attachInterrupt() Not Working arduino nano Please help

Why is splitted in two devices ? because for one nano its too high load .

23

I think it is intended as a one-shot file write and you need to re-cycle the power to do a new write cycle.

Exactly ! :slight_smile: the too much printing is for debugging (Serial Plotter)

25

ok, and that magically unnamed pins doing communication between two boards, am i right?

26

what you mean?

27 
  if (encoderPosition <= 0 && continue123 == 1  ) {
    encoderPosition = 0;
    Serial.println("ENCODER_POSTION0");
    digitalWrite(5 , LOW); // << -- no name

  pinMode(3 , INPUT); // << -- no name
  pinMode(7, INPUT_PULLUP);// << -- no name
28

I'd move this whole chunk of the updateEncoder ISR into loop:

  Serial.println(encoderPosition);
  //Serial.println(encoderPosition);
  if (encoderPosition >= 9000 && continue123 == 0 && przycisk == 1 ) {
    encoderPosition = 9000;
    Serial.println("ENCODER_POSTION9000");
    continue123 = 1;
    digitalWrite(5, HIGH);
  }
  if (encoderPosition <= 0 && continue123 == 1  ) {
    encoderPosition = 0;
    Serial.println("ENCODER_POSTION0");
    digitalWrite(5, LOW);
    przycisk = 0;
    continue123 = 0;
    SD_WRITE = 1;
  }

... and carefully read the encoder, guard it with a state change detection on encoderPosition like this completely untested snippet:

  noInterrupts();
  int myEncoderPosition = encoderPosition;
  interrupts();
  static int myLastPos = -1; // remember a last reading for state change detection
  if (myEncoderPosition != myLastPos) {
    myLastPos = myEncoderPosition;
    Serial.println(myEncoderPosition);
    //Serial.println(myEncoderPosition);
    if (myEncoderPosition >= 9000 && continue123 == 0 && przycisk == 1 ) {
      myEncoderPosition = 9000;
      Serial.println("ENCODER_POSTION9000");
      continue123 = 1;
      digitalWrite(5, HIGH);
    }
    if (myEncoderPosition <= 0 && continue123 == 1  ) {
      myEncoderPosition = 0;
      Serial.println("ENCODER_POSTION0");
      digitalWrite(5, LOW);
      przycisk = 0;
      continue123 = 0;
      SD_WRITE = 1;
    }
  }

Also use the loop's myEncoderPosition copy of in the array writing because interrupts could corrupt use of encoderPosition.

Does it take 10s to do the first +10000 steps?

I think it could be this:

interacting with:

and writing past myList2[69] after 70000ms.

Maybe try

	if (przycisk == 1 &&  (millis() - przerwa )>= 1000){
		myList[cdk] = (analogRead(A1)/20.46);
		myList2[cdk] = (encoderPosition);
		przerwa = millis();
        if (cdk<70) cdk++; // protect against overwriting end of array.
	}

Or:

	if (przycisk == 1 &&  (millis() - przerwa )>= 1000){
		myList[cdk] = (analogRead(A1)/20.46);
		myList2[cdk] = (encoderPosition);
		przerwa = millis();
        cdk++; 
        if (cdk>=69) cdk = 35; // protect against overwriting end of array. 
	}

And instead of '70' in multiple places, you should add a const int ArraySize=70; and use that.

Or open the file and write the data directly to the SD card during the processing and completely skip storing it in a temporary array.

thx you bro i work well
