Calling loop() after noLoop() without user input?

Bennie

I am trying to achieve a simple delay function, without using timers. This is needed to call functions in a sequence or in a for loop. It seems that calling noLoop() would be perfect for this, except that you cannot call loop() again after a certain amount of time has passed?

Example: (from Arduino)

loop() {  
  functionOne();  
  delay(100);  
  functionTwo();  
  delay(200);  
  for(int i = 0;i<10;i++) {  
     functionThree();  
     delay(50);  
  }  
}

Why can't you call loop() again after a certain amount of time has passed?

Why are you trying to avoid using a timer?

Can you post an MCVE (not your whole project, but not a disconnected snippet that we can't run)?

How would I call loop() (after the loop is stopped), without user input after a certain amount of time?

This is a code example that executes a different function every 5 seconds. I find it rather unwieldy, and it doesn't work inside a for loop.

int state = 0;
long lastTime = 0;

void setup() {
  lastTime = millis();
}
void draw() {
  if ( millis() - lastTime > 5000 ) {
    switch(state){
      case 0:
        functionOne();
        break;
      case 1:
        functionTwo();
        break;
      case 2:
        functionThree();
        break;
    }
    state++;
    if(state == 3) state = 0;
    lastTime = millis();
  }
}

static final int TIMER = 5 * 1000;  // 5 seconds

void setup() {
  noLoop();
  thread("timer");
}

void draw() {
  print("Triggered\t");
}

void timer() {
  for (;; redraw())  delay(TIMER);
}

Again, why are you trying so hard to avoid using a timer of some kind? That's pretty much the definition of what you're looking for.
