title: Arduino Nano: is SPI supported?
body: <p>Can SPI hardware on the Arduino Nano be used?</p>
  
  <p>On the <a href="http://arduino.cc/en/Main/ArduinoBoardNano" rel="noreferrer">Nano page</a> it says:</p>
  
  <blockquote>
    <p>SPI: 10 (SS), 11 (MOSI), 12 (MISO), 13 (SCK). These pins support SPI
    communication, which, although provided by the underlying hardware, is
    not currently included in the Arduino language.</p>
  </blockquote>
  
  <p>Yet there is an <a href="http://arduino.cc/en/Reference/SPI" rel="noreferrer">SPI library</a>.</p>
  
  <p>Please can someone explain this contradiction? I think, either</p>
  
  <ul>
  <li>The nano page is out of date</li>
  <li>SPI library is unsupported for the Nano SPI hardware but is supported on other boards</li>
  <li>SPI library is implemented for the Nano in software only</li>
  </ul>
  
  <p>Which is it?</p>
  
  <p>Thanks</p>
