Hi Guys,

I have sketch upload it in my ESP8266 NodeMcu and after code running around 3 to 5 min then the NodeMcu restart and after I decoded the exceptions code I got this result:

User exception (panic/abort/assert)
Panic core_esp8266_main.cpp:188 loop_task

and my sketch code is:

int SetPoint = 30;
int C = 24;

void setup() {
  Serial.begin(115200);
  pinMode(LED_BUILTIN, OUTPUT);
  digitalWrite(LED_BUILTIN, HIGH);   // turn the LED on (HIGH is the voltage level)
  delay(2000);
  digitalWrite(LED_BUILTIN, LOW);   // turn the LED on (HIGH is the voltage level)
}

void loop() {
  ModeOne(0);
}

void ModeOne(float OutputModeOne) { //This Mode To Increase Hot Water Flow
  while (OutputModeOne <= 180) {
    delay(200);
    if ((C - SetPoint) < -3) {
      OutputModeOne = OutputModeOne + 90;
      if (OutputModeOne > 175 ) {
        OutputModeOne = 175;
      }
      ModeTwo(OutputModeOne);
    }
  }
}

void ModeTwo(float  OutputModeTwo) {
  while (OutputModeTwo >= 0) {
    delay(200);
    if ((C - SetPoint) < -3) {
      OutputModeTwo = OutputModeTwo - 90;
      if (OutputModeTwo < 5 ) {
        OutputModeTwo = 5;
      }
      ModeOne(OutputModeTwo);
    }
  }
}

But I don't know what is the issue here is it in my code or from IDE it self!

anyone help me please?

Thanks for all :-)

around 3 to 5 min

Maybe the time needed, with your delays, to fill the stack.
Do your recursive calls ever get out from the initial ModeOne(0) ?

Thanks for reply to me :)

yes the code start from ModeOne(0) !

Do you mean need a delay?

@smartkodian your recursion doesn't end or is too deep, it goes back and forth (slowly) until the ESP runs out of stack.
Closing due to user error.
