AVR Freaks

I guess it is also important to use the appropriate pin assignments for timing opperations as for the PWM pins?

Hello!

Below is the code that I am successfully using to measuring time when threshold is either above .

It works on tiny45, however, due to the return it does that only once until called again...

Is there a way to return a value and continue? Actually, I am not really sure, if the return is the right way to use it here...

Any comments are more than welcome!

// ok time above HT
unsigned long timeAboveHT() {
  uint16_t myProx = Sensor.getProximity();
  //measure time change to a method that returns elapsed time!
  elapsedTime = 0;
  if (myProx > HT) {
    // fadeUp = !fadeUp;  //fade Rotation
    startTime = millis();
    //elapsedTime = 0;
    while (Sensor.getProximity() > HT) {
      currentTime = millis();
      elapsedTime = currentTime - startTime;
      //Serial.println(elapsedTime);
    }
  }
  return elapsedTime;
}

I am calling this method in the main loop:

 if (timeAboveHT() < 500) {
    ledState = !ledState;
  }

afterwards I make a decision with regard the led state:

if(ledState){
    analogWrite(ledPin, 255);
}

It works, however, I want to print out the ledState, it only returns at each step, which is ok, but how print the ledState endlessly? 

Best.

Thanks for this, looks impressive!

Is it possible that due to the use of other library the code takes less memory?

Best.

Hello all!

I have put some code together, have a look. Somehow I cannot get this library going properly ( https://github.com/SV-Zanshin/VC... ). Namely , I am having problems with setting the threshold... While I have been trying also this library ( https://adafruit.github.io/Adafr... ) it apparently works better, but the down size is there is no support for the interrupt on VCNL. So, I am wondering, can I use one library for reading prox, while other for interrupt? I know this is stupid and it will take more memory... however, it will work?

Anyway, below is the code for the basic test of proximity, with the setT() I want to make the setting of the high threshold (HT), which should be 3% over the getProximity() , but does it work? Are the variable declared properly, will the sensor provide me this number? I do not have a debugging on tiny, so I cannot see what is going on, anyway, when I run the code on my breadboard , the main led is lid, without even getting close to the sensor. 

PS the library is available at GitHub, however, I have port this library to tiny, which I am using in a local sketch... I am attaching the .cpp and .h

And yes, I am still going back to the initial question, why it works on Arduino and does not on tiny? BTW it compiles...

}

  if(Sensor.getProximity() > HT){
    analogWrite(ledPin, 255);
  }
  else if(Sensor.getProximity() < HT){
    analogWrite(ledPin, 0);
  }
}

// set the thresholds
void setT() {

  static uint16_t offSet;
  static uint16_t percentage;

  percentage = 103;

  offSet = Sensor.getProximity();

  HT = ( (offSet / 100) * percentage );  

}

  Sensor.setProximityFreq(0);

  //Set ambient
  //Sensor.setAmbientLight(2, 128);

  // Continuously sample proximity using frequency and averaging settings
  Sensor.setProximityContinuous(true);

  // Turn off continousl ALS reading due to power consumption
  Sensor.setAmbientContinuous(false);
}

Hello, no problems when using with At Tiny, but when on Arduino I am having problems with using/starting the library... anyway, I am using the Adafruit to do that... Thank you.
