Pin change interrupt not firing with MySensors
-
Hi!
I have been working on building motion sensors with MySensors to be able to trigger events on my Vera. Earlier I was able to get a few sensors working using 3.3V 8MHz Pro Minis. Now I am trying to build one with a custom ATMega328 board that uses the internal RC oscillator. 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. I debugged the issue with a Pro Mini that (afaicr) is also using the internal oscillator instead of the external oscillator on the board. Everything however works correctly if I do not include MySensors code in my sketch and use attachInterrupt with mode set to CHANGE:
void setup() { Serial.begin(115200); Serial.println("Boot"); pinMode(3, INPUT_PULLUP); attachInterrupt(digitalPinToInterrupt(3), handler, CHANGE); } void loop() { } void handler() { Serial.println("foo"); }However if I pass LOW mode to gw.sleep, the interrupt seems to work and a message seems to be sent to the controller correctly. But of course this only happens when the pin is in LOW state and not on changes.
Has anyone got a clue on what might be causing the issue? I read through the interrupt handling code in MySensors that I believe is relevant in my case (MyHwATMega328 class), but was unable to find anything that might cause the issue.
edit Forgot to mention, but I am using version 1.5 of MySensors /edit

Hello,
for the moment you can't use pin interrupt change lib with mysensors.
Also, note, pinchange need you handle the change state. these are not working like D2/D3 INT0/1.
I'm using pinchange with mysensors, but i use raw registers, my own isr for interrupts, and my sleep function.- for this you can have a look at how pinchange works here http://gammon.com.au/interrupts
- or you can also OR your different pins with diodes
-
Thanks for the reply scalz!

I'm not sure what you mean by "pin interrupt change lib", but I would assume it would be possible to use the CHANGE type when calling gw.sleep as in the examples: https://github.com/mysensors/MySensors/blob/59550410a3f55f11b39aacfcaaa2dd8926682673/libraries/MySensors/examples/MotionSensor/MotionSensor.ino#L64

I'm using pinchange with mysensors, but i use raw registers, my own isr for interrupts, and my sleep function.I have only connected the one motion sensor to my board and the interrupt handler just sends the current state (tripped / not tripped) to the controller. Thus I do not think I need to do anything special here.
To clarify, I am using the MotionSensor.ino code without any modifications on my board. The execution reaches the gw.sleep call without problems, but does not resume even if the pin state changes. I am able to read the value from the pin by setting SLEEP_TIME to 1000 and this way confirm that the value of the pin does change and that can be read correctly.
-
okay!
you're right, i misread because of the title "pin change" lol . So you're using D3, clear
quickly checked the lib, but i don't see anything fancy for the moment. if i find time, perhaps i'll try to reproduce but i've not heard others having this issue. Do you have this problem without doing any changes in the Motion sketch?
-
What I am currently uploading is the unmodified version of MotionSensor.ino linked above. I have previously build a motion sensor using a 3.3V pro mini with the same code. The only difference that I can think of with my current setup is that I am using the internal RC oscillator instead of the external and have changed the fuses accordingly by using the bootloader upload in Arduino IDE. I used the following board configuration:
atmega328PstandaloneInt8MHz.name=Standalone ATmega328P (ATmega boot, internal 8MHz) atmega328PstandaloneInt8MHz.upload.tool=arduino:avrdude atmega328PstandaloneInt8MHz.upload.protocol=arduino atmega328PstandaloneInt8MHz.upload.maximum_size=30720 atmega328PstandaloneInt8MHz.upload.maximum_data_size=2048 atmega328PstandaloneInt8MHz.upload.speed=57600 atmega328PstandaloneInt8MHz.bootloader.tool=arduino:avrdude atmega328PstandaloneInt8MHz.bootloader.low_fuses=0xE2 atmega328PstandaloneInt8MHz.bootloader.high_fuses=0xDA atmega328PstandaloneInt8MHz.bootloader.extended_fuses=0xFD atmega328PstandaloneInt8MHz.bootloader.unlock_bits=0x3F atmega328PstandaloneInt8MHz.bootloader.lock_bits=0x0F atmega328PstandaloneInt8MHz.bootloader.file=atmega/ATmegaBOOT_168_atmega328_pro_8MHz.hex atmega328PstandaloneInt8MHz.build.mcu=atmega328p atmega328PstandaloneInt8MHz.build.f_cpu=8000000L atmega328PstandaloneInt8MHz.build.board=AVR_PRO atmega328PstandaloneInt8MHz.build.core=arduino atmega328PstandaloneInt8MHz.build.variant=standard```

Hi.
Perhaps I ran into a similar issue?
I created a new node with older 1.5.x version of my sensors-library.
But I was not able to get a door-contact working via interrupt on pin 3 with a sketch I used more than 5 times before.
Last change I can remember, was updating Arduino IDE for MacOS Sierra....How can I get back a working interrupt controlled door-switch?!
-
@idstone: Have you tried passing another mode (e.g. LOW) to gw.sleep method? The issue I am having is that with LOW the interrupt fires, but with CHANGE (which is the default in the sketches) it does not.
-
@elysion Issues were fixed in the 2.1 beta of the MySensors library, so you'd better have a look at this code to see how to wake from interrupt.
Furthermore, you're using the ATmega out of spec when trying to wake from CHANGE; see http://forum.mysensors.org/topic/250/how-do-i-use-the-interrupt/5
-
Hi. It seems, that the problem is related to complete charge of my 3,3V arduino pro's.
Reaction on interrupt while closing a door-switch on pin 3 works on an older 5V arduino.
I've read about problems at a customer-evalutation (amazon), especially with arduino pro clones and their interrupt-function.
Bought some more over store from mysensors on ebay... hope these will work correctly

