I am trying to interface ds18b20 with arduino. I have downloaded the dallas temperature libraries but during compilation it is showing some errors in the DallasTemperature.h.
I have taken the code from http://www.hobbytronics.co.uk/ds18b20-arduino.
Some of the errors are as follws:
1.Syntax error due to some brackets ( )
2._onewire not declared anywhere.
Please tell whats the problem or some alternative code.
I thought that code was junk. It's just possible that it isn't, but this definitely isn't
Read it carefully, note that that there are two programmes involved, and note the wiring.
First of all, with 1 Post and 0 Karma, it is obvious you are a Newbie. Here's a tip; ALWAYS BEGIN YOUR SEARCH FOR A LIBRARY OR CODE EXAMPLES OR ANYTHING ARDUINO RELATED WITH A GOOGLE SEARCH CONTAINING THE KEYWORDS "ARDUINO [SPACE] [SUBJECT]". This will return a search looking something like this:
Then look at the top of the search for a link with the keywords "Arduino Playground", under which you will see a link that looks something like this:
[url=Arduino Playground - HomePage [url=http://(look for these important words in the URL ".arduino.cc/Learning"
Then CLICK on the [Playground] link to go to a page that looks like this:
Arduino Playground - HomePage] playground.arduino.cc/Learning/OneWire (look for these important words in the URL ".arduino.cc/Learning"
Then CLICK on the [Playground] link to go to a page that looks like this:
Arduino Playground - HomePage] (look for these important words in the URL ".arduino.cc/Learning"
Then CLICK on the [Playground] link to go to a page that looks like this:
Arduino Playground - HomePage] playground.arduino.cc/Learning/OneWire (look for these important words in the URL ".arduino.cc/Learning"
Then CLICK on the [Playground] link to go to a page that looks like this:
Arduino Playground - HomePage
SCROLL DOWN until you see something that looks like this:
The latest version of the library is on Paul Stoffregen's site.
Now this is the important part; NOTE THAT SOME OF THE WORDS ARE "arduino green" (THESE ARE LINKS)
Note the one with the of the Library , like this :
The latest version of the library is on Paul Stoffregen's site.
Notice how this link includes the name of the author of the library which is itself a link; whch when you click on it takes your here:

So why am I telling you this ?
Well, because EVERYTHING ON THE ARDUINO SITE has already been tested and when we do this we know we are not getting garbage. Unless you want to be back here posting a plea for help again , try following the above. It doesn't guarantee you will never have problems, it guarantees you will have fewer UNNECESSARY problems, like the one you have now. I have used the library at the link I recommended and it works. I don't know why you have a problem with the library you are using because I
don't think I have tried it.
