  Sziasztok!

  Volna egy olyan problémám, hogy ez a kód:
  #include <OneWire.h>
  #include <SPI.h>
  #include <Ethernet.h>
  
  // Enter a MAC address and IP address for your controller below.
  // The IP address will be dependent on your local network:
  byte mac[] = {0xAD, 0xBD, 0xCD, 0xED, 0xFD, 0x0D};
  IPAddress ip(192, 168, 0, 100);
  
  // ThingSpeak Settings
  char thingSpeakAddress[] = "api.thingspeak.com";
  String writeAPIKey = "xxxxxxxxxxxxxxxxxxx";
  const int updateThingSpeakInterval = 16 * 1000; // Time interval in milliseconds to update ThingSpeak (number of seconds * 1000 = interval)
  
  // Variable Setup
  long lastConnectionTime = 0;
  boolean lastConnected = false;
  int failedCounter = 0;
  
  // Initialize Arduino Ethernet Client
  EthernetClient client;
  
  // Initialize the Ethernet server library
  // with the IP address and port you want to use
  // (port 80 is default for HTTP):
  EthernetServer server(80);
  
  
  OneWire ds(10); // on pin 10 (a 4.7K resistor is necessary)
  
  void setup() {
  // Open serial communications and wait for port to open:
  Serial.begin(9600);
  while (!Serial) {
  // wait for serial port to connect. Needed for Leonardo only
  // Start Ethernet on Arduino
  startEthernet();
  }
  
  
  // start the Ethernet connection and the server:
  Ethernet.begin(mac, ip);
  server.begin();
  Serial.print("server is at ");
  Serial.println(Ethernet.localIP());
  }

  byte i;

  Serial.print(OneWire::crc8(data, 8), HEX);
  Serial.println();
  
  // Convert the data to actual temperature
  // because the result is a 16 bit signed integer, it should
  // be stored to an "int16_t" type, which is always 16 bits
  // even when compiled on a 32 bit processor.

  No more adresses dob serialon és nem is megy tovább a program, legalábbis Thingspeaken nem látnám hogy akarmi menne (api kód kitöltve), ha csak egy sima példa programot futtatok akkor ott küld adatot.
  Ha csak onewire példát futtatok akkor működik.
  Egybe a kettőt nem tudom.
  Uno van w5100 shielddel

  szerk.:
  A shieldet elég egyébként csak spi-n összekötni? pl ha nanoval akarom majd összehozni?
