    Yes, it seems that way looking over the examples.

    are you using the
    DS18B20::DS18B20(const char* address) version or the other version using uint pin ?

    Now i removed the
    #include "Arduino.h"
    #include <OneWire.h>

    and added #include <stdint.h>

    But now i receive the error massage with OneWire again.
    How did you solve that problem?

    The second fault is that the .cpp produced a lot of errors too.
    I think it depends on the OneWire file.

      Hi
      That include file comes from
      https://www.pjrc.com/teensy/td_libs_OneWire.html
      But im not sure that works with a RaspberryPi directly.

        that to files OneWire.h and OneWire.cpp include also like DS18B20 as existing File?

          Yes but im not sure it will just work with a pi board.

              There are still error. i dont know, why you dont receive that errors respectively when you try to compile the code, why its work. if i try to run it, there are hundreds of error messages.

                Well i didnt download and added OneWire to see. Maybe why.
                Just checkout DS18B20 as question started with.
                I dont have a board to test on so i would never be able to run it anyway.

                Thats just #include <stdio.h> it complains about.
                Very odd the .h does not include that.

                Also, you do understand that these libs are meant to be used ON the board.?
                They can never read a sensor on a pi board where apps run on win pc and have the pi board connected via USB
                or similar.
                But you do seem to have a raspberry Debian running so you are compiling directly on the board, right ?

                  Now I includes #include <stdio.h> in ds18b20.cpp but nothing changed.
                  the error C1083 does not depend on stdio.h, does it?

                  yes i have both systems running.

                    Ok. Good. Just checking
                    No that error comes from some missing .h file. As it shows.
                    From the utils folder
                    https://github.com/PaulStoffregen/OneWire/tree/master/util
                    so you should add those too it seems.

                      oh thanks. that i missed. but its funny. i have the same errors on windows and raspien.
                      i think it dont depend where to compily. The only different i think will be, on raspberry will the outputs work. Dont you think?

                        Well it should give same errors from compile on both systems if they are related to missing includes.
                        What are the errors now ?

                        Still bitRead etc ?

                        And yes, the biggest difference is when you run it. On win pc there would be no hardware to to talk to.

                            Hi
                            Seems to come from
                            https://www.arduino.cc/reference/en/language/functions/interrupts/nointerrupts/

                            So I think we are down the wrong path using this with a pi board as it seems tied to
                            Arduino.

                              is it possible to create a own library to convert the input of the sensor in a temperatur?

                                    I think you need a c++ lib then like
                                    https://github.com/TeraHz/DS18B20
                                    to interface with the hardware.

                                      @mrjj to interface with the hardware ill use wiringpi. thats work good. i can turn on und off leds and i can read pins.
                                      how does this lib work?

                                          Heh yes but on this is says it should work with PI
                                          and it has more includes.
                                          So maybe this will actually work once we find out what that address should be :)
