Ciao a tutto,
sto iniziando a capire come funzionano i sensori di temperatura, ho un Dallas DS18S20. Ho scaricata la libreria OneWire e utilizzato il suo esempio per vedere se il tutto funzionava. Sino a qua tutto ok.
I problemi sono con la libreria DallasTemperature, scaricata dal sito (MilesBurton.com), ho scelto l'ultima versione la 3.0.6 del 2010. Premetto che utilizzo Mac per la programmazione di Arduino.
Nel caricare lo skect su Arduino Uno mi da un sacco d'errori e verificando vedo che la libreria non colorata d'arancione. Mi date un idea di cosa genera tutto questo ? Sembra che non trovi la libreria, ovviamente l'ho installata più volte.

You will need a 4.7K Ohm Resistor to "pull-up" the 1-Wire data line. You may use any combination of resistors 5x1k etc.
If you are using the DS18B20, ground pins 1 and 3. The centre pin is the data line '1-wire'.Devices supported:
DS18B20
DS18S20 - Please note there appears to be an issue with this series.
DS1820You may extend this functionality through strategies. Please post on Arduino.cc and contribute to the project
