    hi
    I dont have a board so i dont have the Arduino software / libs installed so no #include "Arduino.h" etc.

    the uint8_t comes from
    #include <stdint.h>

    @mrjj i dont use arduino too. Raspberry Pi is what i use.
    The stdint.h is just a standart library or where can i get it?

    If this change remove the error do u thing when i type in a raspberry pin into the constructor e.g. 22 it will work?

      Oh
      I just assume since it had Arduino included and most google searches talked about Arduino :)

      Well i just added
      #include <stdint.h>
      and it knew it.
      So its included on newer compilers.

        Yes if it has that chip then yes.

        And if i create a new class called "CheckTemlerature" how could i use the DS18B20 sensor.
        The first thing to open the constructor with input the Raspberry Pin.
        Second step Funktion getTemp?
        Third step close with destructor?
        Thanks for halp

          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 ?

            I deleted the DS18B20::DS18B20(const char* address) version and try it with your idea. I hope it will work but ill see it tomorrow. Its enough for today.
            Thanks a lot.

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

              and added #include <stdint.h>

              screenshot.png

              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?

                        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.

                                        and what will be the right way. is it possible to use qt for this?
                                        is it possible to create a own library to convert the input of the sensor in a temperatur?

                                          Hi
                                          But do you have such sensor ?
                                          and hook it up to the board like they do here ?
