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
Phil
