Why my function is not calling within a case

2

because you have a // commenting out the call at the start of the line.. don't you?.... I can't really see...

You realize this is probably the dumbest question of the day, right? how can we know if we don't see your code....

here is a working example. are you using switch/case the right way?

void f1()
{
  Serial.println(F("in function 1"));
}

void f2()
{
  Serial.println(F("in function 2"));
}

void f3()
{
  Serial.println(F("in function 3"));
}

void setup() {
  Serial.begin(115200);
  
  byte n = 1;

  switch (n) {
    case 1:
      f1();
      break;
      
    case 2:
      f2();
      break;
    
    default:
      f3();
      break;
  }
}

void loop() {}
