Download Library Dallastemperature.h

Note the above links are the source code at the 3.7.6 release, which I assume you're using since I seem to remember you use Library Manager and that's the most recent version available via Library Manager. There has been significant work done on the library since that release:
I have no idea why this keeps happening, as I have opened an example sketch that uses this same library, and i don't get the same error message when verifying - so i definitely DO have such a file, and it must be in the right place!
problem solved, after trying it for myself, I figured out that OneWire is a separate library also created by dallas semiconductors, you need to install that library as well, also you have a lot of errors
Post a link to where you got the MAX31850_DallasTemp and MAX31850_OneWire libraries from. Please use the chain links icon on the toolbar to make it clickable. Or if you installed it using Library Manger(Sketch > Include Library > Manage Libraries) then say so and state the full name of the library.
It adds the library folder that contains that file to the list of include search paths. Among other criteria, the Arduino IDE normally gives include priority to the folder name that matches the include file name so that's why OneWire/OneWire.h was getting include priority over MAX31850_OneWire/OneWire.h.
PS. If you do edit the libraries with that line be sure to remove it after you're done. Otherwise you might forget you did that and have a lot of confusion later when you try to use the library and it won't compile with this strange error message!
Yes, the sketch and any .cpp file that includes the .h file will have those defined. But keep in mind that only tells you that a file from the MAX31850K_DallasTemperature library was used. It does not tell you that none of the files from the DallasTemperature library were also used.
Arduino Library for Dallas Temperature ICsUsage This library supports the following devices : DS18B20 DS18S20 - Please note there appears to be an issue with this series. DS1822 You will need a pull-up resistor of about 5 KOhm between the 1-Wire data line and your 5V power. If you are using the DS18B20, ground pins 1 and 3. The centre pin is the data line '1-wire'. We have included a "REQUIRESNEW" and "REQUIRESALARMS" definition. If you want to slim down the code feel free to use either of these by including #define REQUIRESNEW or #define REQUIRESALARMS at the top of DallasTemperature.h Credits The OneWire code has been derived from Miles Burton [email protected] originally developed this library. Tim Newsome [email protected] added support for multiple sensors on the same bus. Guil Barros [[email protected]] added getTempByAddress (v3.5) Rob Tillaart [[email protected]] added async modus (v3.7.0) Website You can find the latest version of the library at =Dallas_Temperature_Control_Library License This library is free software; you can redistribute it and/or modify it under the terms of the GNU Lesser General Public License as published by the Free Software Foundation; either version 2.1 of the License, or (at your option) any later version.

Some platforms do not implement yield so you can remove the call to it from the code of the library. Calling yield passes control to other tasks, if you do not have other tasks, it is redundant anyway.
Looks like something could be broken in the Library Registry backend (it is in the middle of a major overhaul, so some breakage is to be expected). Weird stuff is happening there with the library.json version being different to the library.properties and the header version, and not seeming to match any of the versions.
In the mean-time you can either use -Temperature-Control-Library/archive/3.8.0.zip to directly reference the library zip file, or use milesburton/Arduino-Temperature-Control-Library#3.8.0 if you have git installed/configured.
in my case i use Dallastemperature 3.8.0 and a pullup resistor 47K. this code work with lorawan protocol in cubecell board and cubecell capsule. check library version and check wires. my code works on lorawan otta, you need to put yours aplicattion keys.
Hello, greetings from Mexico.
Here I bring you what worked for me and where the error seems to be because the DS18B20 sensor does not work initially.
If you have previously worked with the DS18B20 sensor, it is obvious that you must already have the onewire.h library installed. This is where the error occurs. When you install everything related to the Cube Cell, there are some libraries edited to work with it, and one of them is onewire.h. If I remember correctly, this is here:
C:\Users\Luis\AppData\Local\Arduino15\packages\CubeCell\hardware\CubeCell\1.1.0\libraries
I am using one of the standard examples from Arduino library. My wiring is also correct as the same setup works perfectly on ESP8266. Also I tried to use different pins, but again same behaviour. I have 2 boards and they both seems to have same issue.
I was spinning my wheels trying to decide if the direct register access register routines used by this library were creating some hardware problem specific to these boards. (Time to get out the data sheet, or so I thought.)
Footnote: After making changes to ensure that interrupts were always enabled before calling the delay functions, I tested with the DS18x20 example in the OneWire library. Badda-bing, Badda-boom.
(I think your plan for replacing the calls to the delay functions is preferable.)
Dallas Temperature is a hardware-specific library that handles lower-level functions. It must be paired with the One Wire Library in order to communicate with any one-wire device, not just the DS18B20. Install this library as well.
When the Dallas Temperature library is initialized, it scans the bus for all sensors that share the same bus. It considers the entire bus to be an array of sensors and assigns each one an index. As a result, we can identify each sensor by its index and read temperature.
The sketch begins by including libraries, declaring the pin to which the sensor bus is connected, and creating a DallasTemperature library object. In the same global scope, two variables are defined: deviceCount stores the number of sensors found on the bus, and tempC stores the temperature read from each sensor.
Finally, when you say "And when I import the DallasTemperature library into Arduino folder like it is supposed to be!?.... and verify again, I get this:" Where did you place the folders? There should be at least 2 folders under Arduino\libraries\ for this program and those are DallasTempControl and OneWire. They are separate libraries that actually work together. In looking at the errors you give above, it looks like DallasTemperature.cpp may have gotten accidentally renamed to DallasTemperatur e.cpp (notice the space)? Check to make sure this isn't just a debug mishap. And I notice up at the top that it looks like the OneWire library may have been placed in the \Wire directory. On my computer at least, the OneWire library is in a folder all by itself in the libraries folder with 3 files and an examples folder in it (keywords.txt, OneWire.cpp & OneWire.h).
Thank you PentairDave, yes you were right, there were two OneWire copies in the wrong directory, but the library also contain the right files. Anyway I removed the files but the error code still looks in some way like the old one. A picture says more than thousand words so I made one which shows what my library directory contains.
