granularity of TimerSet_ms differs by 10%

#1 Post by _Cyber_ » 04 Feb 2021, 17:20

Hi,

I am using ESP_Easy_mega_20210114_normal_ESP32_4M316k on a ESP32.

in the following rule I start the event "ControlSZ=0".
It pulses two GPIOs with LongPulse for 28 seconds.
In parallel I start a timer (already with TimerSet_ms as the difference without _ms was bigger), set a variable to 28 and let the timer decrease every second 1 from the VAR#20.

the outcome is that the Pulse of the GPIOs ends and the counter is running nearly 3 seconds longer. :shock:

below also the complete log, following timestamps:
181338027 trigger the event
181339290 Pulse first GPIO
181339295 Pulse second GPIO
181339305 Start timer_ms (VAR#20 already set to 28 before)
181340307 enter the timer-part in rules
181340353 reset the timer to 1000msec (already on most top in the event rule)
181341762 enter the timer-part in rules
181341808 reset the timer to 1000msec
....

a parallel running Rules#Timer=8,1 which is set to 28 Seconds is running out in time and overtakes the periodically reset timer by over 3 seconds:
181339031: ACT : TimerSet,8,28+2
181367032: EVENT: Rules#Timer=8,1
Difference: 28001 (oh, it looks like the addition there does not work - have to rework this)

I have NOT checked SendToHTTP wait for ack

I know, jitter may influence things - but can I do something against it - or to make it more exactly?
Or, as the GPIOPulse is working exactly, is there a way to read in rules the seconds passed from the pulse?

Any ideas? :)

Thanks!

Best regards
Alois


I compared and calculated the differences between the timestamps:

Re: granularity of TimerSet_ms differs by 10%

#2 Post by TD-er » 04 Feb 2021, 18:03

To create repeating timers with at least a repeating interval (jitter is still possible) I created the looptimer
See: https://espeasy.readthedocs.io/en/lates ... oop-timers

Is that usable for your project?
The timer is scheduled based on the last timer + interval, so there should be no drift in the scheduled interval.
Still there can be some jitter in the moment the timer is handled as rules processing can be delayed by blocking code.
I don't think you should try to process several events a second as the rules processing may take some time.
I would really be surprised if you manage to process over 5 events a second.

Thanks, will try looptimer. Looks like it is an alternative.

:!: awesome :!:

with looptimer the difference between the 28seconds (not ms) timer and the looptimer,1000,28 is ... 1ms. :D

the timerpart of the rules is now also shorter with looptimer:

Code: Select all

on Rules#Timer=7 do
 //[VAR#20] seconds requested; [VAR#21] direction; [VAR#22] shutter percent
 logentry,%eventvalue2%
 Let,22,[SZ#S]+(100/28)*[VAR#21]
 if %eventvalue2% = [VAR#20] or [VAR#20] = 0
  if %eventvalue2% != 0
   TimerSet_ms,7,0
  endif
  Let,20,0
  Let,21,0
  TaskValueSet,1,1,[INT#22]
  TaskValueSet,1,2,0
 else
  TaskValueSet,1,1,[VAR#22]
 endif
 SendToHTTP,192.168.0.250,80,/apcucollector.php?smartswitch=%sysname%&SZ=[SZ#M];[SZ#S];
endon
Two questions regarding: "I don't think you should try to process several events a second as the rules processing may take some time. I would really be surprised if you manage to process over 5 events a second."

Does this thinking fit to a ESP8266 or a ESP32?
With ESPEasy, does the ESP32 use both cores? By default (so if not set specificly) with Arduino it uses AFAIK the second core for Wifi stuff - is this also true with ESP32?

I have not checked "Enable RTOS Multitasking" - I do not know what it does, but I suspect it is maybe related. :-)

I have recognized the ESP32 has much more load printed on the main page as my ESP8266 - about 15% compared to 7% on nearly idling around. the shutter-project-ESP32 ist always over 21%, I could save already 10% by combining dummydevice events with "Single event with all values".

Re: granularity of TimerSet_ms differs by 10%

Well those questions do look "simple to answer", but they aren't...

Currently we don't use the 2 cores of the ESP32 as data synchronization is a bit hard between them.
So therefore I disabled it for now and indeed it has to do with RTOS multitasking.
You can of course use locks to sync data between cores, but a lock is rather overkill as it affects both cores.
So a more simpler approach should be to use simple boolean like semaphores, but I ran into some issues which I could not solve very easily, so I left it for later in the hope the core libs would give some better examples later.

The load on ESPEasy is not as easy to explain as one may think.
I have written a scheduler for ESPEasy which also makes sure your loop timer is executed at the right time :)

For this scheduler, every loop() cycle it looks at the next thing to do and checks if its timer has already passed.
If it has, it will pop it from the queue and execute it. => Active loop
If the timer has not yet passed => idle loop.

2 counters are used to keep track of the number of usec is spent in active loop and in idle loop.
This ratio is the "load"

Now the catch...
During "idle loop" the background tasks are also processed.
These can take almost no time, but may also trigger some actions and may take some time to fetch all received WiFi data for example.
(the background tasks are also called every now and then even if there is an active loop ready to run to make sure background tasks are still dealt with)
This may lead to some skew in reported load.

So you can only compare loads on the same platform units.
A load of ESP8266 and ESP32 cannot be compared very well as background tasks may be relative high load for a faster ESP32 as they still take the same amount of time to process.
