Interrupt and sleep

[gohan]

Similar but not the same since I don't have crashes, just it is just ignoring interrupt and sleeping 10 seconds every time.

[mfalkvidd]

@gohan seems like we aren't reading the same thing. I don't see anyhing about a crash, only about interrupt not firing.

[gohan]

Are you referring to the sleep(0xff,0x00, 0xff, 0x00, 0)?

[mfalkvidd]

@gohan no. I am referring to "For some reason I am unable to get the board to respond to pin change interrupts when using MySensors gw.sleep() using the MotionSensor.ino" in the first post in the thread I linked to.

[elysion]

From your description it sounds like your problem is pretty much exactly same as mine was when I started that thread. I have not experienced any crashes. The issue is just that the board does not wake up on CHANGE. Have you tried using LOW instead of CHANGE for sleep? There were comments in the aforementioned thread that this might be an issue with a certain version of Arduino and boards file. Have not yet had time to investigate tough.

[gohan]

@elysion
I have updated IDE to latest version and I got a change: now it takes a variable time between 30 sec to 2 minutes for the motion sensor to restore to "0" .
If I set it to LOW it just skips the sleep as I see continuously errors from reading from the DHT11 sensor until I trigger the motion sensor. Changing it to HIGH or CHANGE I get the same result. Now it's late, so maybe tomorrow I'll try downgrading IDE and boards to 1.6.8 as suggested in another thread.

[gohan]

Downgraded to 1.6.8 IDE and boards but no change, also tried to compile it in Visual Studio but behavior is the same. Maybe the Mega has some issues that other boards don't have?

As you can see when motion is triggered (the "1" on 5th line) it takes a while for it to go back to "0" and each message is 10 seconds from the previous like it is ignoring the interrupt.
I'm running out of options besides buying a few Pro Mini and start building a definitive sensor

[sundberg84]

@gohan - any change if you try to change the trigger delay on the motion sensor?

[gohan]

No, I tried to move it around but it doesn't change the behavior in this case.

[JoergP]

ahhhhhhhhhhhh - I created a door/window sensor some weeks ago - but I couldn't make it run to fire an interrupt on pin change (INT0 and INT1 are used to connect external magnetic sensors) - today I decided to work on this issue again and found this topic at the forum - so I downgraded my arduino IDE by downloading v1.6.8 from arduino.cc today - compiled my code again - falshed it - and voilà - it works
That is really frustrating by wasting that many hours of time only by inconsistancy with compiler/board definitions.
Is there any need to update to newer arduino-IDE - otherwise I would recommend to general stick to one version ...

[gohan]

@JoergP
Would you mind posting board version you are using and also your code? Did some test but I couldn't figure out anything on my mega so probably there is also something about that kind of board, so I didn't spend too much time on it and wait for the other minis I ordered

[JoergP]

I checked the used versions - as I already wrote the used arduino-IDE is 1.6.8. But due to the case that I used 1.8.0 before and downgraded the board definition by "Board manager" the board definition is 1.6.11 (if you down/upgrade by BoardManager you can find the files in dir "C:\Users...\AppData\Local\Arduino15\packages\arduino\hardware\avr\1.6.11"
I added my own definitions to board.txt (because I use 2AA Battery node -> https://www.openhardware.io/view/10/My-Slim-2AA-Battery-Node)

here my quick and dirty source - have to clean up if it works as expected:

[gohan]

What does this do?
wdt_enable(WDTO_8S);

[gohan]

Tests so far are just as the same as before even with the changes you suggested, so I believe I'll just wait for the other new arduinos and use the mega for other purposes

[JoergP]

That's bad - if you like you can send me your source and I can try to compile it on my environment.
I use the watchdog in general - in the past I had the issue that some nodes stopped working without any reason - watchdog helped to solve this

[gohan]

Look at my first post, that's the code. It's a draft so it's not really cleaned up

[Efflon]

@JoergP ans others, I have tried versions 1.6.8 and the board definitions 1.6.11 and interrupt seems to work but in the case of using a PIR the sensor somehow seems to be triggered when going out of sleep due to time...

[JoergP]

@Efflon I'm not sure what exactly you mean - do you refer to my code? In that case this is a quick and dirty try - I'll send at every pin change and at timeout the input values ...

[gohan]

My mega goes to sleep for the time specified, but it doesn't wake up when pir is triggered

[Efflon]

@JoergP Sorry, what I meant was regarding the versions you were using to get your sensor to work. I've been fighting to get interrupts to work for a day and your suggestion helped.
Now it's just that going out of sleep triggers the PIR, then it goes for sleep and wakes up immediately and then finally goes to sleep ... gahh
