DS1820 or DS18S20 or DS18B20 or DS1822…
I saw that for do it I must write on the byte 4 of the scratchpad I was trying with the write scratchpad 4Eh, it transmit 3 data bytes byte 2, 3 and 4 but all the tieme that I was trying nothing happened.
Hi, Try source code, I think it will work. First of all thank you for your help About sensor is right that are different, but with your example booth works perfectly the only thing is that the ds resolution is configurable to 9, 10, 11, or 12 bits.
Multi-drop capability simplifies distributed temperature sensing applications. Users browsing this forum: Wed Mar 05, 1: Mon Mar 03, Unique 1-wire interface requires only one port pin for communication. User—definable temperature alarm settings.
Why when I read the valor I move 8 position to the left and add again the temp valor? The display format of the temperature is ‘xxx.

Of course, you don’t need to use this method, you can use, for example, IntToStr routine from Conversion library: Wed Mar 05, Requires no external components. Fri Mar 07, 5: The DSPAR communicates over a 1-wire bus, which by definition requires only dx1822 data line and ground for communication with a central microprocessor.
As default resolution the ds give the value with 12bit so in de code is easy, just change the 9bits resolution of the ds fot the 12bits of the ds Hello Peter this is the point that I was trying explain.
Please read part datasheets as relevant source of informations: Mon Mar 03, 3: Ideal for use in remote sensing applications e. xs1822

Sat Feb 22, I hope that soon I even can help you Thank you Best regards. Tue Mar 04, 7: Previous topic Next topic.
How can I do it? Thank you very much best regards. Thermometer resolution is user-selectable from 9 to 12 bits. Converts temperature to bit digital word in ms max.
