Pin change interrupt not firing with MySensors



  • @Yveaux

    Hey!
    Got some news... the new charge of Arduino Pros arrived, but the problem persists. So I started more trail ' n error and got something:

    I installed the Arduino-IDE and mysensors-1.5.4-library on an manjaro-based notebook. I had to do some symlinking to get a newer version of avrdude working and now the same sketch I used before works now!

    Back to my Mac, flashing the same sketch, the node doesn't work correctly?!
    So problem seems to be the version of avrdude, which is offered by the arduino-ide?!


    I finally downgraded to IDE 1.6.8 and especially AVR Boards 1.6.8.
    Now everything works as expected .... :D

    So it was just a bug in the latest updates of the ide and boards? I'm having probably the same problem on a mega2560



  • @gohan

    I'm not familiar with your problem, but mine was, that the interrupt on pin3 didn't work as expected. So I was not able to use my new sensor as watchdog for my windows/doors. With downgrade of the Arduino-IDE AND especially AVR Boards 1.6.8 my problem is solved now and every change on that interrupt-pin is correctly recognised and send to gateway.

    @idstone if you don't mind, please take a look at last line of my code https://forum.mysensors.org/topic/5807/interrupt-and-sleep



  • @gohan

    Hi again. I can confirm, that I got similar problems... the state of the interrupt pin wasn't correctly recognized, too.
    May be You could try downgrading Arduino-IDE and (very important) avr boards (1.6.8) ?!



  • I'll see if I can find time today or tomorrow to try this. Also might be interesting to see whether it would be possible to get around the issue using Platform.io.


  • Mod

    @idstone
    I'll give it a try maybe on another computer just to be safe



  • @gohan

    any news?



  • I updated my sensors to use v2 of the MySensors library and this issue went away. Used the same board with same fuses and same Arduino IDE and boards file version. Imho this would suggest that there is an issue in MySensors.

    Before migrating to v2 I ran some tests using a button in place of the PIR sensor and it seemed that using a short timeout for the gw.sleep would work, but a longer would not. Did not dig deeper into this though, so might be that it just seemed to work better.

    @idstone

    No, I tried different ways without success and I am waiting for new arduino boards to arrive and start testing from there, probably my MEGA isn't the right platform for these tests



  • So I've returned to this thread after 2 months, as I finally found the time to test the workaround @Yveaux suggested on Januari 8th. In the mean time I had updated my library to the latest version (2.1.1).
    When I run my sketch now, it never goes to sleep. Actually it does, but wakes up immediately. I use int testInt = sleep(0xff, 0x00, 0xff, 0x00, 0);, testInt returns -1, as in; MCU woke by timer. That is both with and without the workaround, and I am not sure that it's caused by the interrupt definitions. Up to 2.0 that worked fine (I rolled back yesterday to try).

    Now I found this other thread where @tekka stated that he corrected some stuff that as out of line with the datasheet for the 328(p).

    So what would be the correct way to make a node sleep forever without using the ExternalInterrupts (INT_0 and INT_1)? I am in no rush to get this going, because my first nodes are going to be mains powered, so they will be happily looping along without sleeping. But as this node has 4 buttons, PinChange is a route I'd like to go.

    (Now I have to go and retract my statements in another thread, because they are null and void now.)

    @DavidZH Can you post your sketch & full debug log?



  • Sure!

    The only funny thing I see is at 2549 !MCO:SND:NODE NOT REG.

    ( I actually just noticed that the setupis run before the presentation. I thought that had been changed)

    edit: I forgot to mention my hardware!
    328p-AU on a custom board on the 8MHz internal clock. The interrupt pins are connected via a RC network (debounce) to the pins with the internal pullups. I used the button.h library because I'm lazy :) it also keeps the code a bit neater to look at.

    @DavidZH IRQ triggers only on LOW level when sleeping (see at328 datasheet) - what happens if you substitute all enableInterrupt(xyz, CHANGE) to enableInterrupt(xyz, LOW)?

    The only funny thing I see is at 2549 !MCO:SND:NODE NOT REG

    this is because you set a 100ms timeout here:

    #define MY_TRANSPORT_WAIT_READY_MS 100 //Start the node even if no connection to the GW could be made
    

    set it to 0 or increase to e.g. 10000...



  • @tekka said in Pin change interrupt not firing with MySensors:

    @DavidZH IRQ triggers only on LOW level when sleeping (see at328 datasheet) - what happens if you substitute all enableInterrupt(xyz, CHANGE) to enableInterrupt(xyz, LOW)?

    That is not true! Chapter 13, page 70, second part, first line: The External Interrupts can be triggered by a falling or rising edge or a low level. For completeness I tried, but the outcome is the same; node wakes up immediately.

    You're right! My bad. I'll change that to 2700, that's the approximate time the node needs to start up.

    @DavidZH

    That is not true! Chapter 13, page 70, second part, first line: The External Interrupts can be triggered by a falling or rising edge or a low level.

    For sleeping MCUs, you may have missed this here:
    http://www.atmel.com/images/Atmel-8271-8-bit-AVR-Microcontroller-ATmega48A-48PA-88A-88PA-168A-168PA-328-328P_datasheet_Complete.pdf

    Chapter 10.1 Sleep Modes (pg 39) => read note 3

    If the node still wakes up, it could be triggered by the radio - this is something we need to investigate further. If you disable all IRQs (on ChanA-D) - does it still wake up?



  • I respectfully disagree: That states only INT_0 and INT_1, I am using PCI. Different mechanism and vectors.

    About the radio waking it up: you mean interference? Or the interrupt? I think those are not the case, as he wake reason states -1, by timer. And if I flash the exact same sketch using the 2.0 library, the node stays asleep properly and wakes with the press of a button.
    The thing I ran into when developing this node was that I could use PCI when using deep sleep, but when I wanted to add a timer to send a sensor value periodically as well, the node would only wake up with the timer, and only then register the interrupt events.


  • Admin

    @DavidZH Now I see, indeed, missed the PCI part - my bad :) Maybe @Yveaux can chip in here?



  • No worries man! We're all learning as we're moving along with this project. And there's so much info in most of the posts that some parts will be missed. Inevitably.


  • Mod

    @DavidZH before I dive into this could you please strip your sketch to the bare minimum that demonstrates the problem (mySensors 2.0.0 vs 2.1.1), preferably without using any hardware connections? Thanks!
