Why when I read the valor I move 8 position to the left and add again the temp valor? Mon Mar 03, 3: Multi-drop capability simplifies distributed temperature sensing applications.
Fri Mar 07, 5: I saw that for do it I must write on the byte 4 of the scratchpad I was trying ds122 the write scratchpad 4Eh, it transmit 3 data bytes byte 2, 3 and 4 but all the tieme that I was trying nothing happened.
Of course, you don’t need to use this method, you can use, for example, IntToStr routine from Conversion library: Tue Feb 25, Page 1 of 1. Ideal for use in remote sensing applications e.
Converts temperature to bit digital word in ms max. Hello Peter this is the point that I was trying explain. How can I do it?
Hi, Try source code, I think it will work.
And only one question more to try understand the code: Sat Feb 22, Previous topic Next topic. Sat Dec 29, 7: Mon Feb 24, 2: Ds122 DSPAR communicates over a 1-wire bus, which by definition requires only one data line and ground for communication with a central microprocessor.
The DSPAR digital thermometer provides 9 to 12—bit centigrade temperature measurements and has an alarm function with nonvolatile user-programmable upper and lower trigger points. User—definable temperature alarm ds8122. Users browsing this forum: Mon Mar 03, Complain wrong Brand wrong Model non readable. Wed Mar 05, 1: I hope that soon I even can help you Thank you Best regards.

Thank you very much best regards. Please read part datasheets as relevant source of informations: The display format of the temperature is ‘xxx. 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.
Unique 1-wire interface requires only one port pin for communication. Wed Mar 05, Applications that can benefit from this feature include HVAC environmental controls, temperature monitoring systems inside buildings, equipment or machinery, and process monitoring and control systems.

OWIN / OWOUT Example
Requires no external components. Thermometer resolution is user-selectable from 9 to 12 bits. Alarm search command ss1822 and addresses devices whose temperature is outside of programmed limits temperature alarm condition.
