Thread: 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.

Are you sure that this line has the error?It seems 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.

There are no stupid errors.You just did not notice it

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.

That is correct. I had the define line as:

Code:

 
#define DEBOUNCE_TIME 30;

Thanks.
