<div class="markdown_content"><p>I have find solution to change resolution on internet:<br/> You have to use an other gpio than gpio4, like gpio25 in pin22 and only 1 ds18b20 plug in to do change:</p> <p>sudo git clone <a class="" href="https://github.com/danjperron/BitBangingDS18B20" rel="nofollow">https://github.com/danjperron/BitBangingDS18B20</a><br/> cd BitBangingDS18B20<br/> sudo gcc -lrt -o configDS18B20 configDS18B20.c</p> <p>sudo ./configDS18B20 25</p> <p>I have change resolution of 5 ds18b20 to 10 bits. Time now must be 187.5ms x 5= 938ms. But, the cycle time is still 4 seconds !<br/> Is it CODESYS ? Raspbian ? I don't understand ....<br/> Help ...</p></div>

<div class="markdown_content"><p>I have connect 5 DS18B20 on my Rpi3. The time to ask value of 5 sensor is more than 4 seconds !<br/> I see in documentation of DS18B20 the time for resolution 12bits is 750 ms. In 10bits resolution time is only 187ms.<br/> How can I change resolution of my sensors ? It's not in the library in codesys, I think it's in raspbian.<br/> Could you help me ?<br/> Bests regards.</p></div>
