Blynk freezes - Soft WDT reset - when working with a stepper motor

Solved
1

Добрый вечер.

Подскажите что доделать, чтобы в момент работы шагового двигателя (30 секунд и более) Blynk не подвисал и не вылетал с ошибкой - Soft WDT reset

Вот часть моего кода:

Good evening.

Tell me what to finish, so that when the stepper motor is running (30 seconds or more), Blynk does not move or fly with an error - Soft WDT reset

Here is part of my code:

BLYNK_WRITE(V0)   // Кнопка
{
  if (param.asInt() == 1 && oldposition == 0) // Проверяе закрывать если было открыто
  {
    oldposition = param.asInt();
    EEPROM.write(0, oldposition); // Записываем в память последнее положение
    EEPROM.commit();

    gostep(1000);
  }

  if (param.asInt() == 0 && oldposition == 1) // Проверяем открывать если было закрыто
  {
    oldposition = param.asInt();
    EEPROM.write(0, oldposition); // Записываем в память последнее положение
    EEPROM.commit();
    gostep(-1000);
  }
}


void gostep (int stepper)
{
  myStepper.step(stepper);
}

Dobro veče i tebi i dobrodošao na forum.

WDT reset je vezan gotovo isključivo za greške u kodu, a da bi do tih grešaka mogli da dođemo, opet moraš da nam daš dovoljno podataka: info o platformi koja se koristi, za početak, i propisno formatiran kod mogli bi dosta da pomognu i tebi, i nama. Uz obaveznu upotrebu engleskog, naravno, kako bi svi mogli da shvatimo o čemu se radi.

Hope that helps a lot!

Platform - Wemos D1 mini
On this Board, stepper motor works fine. But as soon as I connect to Blynk, Blynk hangs. Hangs at the very moment of engine operation

4

Is there something else in void loop except Blynk.run and/or timers? What do you see in Serial monitor when Wemos hangs? Pls paste whole code, it would be much easier.

#define BLYNK_PRINT Serial
#include <EEPROM.h>
#include <ESP8266WiFi.h>
#include <BlynkSimpleEsp8266.h>
#include <Stepper.h>


const int stepsPerRevolution = 64;  //кол-во шагов на оборот
Stepper myStepper(stepsPerRevolution, 14, 12, 13, 15);

char auth[] = "";
char ssid[] = "";
char pass[] = "";

int oldposition; // Поледнее положение: 1 - открыто; 0 - закрыто; BUILTIN горит при закрытом положении.


void setup()
{
  
  Serial.begin(9600);
  Serial.println("Start...");
  pinMode(BUILTIN_LED, OUTPUT);
  digitalWrite(BUILTIN_LED, HIGH);
  EEPROM.begin(4);
  oldposition = int(EEPROM.read(0));  // Читаем значение из памяти о последнем положении
  Blynk.begin(auth, ssid, pass);
  myStepper.setSpeed(300);
}

void loop()
{
  Blynk.run();

}


BLYNK_CONNECTED() {
  //Blynk.syncAll();
}

BLYNK_WRITE(V0)   // Кнопка
{
  if (param.asInt() == 1 && oldposition == 0) // Проверяе закрывать если было открыто
  {
    oldposition = param.asInt();
    EEPROM.write(0, oldposition); // Записываем в память последнее положение
    EEPROM.commit();

    gostep(1000);
  }

  if (param.asInt() == 0 && oldposition == 1) // Проверяем открывать если было закрыто
  {
    oldposition = param.asInt();
    EEPROM.write(0, oldposition); // Записываем в память последнее положение
    EEPROM.commit();
    gostep(-1000);
  }
}

// ************************* //

BLYNK_WRITE(V10)  // Таймер
{
  digitalWrite(BUILTIN_LED, !digitalRead(BUILTIN_LED));

  if (param.asInt() == 1 && oldposition == 0) // Проверяе закрывать если было открыто
  {
    oldposition = param.asInt();
    EEPROM.write(0, oldposition); // Записываем в память последнее положение
    EEPROM.commit();
    gostep(1000);
  }

  if (param.asInt() == 0 && oldposition == 1) // Проверяем открывать если было закрыто
  {
    oldposition = param.asInt();
    EEPROM.write(0, oldposition); // Записываем в память последнее положение
    EEPROM.commit();
    gostep(-1000);
  }

}

void gostep (int stepper)
{

  Serial.print("Steeper go - ");
  Serial.println(stepper);
  myStepper.step(stepper);
  digitalWrite(5, LOW);
  digitalWrite(6, LOW);
  digitalWrite(7, LOW);
  digitalWrite(8, LOW);
}

Ok ? Found quotes :wink:

@atas80 Please format your code in your last post… I already did your first one, your turn now :wink:

@atas80 why did you buy a MAC? Perhaps ask a friend with a PC to format your code.

It has nothing to do with your type of PC… you edit your post above…

And add in the required characters at the beginning and end of your copy/pasted code

11

hack the Stepper.h library to add:

delay(0);

or

yield();

This is actually an image of mac keyboard. Just look closely.

Where exactly write delay (0) Stepper. h?

14

in the cpp file:

  while (steps_left > 0)
  {
    delay(0);
    unsigned long now = micros();

On another note…
You will burn through your eeprom the way you use it :stuck_out_tongue:
It has limited writes. I suggest you try to sync a virtual pin with your “oldposition” instead, and if you are not connected to Blynk then and only then use eeprom instead :stuck_out_tongue:.
Reads from eeprom don’t burn the memory.

if (Blynk.connected()) 
  Blynk.virtualWrite(save_vPin, oldposition);
else
{
    EEPROM.write(0, oldposition);
    EEPROM.commit();
}

You need to work out quirks like which space was saved last as to know which to use of course.
But see this as a hint in a direction :stuck_out_tongue_winking_eye:

17

Got you. Thanks for the hint. In the past, project and working EEPROM. Has been working for a year!

18

A number that pops up is 100,000 write-cycles, whilst that may seem so far away from your code right now,
if you continue that path you might just want to… save a little more… save a little more often … and then… one hot summer day KABOOM! And your device is toast, or atleast its memory :stuck_out_tongue_winking_eye:

So while you are not in any super danger right now I thought I’d just enlighten you ! :slight_smile:

Also for strictly saving values to virtual pins I suggest using those at the far end, if not defined for more then, those at V34-35.
The moment you add widgets that use a virtual pin the save value is nulled, so for storing data best use pins that will not have widgets assigned to them!
