Read the sensors after about 5 minutes (there is not way to say, how many seconds of sleep we skipped due to the PIR interrupt - or u check the WDIF after sleep.). Sei() // pending interrupts will b processed after next instruction, so we dont sleep foreverĪsm("sleep\n") // wakeup after 8SEC or after PIR interrupt Configuration variables:¶ runduration (Optional, Time): The time duration the node should be active, i.e. Example configuration entry deepsleep: runduration: 10s sleepduration: 10min. PIR interrupt is already enabled in setup() While in deep sleep mode, the node will not do any work and not respond to any network traffic, even Over The Air updates. I have to actually lift the lid somewhat to wake it up. After its been asleep for some time (or I do a hard sleep from Start), I cant wake it with the keyboard or mouse. I normally use my laptop as a desktop with the lid down. What about this structure (in PSEUDOCODE): void setup() The solution seemed to work for a day or two, then it went back to having the same problem. Ur timing would b more accurate then even if the PIR is upset… I mean: no other interrupts but the watchdog interrupt? Would it b ok, if it just sleeps 16msec and then looks, if the PIR acts up? Isnt the power consumption the only reason for all this? So, what do you think I should do? (the power consumption I have noticed is not the main issue, so let's focus on the interrupt and sleep for 5mn issue first). I cannot get why the behavior I have happens all the time. "Īnd that means the library should be modified to take into account this kind of situation, or that I should write directly the piece of code without relaying on this library, no?Įven if I could fall in this situation sometimes. The sleep enable bit can be cleared during the ISR and thus the MCU will not go to sleep. The ISR will run, the interrupt will be detached, and then the CPU will enter sleep mode with no interrupt enabled. "The problem is if the interrupt occurs after attachInterrupt but before sleep_cpu(). Warning Code like this, which is a typical example of sleep code, can cause a problem if you are relying on the interrupt to wake you from sleep: (this is typically what is done when yopu are using the LowPower library since I call the attachInterrupt function, the call LowPower.powerDown(.) function): attachInterrupt(0, pin2_isr, LOW) I think the library is using: SLEEP_MODE_PWR_DOWNįrom what I have read, is it possible that I am in the following situation: I want to sleep more than 8s since I need to read the sensors once every 5mn (but during this sleep time, the PIR should be able to interrupt the sleep and put the arduino back to sleep) Lightweight Low Power Arduino Library – Rocket Scream The LowPower arduino library is the following: Thanks for the answers, here are the requested details:
