<p>Thanks Edwin,<br/>
but the project is for raspberry alone, I have the UNIPI board 1.1 and the sensor is connected directly to the expansion card.<br/>
The sensor is connected to the RJ45 BUS 1Wire of unipi then I think the problem lies.</p>

I have problems in reading the DS18B20 connected to unipi 1.1 !!<br/>
I tried to load the OneWire draft CoDeSys but is not designed to unipi but for raspberry and it does not work.<br/>
How can I just read a value from the sensor?</p>
<p>I tried to enter the raspberry and typing:</p>
<p>PI3_MMM pi @: ~ $ cd / sys / bus / w1 / devices<br/>
pi @ PI3_MMM: / sys / bus / w1 / devices $ cd 28-0004442100ff<br/>
pi @ PI3_MMM: / sys / bus / w1 / devices / 28-0004442100ff $ cat w1_slave</p>
<p>00 00 00 00 00 00 00 00 00: crc = 00 YES<br/>
00 00 00 00 00 00 00 00 00 t = 0</p>
<p>It seems to not work !!<br/>
I have three sensors, and I tried them all with the same result.</p>
<p>Tips?</p>
<p>Thank you, Alberto</p></div>
