https://devzone.nordicsemi.com/f/nordic-q-a/545/1-wire-code-problemHello, Having a problem with the 1 wire sensor DS1820, I&#39;ve created my own 1 wire protocol functions. They compiled without any errors. but when I run my program, it only shows the temperature value 4095 constantly. Kindly take a look into my code anden-USTelligent Community 13Mon, 30 Sep 2013 15:21:59 GMThttps://devzone.nordicsemi.com/thread/2800?ContentTypeID=1Mon, 30 Sep 2013 15:21:59 GMT137ad170-7792-4731-bb38-c0d22fbe4515:53738532-9e5c-479c-81eb-932330de0ef1umair<p>thank you for letting me know sir :), can you also tell me where can I get 1 wire protocol timing diagram for accessing any device.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/2799?ContentTypeID=1Mon, 30 Sep 2013 13:32:58 GMT137ad170-7792-4731-bb38-c0d22fbe4515:78b6f74a-c01f-4b8f-bcbe-fe6003142509Ole Morten<p>I don&#39;t have any experience with this sensor or protocol, but have you actually verified that your high and low periods are correct? It seems a little odd that your comments says &quot;// leave it low for 480us&quot;, and the code snippet is nrf_delay_us(29), which will normally pause for ~29 µs, not 380.</p> <p>I&#39;d therefore recommend you to get hold of a logic analyzer and see what actually happens on your lines, to make sure that this is correct, and as you expect.</p><div style="clear:both;"></div>
