Arduino hoz kérhetek egy kis segítséget?

Mindegyik közt 3 másodperc szünettel semmi változás.

#include <OneWire.h>

#include <DallasTemperature.h>

OneWire oneWire(10);

DallasTemperature sensors(&oneWire);

void setup()

{

Serial.begin(9600);

sensors.begin();

}

void loop()

{

{

sensors.requestTemperatures();

float currentTemp0;

currentTemp0 = sensors.getTempCByIndex(0);

Serial.print(currentTemp0);

delay (3000);

float currentTemp1;

currentTemp1 = sensors.getTempCByIndex(1);

Serial.print(currentTemp1);

delay (3000);

float currentTemp2;

currentTemp2 = sensors.getTempCByIndex(2);

Serial.println(currentTemp2);

delay (3000);

}

delay (10000);

}

Arduino UNO R3

Van két változat is mind a kettő ugyan ezt csinálja. Az a furcsa hogy kettövel müködik de hárommal nem.

#include <OneWire.h>

#include <DallasTemperature.h>

/*-----( Declare Constants )-----*/

#define ONE_WIRE_BUS 2 /*-(Connect to Pin 2 )-*/

/*-----( Declare objects )-----*/

/* Set up a oneWire instance to communicate with any OneWire device*/

OneWire ourWire(ONE_WIRE_BUS);

/* Tell Dallas Temperature Library to use oneWire Library */

DallasTemperature sensors(&ourWire);

/*-----( Declare Variables )-----*/

void setup() /*----( SETUP: RUNS ONCE )----*/

{

/*-(start serial port to see results )-*/

delay(1000);

Serial.begin(9600);

Serial.println("YourDuino.com: Temperature Sensor Test Program");

Serial.println("Temperature Sensor: DS18B20");

delay(1000);

/*-( Start up the DallasTemperature library )-*/

sensors.begin();

}/*--(end setup )---*/

void loop() /*----( LOOP: RUNS CONSTANTLY )----*/

{

Serial.println();

Serial.print("Requesting temperature...");

sensors.requestTemperatures(); // Send the command to get temperatures

Serial.println("DONE");

Serial.print("Device 1 (index 0) = ");

Serial.print(sensors.getTempCByIndex(0));

Serial.println(" Degrees C");

Serial.print("Device 1 (index 0) = ");

Serial.print(sensors.getTempFByIndex(0));

Serial.println(" Degrees F");

Serial.print("Device 1 (index 0) = ");

Serial.print(sensors.getTempFByIndex(0));

Serial.println(" Degrees G");

delay(5000);

}

Ezzel is ugyan az kettövel müködik hárommal nem csak itt 0 32 32 hömérsékletet ad vissza.

Serial.begin(9600);

Serial.print("Initializing Temperature Control Library Version ");

Serial.println(DALLASTEMPLIBVERSION);

// Initialize the Temperature measurement library

// set the resolution to 10 bit (Can be 9 to 12 bits .. lower is faster)

sensors.setResolution(Probe03, 10);

}//--(end setup )---

void loop() /****** LOOP: RUNS CONSTANTLY ******/

{

Serial.println();

Serial.print("Number of Devices found on bus = ");

Serial.println(sensors.getDeviceCount());

Serial.print("Getting temperatures... ");

Serial.println();

// Command all devices on bus to read temperature

sensors.requestTemperatures();

Serial.print("Probe 01 temperature is: ");

printTemperature(Probe01);

Serial.println();

Serial.print("Probe 02 temperature is: ");

printTemperature(Probe02);

Serial.println();

Serial.print("Probe 03 temperature is: ");

printTemperature(Probe03);

Serial.println();

}//--(end main loop )---

/*-----( Declare User-written Functions )-----*/

void printTemperature(DeviceAddress deviceAddress)

{

float tempC = sensors.getTempC(deviceAddress);

if (tempC == -127.00)

{

Serial.print("Error getting temperature ");

}

else

{

Serial.print("C: ");

Serial.print(tempC);

Serial.print(" F: ");

Serial.print(DallasTemperature::toFahrenheit(tempC));

}

}

három érzékelővel ez is mind nulla. Kettővel pedig "Error getting temperature"

Jól értelmezem hogy it egyenként meg kell határozni az érzékelők cimeit "DeviceAddress"? pl ezzel a programmal [link]
