Error example simple button with interrupt in ESP32.

[oriaj3]

Hi, I am testing the library to include it in a larger project and replace my rudimentary library to use short press and long press on various buttons. But after compiling and uploading the example code to my ESP32 with VScode, I get this error. I use the single button example with interrupt and my ESP32 is made by doit, esp-wroom-32 devkit v1.

#include <Arduino.h>
#include <EasyButton.h>

const uint8_t BOTON_ONOFF=23;

#define BAUDRATE 115200

// Instance of the button.
EasyButton button(23);

void IRAM_ATTR buttonPressed()
{
  Serial.println("Button pressed");
}


void IRAM_ATTR buttonISR()
{
  button.read();
}

void setup()
{

  // Initialize Serial for debuging purposes.
  Serial.begin(BAUDRATE);

  Serial.println(">>> EasyButton interrupts example <<<");

  // Initialize the button.
  button.begin();

  button.onPressed(buttonPressed);

  if (button.supportsInterrupt())
  {
    button.enableInterrupt(buttonISR);
    Serial.println("Button will be used through interrupts");
  }
}

void loop()
{
  // put your main code here, to run repeatedly:
  void(10);
}

Button pressed

Hi!

I think your error is on this:

void loop()
{
  // put your main code here, to run repeatedly:
  void(10);
}

The ESP32 internal Arduino implementation feeds the watchdog timer each time a loop function is called, so that exception is because the watchdog timer was triggered for a timeout.

So remove the void(10) code and try again.

Same error, even without void(10)：
Guru Meditation Error: Core 1 panic'ed (Interrupt wdt timeout on CPU1).

Same error here:

Looks like the Watchdog timer is triggering, The error backtrace is logged below
