accelstepper and watchdog

Postby wanti00 » Thu Jul 02, 2020 3:09 pm

Hi i have a code like this. I am sending step values via mqtt.
İf i dont use disable watchdog then i get crash around step no 100 and if i use watchdog i get error around step no 1300.



ets Jan 8 2013,rst cause:4, boot mode:(3,6)

wdt reset
load 0x4010f000, len 3456, room 16
tail 0
chksum 0x84
csum 0x84

Code: Select all

#include <ESP8266WiFi.h>
#include <PubSubClient.h>
#include <AccelStepper.h>

#define Motor1_Dir 5
#define Motor1_Step 4

const char* ssid = "xxx";
const char* password = "xxx";
const char* mqtt_server = "xxx";
const char* mqttUser = "xxx";
const char* mqttPassword = "xxx";

int value;
bool flag1;

AccelStepper stepper(1, Motor1_Step, Motor1_Dir); 

WiFiClient espClient;
PubSubClient client(espClient);


void setup_wifi() 
{
  delay(10);
  Serial.println();
  Serial.print("Connecting to ");
  Serial.println(ssid);

  WiFi.mode(WIFI_STA);
  WiFi.begin(ssid, password);

  while (WiFi.status() != WL_CONNECTED) 
  {
    delay(500);
    Serial.print(".");
  }
  randomSeed(micros());
  Serial.println("");
  Serial.println("WiFi connected");
  Serial.println("IP address: ");
  Serial.println(WiFi.localIP());
}


void callback(char* topic, byte* payload, unsigned int length) 
{
  Serial.print("Message arrived [");
  Serial.print(topic);
  Serial.print("] ");

value = 0;
  int tensValue = 1;
  for (int i = length - 1; i >=0; i--) // iterate backwards
  {
    value += (payload[i] - '0') * tensValue ;
    tensValue = tensValue * 10;
  }
  flag1 = true;



  
//  for (int i = 0; i < length; i++) 
//  {
//   Serial.print((char)payload[i]);
 // value = (char)payload [length -1];
 //   flag1 = true;
//  }
//  Serial.println();

}


void reconnect()

      client.subscribe("Alkan/perde");
    } 
    else 
    {
      Serial.print("failed, rc=");
      Serial.print(client.state());
      Serial.println(" try again in 3 seconds");
      delay(3000);
    }
  }
}


void setup() 
{
  Serial.begin(115200);
  
  setup_wifi();
  
  client.setServer(mqtt_server, 1883);
  client.setCallback(callback); 

  stepper.setMaxSpeed(200);
  stepper.setAcceleration(100);  
//  stepper.setSpeed(200);    
}



void loop() 
{
  if (!client.connected()) 
  {
    reconnect();
  }
  client.loop();
  {

     if( flag1 ==  true )
        {
//        stepper.enableOutputs();

        stepper.moveTo(value);
        stepper.runToPosition();

That's on an ESP8266, and as this is an ESP32 forum, I'm not sure you'll get the answer you're looking for, sorry.

Suggest trying any support places for Arduino on the ESP8266 then, as you're using that platform.
