Interrupts don't work

Regardless of the mcu I select no interrupt or timer works. But the code works just fine on the physical circuit. Is this a bug or some setting I need to do of sort?

Hi.
Difficult to know what is the problem without more information.

You can open and test some examples to see if everything is ok:
File Explorer->Examples->Micro.

I wrote the follwing code that works except when I use the simulator

#include
#include
#include

ISR(INT0_vect){
PORTB = 0xff;
_delay_ms(10000);
}

int main(){

MCUCR |= (1 << ISC11 | 1 << ISC01);
GIMSK |= (1 << INT0 | 1 << INT1);
sei();
DDRD = 0x00;
PORTD = 0xff;
DDRB = 0xFF;
while (1)
{
/* code */
PORTB = 0xff;
_delay_ms(500);
PORTB = 0x00;
_delay_ms(500);
}
return 0;
}

To post code please use the"code" button.
If not, the includes will not appear.

And which Microcontroller are you using?

I'm using the attiny4313 , I tried the 2313 but it didn't work either.

here's the code again

Code:



#include <avr/io.h>
#include <util/delay.h>
#include <avr/interrupt.h>

ISR(INT0_vect){
  PORTB = 0xff;
  _delay_ms(10000);
}

int main(){

  MCUCR |= (1 << ISC11 | 1 << ISC01);
   GIMSK |= (1 << INT0 | 1 << INT1);
  sei();
  DDRD = 0x00;
  PORTD = 0xff;
  DDRB = 0xFF;
  while (1)
  {
    /* code */
    PORTB = 0xff;
    _delay_ms(500);
    PORTB = 0x00;
    _delay_ms(500);
  }
  return 0;
}


Thanks.

There is an error in an xml file, you can fix it yourself:
data/AVR/tinyx313/tinyx313_regs.xml

At line 95, change mask="00010011" for mask=""
at line 112, change mask="00000111" for mask="11100000"

It more or less broke the 1.0.0 version and in the 1.1.0 it detects the interrupt but won't return from it

It is working for me.

Can you explain what that means?

and in the 1.1.0 it detects the interrupt but won't return from it

Did you wait 10 seconds (circuit time)?

In the stable version the mcu won't read the code, I used the mcu monitor and only portd is what it should be.

in version 1.1.0 it works when I push the push button but i waited like 5 minutes and it still keeps all the leds on. It's like it won't return from the interrupt , this is also a similar to a problem I have whenever I use assembly , it won't return from subroutines unless I use rcall , ret doesn't work.

Update on the test with version 1.0.0 , the problem is the sei() function , when I remove it the code works as should , minus the enable interrupts. But with it it's like none of the other registers actually have the value I try to load in them

Try this code:

Code:


#define F_CPU 8000000L

#include <avr/io.h>
#include <avr/interrupt.h>
#include <util/delay.h>

ISR( INT0_vect ){
    PORTB = 0xf0;
    _delay_ms(1000);
}

ISR( INT1_vect ){
    PORTB = 0x0f;
    _delay_ms(1000);
}

int main()
{
    MCUCR |= (1 << ISC11 | 1 << ISC01);
    GIMSK |= (1 << INT0 | 1 << INT1);
   
    DDRD = 0x00;
    PORTD = 0xff;
    DDRB = 0xFF;
   
    sei();
   
    while (1)
    {
        PORTB = 0x00;
    }
    return 0;
}

Seems that in 1.0.0 an unintented interrupt is triggered at sei().

1.1.0 is working ok for me.

I tried the code, it worked for the first press at the start of the simulation , but afterwards it doesn't work again

Ok, definetly 1.0.0 is triggering an extra interrupt, apart of that it is working ok
But let's leave this version aside for now.

1.1.0 is working for me in all cases (circuit and code attached).
Maybe you are using a different circuit.
If you want to share it I can test.

It worked, my code works when I build it using microchip studio, I've been using platform io to build it , why is this the case?

Nice to know.

How do I fix the timer issue , the timers don't start

I forgot to add the mcu, I'm using the tiny4313, the timer won't start

I have this code

Code:


TCCR1B = (1<<CS12|1<<CS10|1<<WGM12);
  OCR1A = 7812;
  TIMSK = (1<<OCIE1A);


and for the isr

Code:

ISR(TIMER1_COMPA_vect){
  seconds=20;
  if(seconds == 60){
    seconds = 0;
    minutes++;
  }
  if(minutes == 60){
    minutes = 0;
    hours++;
  }
  if(hours == 24){
    hours = 0;
    minutes = 0;
    seconds = 0;
  }
}

i also tried timer0

Thanks for the code, I will have a look.

Hello ,
Did you get a chance to take a look at the problem with the timers in the tinyx313 MCUs?

Hi.
Yes, confirmed that Timer1 is not working, I'm working on it.
Timer0 works for me, but maybe does not work in all configurations.
