  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.
