So I`ve been using a simple state design pattern for a xiao esp32c3 chip, and upon uploading the code, my state machine works kinda fine, except the fact that in the first state I get spammed with the following:

(stack memory displays here memory adresses… and then this)

ELF file SHA256: 8a3e19fac03e38d8

This error loops while in the first state, until i write in the serial monitor the input to switch states, which usually works. THe looping with the “Waiting for input” from the first state and the error is asynchronous.

This is my chip.cpp

#include "chip.h"
#include "Arduino.h"
#include <string>

chip::chip()
    : reading_pin(D0), power_pin(D2), pwmFreq(5000), pwmResolution(8), 
     idleState(), pairedState(), genState(), currentState(&idleState){
    

    delayMicroseconds(1000); // Stabilize serial 


    pinMode(reading_pin, INPUT);
    ledcAttach(power_pin, pwmFreq, pwmResolution);

}


void chip::loop() {
    this->performState();
    this->handle(); // checks serial monitor for requests
    //this->printchip();

}

void chip::performState(){
    if (currentState == nullptr) {
        Serial.println("Error: Current state is null.");
        return;
    }
    currentState->perform(this);
}

void chip::handle() {
    if (currentState == nullptr) {
        Serial.println("Error: Current state is null.");
        return;
    }
    currentState->handleRequest(this);

}

void chip::setState(State* newState) {

    if (newState == nullptr) {
        Serial.println("Error: Attempted to set state to null.");
        return;
    }

    currentState = newState; // change states

}

/*
void chip::printchip(){
  currentState->printState();

}*/

And my IdleState.cpp, which inherits from state.h

#include "idlestate.h"
#include "chip.h"
#include "Arduino.h"

void IdleState::perform(chip* esp) {
  

    Serial.println("Waiting for HANDSHAKE input...");
    delayMicroseconds(1000); // Let the user see the message 
}

void IdleState::handleRequest(chip* esp) {
  
    if (Serial.available() > 0) {
        String input = Serial.readStringUntil('n');

        if (input.equals("HANDSHAKE")){
            
            // blink as sucessfull handshake
            for (int i = 0; i < 3; i++) {
                esp->ledWrite(255);
                delay(100); 
                esp->ledWrite(0);
                delay(100);
                esp->ledWrite(255);
                delay(100);
                esp->ledWrite(0);
                delay(100);
            }
            Serial.println("Comms established! Device paired.nWaiting for GEN input");
            esp->setState(&esp->pairedState);
        }
        else{
            Serial.println("Invalid input for current state of the chip");
            return;
        }
    }
    
}
/*
void IdleState::printState(){
  Serial.println("GAGAA");
}*/

So by commenting out functions i found the problem was in the chip’s loop function, and for the error not to happen i had to comment out this->performState() and this->handle(). Even if i commented their bodies, the error would still occur. I tried seeing if this issue was about accessing currentState’s functions,by creating the dummy function “printState()”, and it indeed keeps printing this error. My main.ino file is this:

#include "chip.h"
#include "Arduino.h"



chip babelChip;

void setup(){
    Serial.begin(9600);// BAUD HERE
    babelChip = chip();
}

void loop(){
    babelChip.loop();
}

Keep in mind somehow the state machine works. I’ve tried everything for the last 2 days from debugging with other people to analyzing every line with chatgpt, which makes me think this is either a super niche error or a hardware issue. Any help is greatly appreciated.
