    See anything wrong with this simple line?

    Hello All,

    I am getting an error with what seems to be very simple. Here it is
    Code:
    if (!GPIO_ReadInputPin(BUTTON_PORT,BUTTON_PIN) && (button_db > DEBOUNCE_TIME))  {    button_press_gf = TRUE; }
    
    The compiler says it is expecting a ")". What am I missing here? I know the function call is ok.

    Yes. It seems fine, doesn't it. I just broke it up like this:
    Code:
     
    if (!GPIO_ReadInputPin(BUTTON_PORT,BUTTON_PIN))    { if (button_db > DEBOUNCE_TIME) button_press_gf = TRUE;    }
    


    It is flagging the error in the inner statement.

    LOL. I just found my stupid error. I ended the DEBOUNCE_TIME definition with a semicolon.

    My guess is you should look at the macro DEBOUNCE_TIME to see whether it has mis-matched ( )

    Also, you can try this
    gcc -E prog.c > prog.i
    prog.i will be the result AFTER the pre-processor has expanded all macros, and included all files.

    Other compilers have a similar option.
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.
    I support http://www.ukip.org/ as the first necessary step to a free Europe.

    That is correct. I had the define line as:

    Code:
     
    #define DEBOUNCE_TIME 30;
    
    Thanks.
