Has anyone had any success implementing the Dallas one-wire protocol on the NRF51822 - in particular with the DS18B20 temperature sensor?</description><dc:language>en-US</dc:language><generator>Telligent Community 13</generator><lastBuildDate>Thu, 11 Jan 2018 16:58:13 GMT</lastBuildDate><atom:link rel="self" type="application/rss+xml" href="https://devzone.nordicsemi.com/f/nordic-q-a/29003/nrf51822-and-one-wire" /><item><title>RE: NRF51822 and one wire</title><link>https://devzone.nordicsemi.com/thread/114702?ContentTypeID=1</link><pubDate>Thu, 11 Jan 2018 16:58:13 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:f235e9fc-4dd7-4982-abfe-b5a4df8a7832</guid><dc:creator>Arepa</dc:creator><description>&lt;p&gt;Hi pabigot, is your implementation compatible with nRF52 modules?
