    API pulse measure

    Hi,
    I'd like to use arduino to send to HS data about electricity power.
    I have a system that send a pulse (+5V) every watt.
    Using this sketch on serial monitor all is ok:

    Code:
    // Pin impulso
const int getpulsepin = 2;

// variabili
float assorbimento = 0.0;
unsigned long startime = 0;
unsigned long durata = 0;
int stato = 0;
int pinval = 0;

void setup() {
  Serial.begin(9600);  
  pinMode(getpulsepin, INPUT); // pin dell'anemometro
}


void loop ()  
{ 
    pinval = digitalRead(getpulsepin);   // read sensor pin
 
    if ((stato == 0) & (pinval == 1)) { // transition point
    durata = millis() - startime;       // duration pulse
    startime = millis();            // reset millis startime 
    assorbimento = 3600.0/durata*1000;  // Wh
    }
 
    stato = pinval;         // 
    Serial.print("assorbimento KW/h = ");
      Serial.println(assorbimento);  
}

    Created a API board in HS, selected device 1 as IMPUT and loaded the arduino API sketch:

    Code:
    //For serial set to 0 and for Ethernet set to 1
#define ISIP 0

//Do NOT modify these
#if ISIP == 1
#include <EEPROM.h>
#include <SPI.h>       
#include <Ethernet.h>
#include <EthernetUdp.h> 
#endif

    Were the translation of "Exception in RecievedText: Riferimento a un oggetto non impostato su un'istanza di oggetto." is "Exception in RecievedText: Object reference not set to an instance of an object."

    Where I'm wrong?

    This is my last step and then i can switch all my automation on arduino (I/O, PWM, etc. work well).

    Thanks

    I think this is an old bug in the API setup. Please back up your system then run the beta that is in the updater as it is fixed in there.

      Thanks Greig! Ok, now work well, or quite well...
      Is not important for me, but is it possible pass to HS a decimal value?
      I'm trying using float, but no decimal in HS devices.
      Example, I count the time between 2 pulse, are 12435 millisecond. I'd like to see 12,435sec on HS device.
      Do you think that the italian setting for decimal number could be the problem? (i use 12,435 (comma) and not 12.435 (dot).

      Thanks

        Can you not change the device decimal place in the device config status graphics setup?

          Greig.
          Could be that I didn't understood correctly your suggestion, but in the device config --> status graph --> add new range value if i insert "2" in "Dec Places" box, nothing change.

          Do you think that I have to pass two different data by API input?
          -a integer for device value
          -a float or string for device string

          A little other info:
          In "Arduino Plugin Config" tab, when i select board 2, appear a message "Building board n2 setup" and the screeen is quite gray color.
          The log:
          PHP Code:
          lug-12 18:49:07         Arduino Plugin    Updating Values on Board No: 2

          Is it normal?
