Dayadjustment

Blynk_Coeur · October 14, 2018, 2:13pm

hi !

I’m having an issue each Sundays

my serial monitor :
sunday
ayadjustment 6

Exception (28):
epc1=0x40211674 epc2=0x00000000 epc3=0x00000000 excvaddr=0x00000004 depc=0x00000000
ctx: cont 
sp: 3ffffcc0 end: 3fffffd0 offset: 01a0
>>>stack>>>

3ffffe80:  00000000 3ffffee0 3ffffee0 4020ea3f

now, I 'm sure it is only when dayadjustment= 6

BLYNK_WRITE(V100) {   // Scheduler #1 Time Input widget
   if (weekday() == 1) {
    dayadjustment =  6; // needed for Sunday, Time library is day 1 and Blynk is day 7
    Serial.println("sunday");
    Serial.println(dayadjustment);
  }

  TimeInputParam t(param);
  nowseconds = ((hour() * 3600) + (minute() * 60) + second());
  startseconds = (t.getStartHour() * 3600) + (t.getStartMinute() * 60);
  stopseconds = (t.getStopHour() * 3600) + (t.getStopMinute() * 60);


  if (t.isWeekdaySelected((weekday() + dayadjustment))) {
    if (nowseconds >= startseconds && nowseconds <= stopseconds) {
      Timer1 = true;
      Blynk.virtualWrite(V114, 255);  // turn on virtual LED
    }
    else {
      Timer1 = false;
      Blynk.virtualWrite(V114, 0);    // turn OFF virtual LED
    }
  }
  else {
    Timer1 = false;
    Blynk.virtualWrite(V114, 0);   // turn OFF virtual LED
  }
}

same issue with

if (t.isWeekdaySelected((7))) {
    if (nowseconds >= startseconds && nowseconds <= stopseconds) {
      Timer1 = true;
      Blynk.virtualWrite(V114, 255);  // turn on virtual LED

I believe the problem is here. If your code has been running for more than a week and you don’t have an else statement “zeroing” the dayadjustment… Down the line, lets say the following Monday:

t.isWeekdaySelected((weekday() + dayadjustment) = 2+6 = Crash.

Blynk_Coeur · October 15, 2018, 6:20am

thank you for your help @ldb
it will be right if I never have
if(weekday ()==1)
and I restarted nodemecu 15 times yesterday.
today is Monday, all runs well.

Blynk_Coeur · October 15, 2018, 7:01am

@ldb

the same issue if I use “7” instead of weekday

if (t.isWeekdaySelected(7)) {

ldb · October 15, 2018, 7:39am

Well hard to tell. I use somthing very similiar and works fine.

If you do something like:

if (t.isWeekdaySelected(7))  serial.println("I'll print");

does it crash? It may be crashing somewhere else.

Blynk_Coeur · October 15, 2018, 7:56am

I’ll try now , give me 5 minutes

Blynk_Coeur · October 15, 2018, 8:20am

today, there is no issue with t.isWeekdaySelected(7)

I think I have to wait till next sunday and explore where is the bug.
there is necessarily a relationship between t.isWeekdaySelected(7) and the real time clock

Blynk_Coeur · October 15, 2018, 8:23am

thank you @Gunner
it is more readable now

Gunner · October 15, 2018, 9:14am

I was going to try running it through the stack trace decoder… but I can’t figure out how to run the decoder

PeteKnight · October 15, 2018, 9:14am

Maybe the map() function would be a better way of translating time library days into Blynk days, or vice versatility?

Pete.

