Unsigned into range is 0-255 so, when i--; and the control reaches while (0>=0 ) conditions will remail true and after that it will again decrease value of zero and due to range it will rotate back to 255. So again 255>=0 ... And so on.. Loop will iterate infinite times.

Explanation:
Since i is an unsigned integer it can never become negative.
So the expression i-- >=0 will always be true, leading to an infinite loop.

The usage of static with a function or variable restricts their scope.Is this behaviour memory related?

jbode

 Profile Answers by jbode Questions by jbode

• Jun 5th, 2019

The static keyword does not affect where or how a function is stored in memory. It only affects whether the function *name* is visible to code outside of the current translation unit (source file).

Harsha

• Mar 27th, 2019

You have to specify where you are going to place it. You can do this in the linker file(.lsl or .ld file). If you place it in the .text section, it goes into the Flash, else by default a static function is placed in the RAM(.data).
