PIR as Interrupt problem

hello everyone,

i'm having issue pir interrupt on pin 2

i need send integer number when pir trigger activated, making arduino wake sleep , send 433mhz module, , go sleep.

to see if arduino sleeping i'm measuring milli amperes required power it, it's arduino on breadboard!

i have ir receiver on pin 3, works perfectly, pir goes this:

• go sleep setup (goes down 1,1 ma)
• wake when interrupt triggered (current change 13,2 ma)
• send code
• go sleep (again goes down 1,1 ma)
• wake again no reason not executing code (it stays on 13,2 ma , not execute code)
• stays there until trigger activated

i don't know i'm doing wrong

attached post you'll find code

thank in advice who's gonna me!
peace!

i read trough , there few things...

first, stop using delays! in interrupts, it's sin use them there. interrupts need short possible flow of rest of program can happen. , delay serial before going sleep, use while(serial.flush()). okay delays ones boot debug messages.

as if wake sleep first need call sleep_disable(). also, why call ir() after sleep if it's connected interrupt?

in ir() disable interrupts. how suppose turn on again?

skip "decode_results signals;" global, put inside ir(). , stay away string class. just:

code: [select]


void ir() {
  decode_results received;
 
  {
    irrecv.decode(&received);
    string received = string(signals.value, hex);
    serial.println(received);

    if (received.value == 0xffa25d){
      allarm = !allarm; //i call variable alarmenable make clear it's not alarm itself
      if (allarm){
        serial.println("allarme on");
        //nointerrupts();
        transmit_integer(funct[0]);
      }
      else{
        serial.println("allarme off");
        //nointerrupts();
        transmit_integer(funct[2]);
      }
    }
  }while((digitalread,3) == high);
}

or better, instead of transmitting stuff in interrupt, set flag alarm state changed , send in loop.

and smalls stuff make easier. use better variable names, strick 1 stye (bracket after if or on next line) , fix indentations!
