To be safe its best to always specify them. </p> http://forums.leaflabs.com/topic.php?id=960#post-5904 Fri, 05 Aug 2011 15:17:40 +0000 house91320 5904@http://forums.leaflabs.com/ <p>I just wrote some code to use an i2c temp sensor that doesn't work<br /> #include &lt;Wire.h&gt;</p> <p>int temp_address = 74;</p> <p>void setup()<br /> {<br /> SerialUSB.begin();<br /> Wire.begin();<br /> }<br /> void loop()<br /> {<br /> Wire.beginTransmission(temp_address);<br /> Wire.send(0);<br /> Wire.endTransmission();<br /> Wire.requestFrom(temp_address, 1);<br /> while(Wire.available() == 0);<br /> int c = Wire.receive();<br /> SerialUSB.println(c);<br /> }<br /> and i tested it with the arduino and it works.