@Yveaux
https://www.amazon.de/Aukru-Redesign-atmega328-ATmega128-Compatible/dp/B00PLD3E1S5.0 von 5 SternenWunderbar!
Von Ludwig Enfield am 19. Juli 2015Bei den Arduino Remakes gibt es immer wieder kleine Abweichungen im Pinout. Also aufpassen - das betrifft hier insbeondere die Interrupt-Pins 0 und 1 bzw. die Pins A6/A7 (u.a. Analog-Ports).
-
@idstone thanks!
If I understand it correctly, the feedback states the pinout of arduino pro mini clones is often slightly different, especially on interrupt pins and analog.
For analog pins this is certainly true, for interrupt pins I have not experienced this myself (yet).
-
In one sketch I am using pin change interrupt. But that is a node I built from scratch. I have the feeling the issues arise with the MyS function "sleep()" in combination with a set time. As long as I call
sleep(0xff,0x00, 0xff, 0x00, 0);
pin change interrupts work. As soon as I change any of the parameters, the node will not wake up anymore.That was on 2.0 I have yet to convert and try it on 2.1.
As soon as I have done that, I will post the code .
-
@DavidZH Just a shot in the dark, but could you try @tekka workaround from https://github.com/mysensors/MySensors/issues/725 and see if it still crashes ?
-
@Yveaux I will try that as soon as I'm back from my winter sports vacation (as far as you can call lush green Alpine meadows that. At least the slopes are well maintained!). I have no access to a node and gateway now.
For me it worked for that sketch as it's main function is reading momentary switches, either on mains power or on battery. As soon as I want to add a sensor that needs to send it's info on a set interval I needed it to be on mains power.
But like I said, I will convert the sketch to 2.1 this week, and next week I'll give the workaround a shot.
Keep you posted!

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

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 thebutton.hlibrary 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 REGthis 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 madeset it to 0 or increase to e.g. 10000...

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.

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.pdfChapter 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.

-
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.
-
@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!
-
Hi @Yveaux,
I have stripped it to one button on a RC-net and one led to see what I am doing, without changing the basic flow of the sketch. Also the node has been stripped bare. I have used a DIP version with the same bootloader (8MHz internal, 1V8 BOD by GertSanders, 3V3 power source) and the outcome is exactly the same:
- directly waking with 2.1.1, sleeping with 2.0.0.
- In both tests, all button presses are registered without problems.
- button library has nothing to do with it. When I use a simple
digitalRead(), all remains the same. - when I comment out the library call for the Interrupt (line 48), nothing changes.

- In MY_CORE_ONLY there's no
serial.begin(), makes one wait awfully long for debug output... - When the node is in PWR_DOWN, my (Chinesium) USB-serial converter is unable to wake the node to upload new code. I have to keep the node awake with the button, and if that fails, shoot the bootloader again. I know the DTS-pin is functional, as the node resets when I start a serial window.
-
@DavidZH The issue is caused because the way you use the sleep() function.
You 'abuse' the sleep() implementation that takes 2 interrupts (this prototype) to be able to sleep 'forever' (timeout 0).
However, by passing two invalid interrupt numbers, the MySensors stack translates this into a regular sleep() (this prototype) for which a timeout value of 0 means to return immediately.In the core, calling either sleep(0xff, 0x00, 0xff, 0x00, 0) or sleep(0) will lead to the same call to the hwSleep() implementation, which will return immediately.
As a quick test, could you try replacing the code starting here:
if (interrupt1 != INTERRUPT_NOT_DEFINED && interrupt2 != INTERRUPT_NOT_DEFINED) { // both IRQs result = hwSleep(interrupt1, mode1, interrupt2, mode2, sleepingTimeMS); } else if (interrupt1 != INTERRUPT_NOT_DEFINED && interrupt2 == INTERRUPT_NOT_DEFINED) { // one IRQ result = hwSleep(interrupt1, mode1, sleepingTimeMS); } else if (interrupt1 == INTERRUPT_NOT_DEFINED && interrupt2 == INTERRUPT_NOT_DEFINED) { // no IRQ result = hwSleep(sleepingTimeMS); }by
result = hwSleep(interrupt1, mode1, interrupt2, mode2, sleepingTimeMS);and see if that solves your issue?
-
It did! Thanks a bunch! I had a feeling it was to be found in that part of the code.
Strange thing is: it still returns -1 as wake up reason. And that brings me back to my original problem.
- When I want to add a timed sensor by setting a time as last argument, the node will not wake up when an interrupt takes place. It does register the interrupt, as the counter increases with every press. But it will only wake when the timer expires and only then display the updated counter.
I do see use cases for this: like an alarm-base station. With multiple inputs for the various detector loops. When the power fails (either by accident or intentionally) the base should go in low power mode to save the battery. And send a periodical heartbeat.
Or a scene controller in an inaccessible spot with a sensor attached.edit: I've been browsing around MyHwAVR.cpp for a while, but my coding is not at that high of a level at this moment, that I can provide any useful input.

Great!

Well, that function is setup to either return the interrupt number, or -1 if it didn't wake from interrupt.
You woke it differently, hence the return code of -1, see here.- When I want to add a timed sensor by setting a time as last argument, the node will not wake up when an interrupt takes place. It does register the interrupt, as the counter increases with every press. But it will only wake when the timer expires and only then display the updated counter.
The actual sleep method differs whether a timeout is passed or not, see here.
I would have to consult the datasheet and dive into the different sleeping methods, but that probably is the reason of not waking up.Again, you are using the library in an undocumented/untested way, so, unless you're able to read/modify the code yourself, I advise you to stick to the suggested use cases.
