Re: [Tinyos-help] External interrupt mica2

Hi,

it is still not working.

But I have placed the code in start and have changed this two lines, cause i am using pin6 (INT0)

sbi(EICRA,ISC01);
sbi(EICRA,ISC00);

Now I do not get the interrupt. But unfortunately i do not get it with hardware,too. And there is an interrupt raised.

Does anyone how much volt the signal should have? I use 3V and I use half a second as duration, which is too long. But I get not a single interupt...

Hi,

I want to create an interrupt with an own circuit for mica2.

In my program I do this in init():

// -- Triger on rising edge
  sbi(EICRB,ISC01);
  sbi(EICRB,ISC00);
  //-- Enable Interrupt
  sbi(EIMSK , INT0);

and I have added this:

//Interrupt routine
TOSH_SIGNAL(SIG_INTERRUPT0){
  call Leds.yellowOn();
  if (busy != 0){
   call CountTime.Start();
   atomic
    {
     busy = 1;
    }
   call Timer.start(TIMER_ONE_SHOT, delaytime * 8);
   }
    }

However, when I switch on the mote i get directly this interrupt. But somehow it does not start the timer... I have added an LED to check in timer.fired.

I have not even attached the hardware.

Best Regards,

Patrick Kuckertz
