    But at the end of the day, if it works, who am I to argue

     

    Happy toasting image ( I mean re-flowing)
