Activitybot C code for qti sensors won't run

Hi
We are having trouble loading code for qti sensors from the Activitybot C code folder (most recent version). We keep getting this error: simpletools.h: No such file or directory. We are using the most recent version of the Learn folder. Does anyone know how we can fix this?

  • Please post your code, preferably between code blocks (click on the "C" in the edit bar and paste your code between them.

    thanks

  • I would seem that where ever you have the QTI library it is outside the SimpleIDE folder.

    It's having a problem finding the base include files.

    THanks. The qti folder is inside the Simple IDE learn folder. One of the qti programmes runs, the one I posted doesn't.
  • When I tried to compile the code above I got a couple of errors.
    The first was the ";" after the function name (line 96 in SimpleIDE).
    int getQTIs(int highPin, int lowPin);
    

    There should not be a semicolon after the function name in the function.

    The next was line 30, the line before the switch statement
    QTIs();
    

    I think this should be
    getQTIs(pin number, pinnumber);
    
    I'm not sure what highpin and lowpin are in your program. I just used 7 and 6 to see if it would compile and it did.
    getQTIs(7, 6);
    

    I did not get an error
    simpletools.h: No such file or directory
    

    My version of SimpleIDE is 1.1.0, and I have the 1/23/18 library update.

    Hope this helps
    Tom
  • Thanks. I will try this.
