Gehe zu: C - Programmierung (GCC u.a.) Nach oben When the timer runs up, the sleeping variable is set to false and the sleep loop is left until you again release the button! ATmega328P is the microcontroller on the Arduino UNO Board. When you release the button too early, the timer is stopped and deep sleep is re-entered Watchdog Timer, Pin Change Interrupt and Wake-up Power-on Reset, Internal and External Interrupts Operating Voltage:1.8V to 5.5V for 0 4MHz, 2.7V to 5.5V for 0 10MHz and 4.5V to 5.5V for 0 20MHz speed grades. Whenever an ISR is returning, it re-enters the normal execution, the call after your sleep(), so when the button is pressed but sleep remains true(because your time dod not run out yet), you automatically returns to lo power mode, waiting for either the timer to execute an interrupt or the button to be released If (current = LOW & previous = HIGH) when the button is not pressed, the cpui enters deep sleep until you press the button

if the button state changes to pressed, remember the start time Unsigned long firstTime // how long since the button was first pressedĭigitalWrite(inPin, HIGH) // Turn on 20k pullup resistors to simplify switch input The only wake-up sources are the pin change interrupt and TWI address match.

Long secs_held // How long the button was held (seconds) Long millis_held // How long the button was held (milliseconds) (LOW is pressed b/c i'm using the pullup resistors) Int current // Current state of the button It means the interrupt wake up not in the loop if(!check) but somehow it restart the program again.Code: int inPin = 2 // the pin number for input (for me a push button) I see the LED PIN 19 is blink but after that LED PIN 15 blink after that. However, whenever I try to use PIN 11 to wake up from deep sleep mode when sleepNow() executed. So I have a interrupt wake up inside a if(!check) loop.

Thank you very much I have really long code so that's why I could not post full code here. In this way into your code you can understand that an interrupt has happened. But I can only tell you can use a variable and change it into wakeUp() function. and also it's not a real code and it is a prototype. I can't understand your code because the braces is not correct to find out which code runs under what condition. Sleep_cpu () // here the device is put to sleep Interrupts () // interrupts allowed now, next instruction WILL be executed Sleep_enable () // enables the sleep bit in the mcucr registerĪttachInterrupt (digitalPinToInterrupt (11), wake, LOW) // wake up on low level on D11 NoInterrupts () // make sure we don't get interrupted before we sleep Sleep_disable () // first thing after waking from sleep:ĭetachInterrupt (digitalPinToInterrupt (11)) // stop LOW interrupt on D11 interrupt service routine in sleep mode It means the interrupt wake up not in the loop if(!check) but somehow it restart the program again. When we put a microcontroller into deep sleep, we can use the watchdog timer as an interrupt, causing the. So I have a interrupt wake up inside a if(!check) loop. A watchdog can wake the processor from deep sleep.

Using external interrupt Pin (Not working).

Using Watch Dog Timer to wake up every 2 minutes.

Sorry for my bad explain but it is a little bit confused. I have a question regrading to deep sleep mode and interrupt pin.
