Strange Incompatibility when DRD is in a xTask

[DeeJayMX]

Hi, to start thanks for your good good lib.

I need to delegate the DRD in a task to completly separate from loop(), I tried with a xTask but when DEBUG is enabled, the board crash:

Connecting.......Stop doubleResetDetecting
Guru Meditation Error: Core  0 panic'ed (Unhandled debug exception)
Debug exception reason: Stack canary watchpoint triggered (DbleRstCheckr)

If you want to keep debug mode enabled: Just add more space for it with 1500 byte of stack size to the default stack size of a new task. here is my code if you want to publish an example:

Define:

//------------------------------------------------------------Double Reset Detector
#define ESP_DRD_USE_EEPROM      true
#define DOUBLERESETDETECTOR_DEBUG       true  //false
#include <ESP_DoubleResetDetector.h>      //https://github.com/khoih-prog/ESP_DoubleResetDetector

// Number of seconds after reset during which a 
// subseqent reset will be considered a double reset.
#define DRD_TIMEOUT 5

// RTC Memory Address for the DoubleResetDetector to use
#define DRD_ADDRESS 0

DoubleResetDetector* drd;

// For ESP32 LED Builtin
#ifndef LED_BUILTIN
#define LED_BUILTIN       2         // Pin D2 mapped to pin GPIO2/ADC12 of ESP32, control on-board LED
#endif

#define LED_OFF     LOW
#define LED_ON      HIGH
//------------------------------------------------------------Double Reset Detector

Func to declare before setup:

void DoubleResetCheck(void * parameter){
  for(;;){ // infinite loop

drd->loop(); // Double Reset Detector

    // Pause the task for 5ms
    vTaskDelay(5 / portTICK_PERIOD_MS);
  }
}

In Setup():

//------------------------------------------------------------Double Reset Detector
  drd = new DoubleResetDetector(DRD_TIMEOUT, DRD_ADDRESS);
  if (drd->detectDoubleReset()) 
  {
    Serial.println("");Serial.println("Double Reset Detected");Serial.println("");
    digitalWrite(LED_BUILTIN, LED_ON);
  } 
  else 
  {
    Serial.println("");Serial.println("No Double Reset Detected");Serial.println("");
    digitalWrite(LED_BUILTIN, LED_OFF);
  }

    xTaskCreate(DoubleResetCheck,    // Function that should be called
    "DbleRstCheckr",   // Name of the task (for debugging)
    1500,            // Stack size (bytes)
    NULL,            // Parameter to pass
    1,               // Task priority
    NULL             // Task handle
  );
//------------------------------------------------------------Double Reset Detector

Hi @DeeJayMX

Thanks for using the library and your encouraging words. I'll certainly include your novel solution in a new example, and and credit you contribution in next release.

Regards,

[DeeJayMX]

My example is wrote for ESP32 but I think it's convertible for ESP8266 and/or Microcontroler with FreeRTOS... Thanks 👍😁

[khoih-prog]

If possible, please make the complete example for both ESP32 and ESP8266. Then I'll post on the Master repo so that other people can use, without waiting for next release. Thanks,

[DeeJayMX]

I don't have ESP8266 to test...

[khoih-prog]

I can test here if you send the code for ESP8266.
