OneWire error message

I’m new to Arduino and I’m trying to get the address for a onewire temp probe.

When I try to verify the one_wire_address_finder code in arduino 1.03 I get the following errors

one_wire_address_finder:9: error: ‘OneWire’ does not name a type
one_wire_address_finder.pde: In function ‘void discoverOneWireDevices()’:
one_wire_address_finder:23: error: ‘ds’ was not declared in this scope
one_wire_address_finder:35: error: ‘OneWire’ has not been declared
one_wire_address_finder:41: error: ‘ds’ was not declared in this scope

Code is below

// This sketch looks for 1-wire devices and
// prints their addresses (serial number) to
// the UART, in a format that is useful in Arduino sketches
// Tutorial:
// http://www.hacktronics.com/Tutorials/arduino-1-wire-address-finder.html

#include <OneWire.h>

OneWire ds(3); // Connect your 1-wire device to pin 3

void setup(void) {
Serial.begin(9600);
discoverOneWireDevices();
}

void discoverOneWireDevices(void) {
byte i;
byte present = 0;
byte data[12];
byte addr[8];

Serial.print(“Looking for 1-Wire devices…\n\r”);
while(ds.search(addr)) {
Serial.print("\n\rFound ‘1-Wire’ device with address:\n\r");
for( i = 0; i < 8; i++) {
Serial.print(“0x”);
if (addr < 16) {

  • Serial.print(‘0’);*
  • }*
    _ Serial.print(addr*, HEX);_
    _
    if (i < 7) {_
    _
    Serial.print(", “);_
    _
    }_
    _
    }_
    _
    if ( OneWire::crc8( addr, 7) != addr[7]) {_
    _
    Serial.print(“CRC is not valid!\n”);_
    _
    return;_
    _
    }_
    _
    }_
    _
    Serial.print(”\n\r\n\rThat’s it.\r\n");_
    ds.reset_search();
    _
    return;_
    _
    }_
    void loop(void) {
    _
    // nothing to see here*_
    }
    I know its probably something simple I’m missing.
    Any help you can give me would be greatly appreciated
    Thanks

Did you download and install the OneWire library? Where?

Thank you

I knew it was simple. I put the library in the right spot and it works now.
