I refreshed all the libraries. I'm able to compile and upload my sketches, but now it complains a lot about "invalid libraries."

At the moment, I cannot reproduce this with Linux and Arduino 1.8.2. I try to find out what's wrong.

Can you try to remove the .ci and .mystools folders?

BTW, I'm using the Windows version of Arduino IDE 1.8.5, which is the most current.

I don't know the correct path on an Windows system. On my system the Sketches are in the ~/Arduino folder in my home directory (~). The arduino-nrf5 is in ~/.arduino15/packages/sandeepmistry/hardware/nRF5/0.4.0 and the ArduinoHwNRF5 files are in ~/.arduino15/packages/MySensors/hardware/nRF5/0.2.1

mfalkvidd

on my Windows machine, all boards are located in c:\Users<username>\AppData\Local\Arduino15\packages
Strange that they've been installed to C:\Users\David\Documents\Arduino\libraries\ on your machine.

Maybe just delete the folders and re-install using the board manager?

NeverDie

@mfalkvidd All I know is that if I put a library in the folder: C:\Users\David\Documents\Arduino\libraries
it always gets detected and used. It also means you can completely uninstall/re-install the arduino IDE, and nothing gets lost. I'm not sure about other locations.

Am I the only one doing it this way?

mfalkvidd

@NeverDie for libraries, doing what you do should result in the same behavior as when using the Library Manager.
But I'm not sure it works with boards (especially given that the Arduino IDE complains when you put boards in the libraries folder).

NeverDie

I use the board manager to manage the boards. I believe it connects directly into github.

Anyhow, I stripped out all the non-library stuff, and now Windows IDE works without complaining.

NeverDie

Has anyone here yet figured out how to have more than one type of interrupt at a time wake-up the MCU from sleep? Based on the examples so far, it seems as though only one type at a time can be active. I'm sure there must be some way to do it. For instance, it would be desirable if the MCU could wake up not just from a timer event every, say, 5 minutes, to take a temperature reading, but also immediately if there is a leak detected. Right now it's just one or the other.

rmtucker

@NeverDie

So we can not use the normal statement

int8_t sleep(int interrupt, int mode, unsigned long ms=0);

I did not realize that was the case as i have never tried it.

NeverDie

I believe hwSleep(..) is the preferred incantation, but beyond that I'm not sure of anything. Maybe @d00616 can comment?

I should be receiving a number of different PCB projects tomorrow for final assembly and test, and if I can't resolve this soon, I'm simply going to release them without full demo code.

In MySensors, the regular way to use sleep mode is by using the sleep() functions:
https://www.mysensors.org/download/sensor_api_20#sleeping

But like you said, you can also use the raw hwSleep() from the hw abstraction layer. Or you could also rewrite it!
Which means at each abstraction layer, there are additional logics. sleep() functions have more logics (regarding MySensors states and features) than the raw hwSleep for example (like testing if there is an ongoing ota, smartsleep, heartbeat etc..). I have nodes where i use raw or not, but it's good to know what's behind.

@scalz
So the statement
int8_t sleep(int interrupt, int mode, unsigned long ms=0);
Can be used for timer and pin interrupt at he same time on the NRF5 platform just like the arduino?

NeverDie

I'll try it, but I have strong doubts that it's going to work.

FWIW, here's the pin mapping currently being supplied by digitalPinToInterrupt(..) for the nRF5:
Digital pin 0 = interrupt pin 0
Digital pin 1 = interrupt pin 1
Digital pin 2 = interrupt pin 2
Digital pin 3 = interrupt pin 3
Digital pin 4 = interrupt pin 4
Digital pin 5 = interrupt pin 5
Digital pin 6 = interrupt pin 6
Digital pin 7 = interrupt pin 7
Digital pin 8 = interrupt pin 8
Digital pin 9 = interrupt pin 9
Digital pin 10 = interrupt pin 10
Digital pin 11 = interrupt pin 11
Digital pin 12 = interrupt pin 12
Digital pin 13 = interrupt pin 13
Digital pin 14 = interrupt pin 14
Digital pin 15 = interrupt pin 15
Digital pin 16 = interrupt pin 16
Digital pin 17 = interrupt pin 17
Digital pin 18 = interrupt pin 18
Digital pin 19 = interrupt pin 19
Digital pin 20 = interrupt pin 20
Digital pin 21 = interrupt pin 21
Digital pin 22 = interrupt pin 22
Digital pin 23 = interrupt pin 23
Digital pin 24 = interrupt pin 24
Digital pin 25 = interrupt pin 25
Digital pin 26 = interrupt pin 26
Digital pin 27 = interrupt pin 27
Digital pin 28 = interrupt pin 28
Digital pin 29 = interrupt pin 29
Digital pin 30 = interrupt pin 30

