Error unknown typ name 'DS18B20'
-
Hi
I downloaded from your link
https://www.arduinolibraries.info/libraries/ds18-b20
But i don't have a board so don't know if it actually works.
It does complain about me not having
#include "Arduino.h"
#include <OneWire.h>but that is expected. The actual .h and .cpp seems happy enough.
I goggled the use of
DS18B20::DS18B20(const char* address)
to see what they would put as adresss but could not find a single example of that.
But plenty of DS18B20 examples otherwise@mrjj
now i removed the .h and .cpp filei just downloaded the libraries again and i got the same problem like in the first picture. why dont you have
#include "Arduino.h"
#include <OneWire.h>
and what did you do that you dont get the error unkown type name "uint8_t"
the error is still hundreds time here. -

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?
@AlexKrammer
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.-
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?
Yes if it has that chip then yes.

@mrjj
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>
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.
How did you solve that problem? -
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. -

@mrjj
that to files OneWire.h and OneWire.cpp include also like DS18B20 as existing File?@AlexKrammer
Yes but im not sure it will just work with a pi board. -
@AlexKrammer
Yes but im not sure it will just work with a pi board.@mrjj
its even dont work on my windows pc ^^ -

@mrjj
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.
@AlexKrammer
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 ? -

@mrjj
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.
@AlexKrammer
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.

@mrjj no but much more ^

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.
