Esp32 Memory Problems in Arduino IDE

Using Arduino Project Guidance
1

Hello,

I've read on this forum that people have had the same problem I am facing now. I followed the proposed solutions and still did not entirely fix my issue. I have already set the Partition Scheme to "HUGE APP (3 MB NO OTA/1MB SPIFFS" as well as lowered the upload speed. This is my first time using an esp32 and my first time using this forum so please have some grace, the program is a simple LED and pushbutton circuit, I appreciate everyone's help greatly. The code and output are as follows:
| CODE

int ledpin= 23;
int buttonpin=15;
int buttonread;
int ledstate=0;
int buttonnew;
int buttonold=1;


void setup() {
  // put your setup code here, to run once:
  Serial.begin(9600);
  pinMode(ledpin, OUTPUT);
  pinMode(buttonpin, INPUT);
  
}

void loop() {
  // put your main code here, to run repeatedly:
  buttonnew=digitalRead(buttonpin);
  buttonread=digitalRead(buttonpin);
  Serial.println(buttonread); // prints 1's when not pressed and 0's when is
  

  if (buttonold == 0 && buttonnew==1) {
    if (ledstate == 0) {
      digitalWrite(ledpin, HIGH);
      ledstate=1;
    } else {
      digitalWrite(ledpin, LOW);
      ledstate=0;
    }
  }
 buttonold=buttonnew;
}

I moved your topic to a more appropriate forum category @epwalker97.

The Nano ESP32 category you chose is only used for discussions directly related to the Arduino Nano ESP32 board.

In the future, please take the time to pick the forum category that best suits the subject of your question. There is an "About the _____ category" topic at the top of each category that explains its purpose.

Thanks in advance for your cooperation.

Hi @epwalker97.

You mention "memory problems". However, the output you shared is of a successful compilation and upload so there is no evidence of a problem.

Please provide a detailed description of the problem you are experiencing.