NeverDie

The last I heard, from @d00616 , we had to supply code such as:

    // Enable interrupt
  NVIC_SetPriority(RTC0_IRQn, 15);
  NVIC_ClearPendingIRQ(RTC0_IRQn);
  NVIC_EnableIRQ(RTC0_IRQn);

and

// This must be in one line
extern "C" { void RTC0_IRQHandler(void) {rtcInterruptCounter++; NRF5_RESET_EVENT(NRF_RTC0->EVENTS_OVRFLW); NRF_RTC0->EVENTS_OVRFLW=0; }}

to get interrupts to work. Even with that approach, though, I haven't gotten it to support any interrupts in addition to a timed sleeping, though I have gotten it to support one interrupt that's separate from a timed sleeping (basically, sleeps indefinitely until the interrupt happens).

NeverDie

OK, I just now tried:

  sleep(3,CHANGE,3000);

and, as I suspected, it does nothing but sleep for 3 seconds. It's not responsive to any changes on pin P03 on an nRF52.

@scalz Are you getting a different result? It seems like there's a strong disconnect somewhere between what you're recommending and what I am experiencing.

I didn't give any recommandation, you misread. I just said the regular way to use sleep feature in mysensors, for users, is with sleep(..). But I agree, I misread you too! when you were asking for the specific nrf52 case I guess :)

That said, I got this working when I made my recessed node for door (accelerometer and hall effect sensor with sleeping). Maybe things have changed in the lib?? or not. I'm struggling between different version of the lib, and some are different from the dev branch.. I'll recheck this asap (not sure for this evening).

NeverDie

I tried toying around with it a bit, and I got a useful result:

#define MY_CORE_ONLY

#include <nrf.h>
#include <MySensors.h>


const byte ledPin = LED_BUILTIN;
const byte interruptPin = 3;
volatile byte state = LOW;

void blinkityBlink(uint8_t pulses, uint8_t repetitions) {
  for (int x=0;x<repetitions;x++) {
    for (int i=0;i<pulses;i++) {
      digitalWrite(LED_BUILTIN,HIGH);
      wait(20);
      digitalWrite(LED_BUILTIN,LOW);
      wait(100);
    }    
      wait(500);
  }
}

void setup() {
  hwPinMode(LED_BUILTIN,OUTPUT_D0H1);
  hwPinMode(interruptPin, INPUT);
  attachInterrupt(digitalPinToInterrupt(interruptPin), blink, RISING);
  blinkityBlink(2,1);  //signify power-on and start of main loop
}

volatile bool buttonPressed=false;
void loop() {
  state = !state;
  digitalWrite(ledPin, state);
  sleep(digitalPinToInterrupt(interruptPin), RISING, 3000);
  wait(20);  //wait 20 milliseconds for button to debounce if it was pressed
  if (digitalRead(interruptPin)) { //if button is pressed
    blinkityBlink(2,1);
  }
  if (buttonPressed) {
    buttonPressed=false;
    blinkityBlink(20,1);
  }
}

void blink() {
  buttonPressed=true;
}

So, with this approach, pushing the button on pin 3 does wake up the nRF52 from sleep, whereupon the button press can still be detected and serviced, but it also demonstrates that the ISR per se isn't working.

Anyhow, with this I'm able to get the PIR or leak sensor or magnet sensor or light sensor doing useful things in a timely manner, even if it isn't ideal. That puts me further ahead than I was before. :)

This is a test program that wakes up from either that i was using some time ago.

/**
   The MySensors Arduino library handles the wireless radio link and protocol
   between your home built sensors/actuators and HA controller of choice.
   The sensors forms a self healing radio network with optional repeaters. Each
   repeater and gateway builds a routing tables in EEPROM which keeps track of the
   network topology allowing messages to be routed to nodes.

   REVISION HISTORY
   Version 1.0 - Henrik EKblad

   DESCRIPTION
   This sketch provides an example how to implement a distance sensor using HC-SR04
   Use this sensor to measure KWH and Watt of your house meeter
   You need to set the correct pulsefactor of your meeter (blinks per KWH).
   The sensor starts by fetching current KWH value from gateway.
   Reports both KWH and Watt back to gateway.

   Unfortunately millis() won't increment when the Arduino is in
   sleepmode. So we cannot make this sensor sleep if we also want
   to calculate/report watt-number.
