Baudrate of DS18B20


Baudrate of DS18B20

Postby yamadanao614 » Mon Jul 24, 2017 9:27 am

I'm trying to connect a DS18B20to my Beaglebone Black. Now I wan't to determine the Baudrate but can't find it in the Datasheet of the DS18B20.

In the internet I saw different ones (9600, 19200). Can I simply choose one the Sensor pick's up on it? If so up to what maximal rate?

Sorry for this RTFM question, but I really can't find the answer for that.

There are two operating modi for the 1-wire protocol: normal and overdrive. Normal operation can perform data transfers at up to 16.3 KBit/sec, and overdrive operation can transfer data at up to 142 KBit/sec. For details you can check the Wikipedia article on 1-wire or any of the many Beaglebone Black specific 1-wire articles on the web.
