DS18B20 and onewire and dallas libraries, from web browser

Troubleshooting
1

Hi friends,

I am attempting to use the OneWire lib, and Spark-Dallas-temperature lib from the browser platform to get the DS18B20 water proof temperature sensor to work. The thing is i have it working in a different script than i am working on now, but when i try and copy it over verbatim i get the following error message;

lib/spark-dallas-temperature/src/spark-dallas-temperature.h:27:36: fatal error: ../OneWire/OneWire.h: No such file or directory
     #include "../OneWire/OneWire.h"

I vaguely remember having a similar issue when i got the sensor working initially but cannot remember how i resolved it. Here is the code i am trying to get to compile. Thanks in advace

i changed your

#include "../OneWire/OneWire.h"

I am still having this issue, i have tried changing the include statement a few different ways.

From the reply i see above the only thing different is the removal of the #include OneWire statement, is this correct?

@jjlee32 I’m using the same lib in a working project and it’s included like this: #include <OneWire.h>

i just compiled your sketch
with

#include <OneWire>
#include "spark-dallas-temperature.h"

i included the spark-dallas-temperature into my sketch see photo