Blynk_Coeur · October 15, 2018, 9:52am

very interresting tool but I think I’m a noob

Please see:

  /// TimeLib format 1 = Sun . 2 = Mon . 3 = Tue . 4 = Wed . 5 = Thu . 6 = Fri . 7 = Sat ///
  /// Blynk is       1 = Mon . 2 = Tue . 3 = Wed . 4 = Thu . 5 = Fri . 6 = Sat . 7 = Sun ///
int dayadjustment = -1;
 if(weekday() == 1){
  dayadjustment = 6; // needed for Sunday, Time library is day 1 and Blynk is day 7
  }
  if(t.isWeekdaySelected((weekday() + dayadjustment))){  //Time library starts week on Sunday, Blynk on Monday
...

alternatively you can use:

char* WeekDays[8]={"Not", "Mon", "Tue", "Wed", "Thu", "Fri", "Sat", "Sun"}; /// TimeLib format 1 = Sun, 2 = Mon ... ///

thanks @PeteKnight
but how can I use map() function with time library ?
I have no issue with the real time

PeteKnight · October 15, 2018, 10:48am

You’re using if statements based on the time library plus an adjustment. Rather than doing that, map time library days to Blynk days and base your if statements on Blynk days.

Pete.

Blynk_Coeur · October 15, 2018, 2:49pm

to test the code, I would like to change the RTC date with rtc.setDay (day byte) (Sunday instead of Monday)
unfortunately, I have an error: ‘class WidgetRTC’ does not have a member named ‘setDay’

I guess WidgetRTC can not support this function

Blynk_Coeur · October 15, 2018, 3:52pm

I change blynk server date to sunday 14

17:57:29.421 -> weekday 1
17:57:29.421 -> sunday
17:57:29.421 -> dayadjustment  6
17:57:29.455 -> weekday  + dayadjustment  7
activetoday1

17:57:29.901 -> Exception (28):

Blynk_Coeur · October 15, 2018, 4:07pm

I went around the problem,
since Saturday and Sunday is the weekend,
Sunday will be day 6 too
I don’t care, but if anyone can explain to me why there is a problem with sunday, please do …

if (weekday() == 1) {
    dayadjustment =  5; 
    }

mikekgr · October 16, 2018, 3:56am

Please give us a code snippet to see how this can be implemented. Thanks.

Blynk_Coeur · October 16, 2018, 6:29am

thank you @mikekgr
let me tell you that this skech run from monday to saterday , and crash a 0h01 on sunday
since I decided to modify by :
if (weekday() == 1) {
dayadjustment = 5;
there is no issue.

//**************** TIMER 1 ***********************
BLYNK_WRITE(V100) {   // Scheduler #1 Time Input widget
  Serial.println("timer1");
  Serial.print("weekday ");
  Serial.println(weekday());

  if (weekday() == 1) {
    dayadjustment =  5; // needed for Sunday, Time library is day 1 and Blynk is day 7
    Serial.println("sunday");
    Serial.print("dayadjustment");
    Serial.println(dayadjustment);
  }

  TimeInputParam t(param);
  nowseconds = ((hour() * 3600) + (minute() * 60) + second());
  startseconds = (t.getStartHour() * 3600) + (t.getStartMinute() * 60);
  stopseconds = (t.getStopHour() * 3600) + (t.getStopMinute() * 60);


  if (t.isWeekdaySelected((weekday() + dayadjustment))) {
    Serial.println(weekday() + dayadjustment);
    if (nowseconds >= startseconds && nowseconds <= stopseconds) {
      Timer1 = true;
     Blynk.virtualWrite(V114, 255);  // turn on virtual LED
    }
    else {
      Timer1 = false;
      Blynk.virtualWrite(V114, 0);    // turn OFF virtual LED
    }
  }
  else {
    Timer1 = false;
    Blynk.virtualWrite(V114, 0);   // turn OFF virtual LED
  }
} 

//**************** TIMER 2 ***********************
BLYNK_WRITE(V102) {   // Scheduler #1 Time Input widget
  Serial.println("timer2");
  TimeInputParam t(param);
  nowseconds = ((hour() * 3600) + (minute() * 60) + second());
  startseconds = (t.getStartHour() * 3600) + (t.getStartMinute() * 60);
  stopseconds = (t.getStopHour() * 3600) + (t.getStopMinute() * 60);

  if (t.isWeekdaySelected((weekday() + dayadjustment))) {
    if (nowseconds >= startseconds && nowseconds <= stopseconds) {
      Timer2 = true;
      Blynk.virtualWrite(V115, 255);  // turn on virtual LED
    }
    else {
      Timer2 = false;

    }
  }
