C language loop question

lau1247

I have a function call "Start" for a start button (physical button) and another function call "Stop" for a stop button (physical button also)..

I need to create a loop that keep on running "Start" once I pressed it until the stop button is pressed which then it must use the "stop" function..

My problem is how do I implement the stop function?
Bcoz to implement it that means I have to manually enter a line into the loop to call the function.. I'm outta ideas..

Anyone? Any help appreciated.. thanks in advance

Set a boolean when you press Stop, and check it during your general loop. Something like:

unsigned short StopPressed = 0;

void MainLoop() {
    while (!StopPressed) {
        doStuff();
        doMoreStuff();
        etc();
    }
    doStopStuff();
}

void StopButtonPressFunction() {
   StopPressed = 1;
}
