Can't detect Interrupt on Arduino Mini Pro or can't wake MySensor ?



  • Hi everybody,

    I spent several time trying to detect interrupt on arduino mini pro 3.3v 8mhz with Atmega328 with button but without success. I tryed to downgrade compiler in 1.6.9 but it doesn't work neither.
    If i remove sleep function it's working, but i need sleep because it a battery node for the mailbox...

    Each time i press the button, i can read that in the log in the serial monitor :

    2369 MCO:SLP:MS=0,SMS=0,I1=0,M1=1,I2=255,M2=255
    2375 MCO:SLP:TPD
    2377 MCO:SLP:WUP=0
    2379 MCO:SLP:MS=0,SMS=0,I1=0,M1=1,I2=255,M2=255
    2383 MCO:SLP:TPD
    2385 MCO:SLP:WUP=0
    2387 MCO:SLP:MS=0,SMS=0,I1=0,M1=1,I2=255,M2=255
    2394 MCO:SLP:TPD
    

    But nothing else.

    Could someone helping me ?

    Thx,
    Ghislain

    This is my code :

  • @ghislain Am I missing something? I don't see anything having to do with an interrupt, just 2 debouncers. An interrupt would use attachInterrupt() and call an ISR (Interrupt Service Routine) which is a separate function in your sketch that would get called when the button gets pressed. On the Pro Mini boards, only pins 2 and 3 can be tied to interrupts, which is the two pins you are using. What did you want the interrupt to do?

    @ghislain your node is waking up. To understand the log, select the "Build" menu item on this website, and chose "Log Parser" in the left column, then you can paste the log and get some full text descriptions of what is happening.

    Do not use debouncer if you are using sleep, instead at the beginning of the loop() method (so it will be called just after the sleep() ends) use a wait(value in ms) command that is long enough to allow the bouncing of the button to finish. Then you can just read the value of the input.

    You also have a problem with your sleep function, you are setting only interrupt 0 (the one that triggers the wake up in your log) but interrupt 1 is not set so the second button will not work.

    @dbemowsk said in Can't detect Interrupt on Arduino Mini Pro or can't wake MySensor ?:

    @ghislain Am I missing something? I don't see anything having to do with an interrupt, just 2 debouncers.

    It's called by the sleep function of MySensors that he calls at the end of his script.



  • Thank you both for your answer.

    To resume what i want to do, i want to watch when mail is arrived in my outdoor mailbox, i will do that with 2 "door sensor".

    @Nca78 if i well understood that you say, interrupt was catched and wake up arduino but value1 (the status of the "door sensor") wasn't updated and so my code doesn't do anything and it fall asleep again. Is that correct ?

    I know, i just have one interrupt else i'm using 2, but it was for test with one firstly.

    I will try to do in another way as you say.

    thanks



  • This is my change and it is working, thank you for your help.
