Hello! Im programming an avr microcontroller in pure C at the moment and am close to run out of memory and cycles. So I did some research on optimization. The problem is there are so many articles and hints that do not state the same and do not clearly point out what is valid for pure C. So I'd like to know: - when to use switch instead of else-if statments - how many cases there have to be for switch to be better than else-if? - is an if-if statement better than if-else-if or switch when it is an exclusive decission? - is it better to nest switch statement or use else-if instead of nesting? - does it save RAM when I define variables in the innermost scope possible? - when does it help writing out loops? - should I concider using banned goto instructions for microcontrollers? Thanks for Your answers. Lynx
