New web ide lib manager will not compile Onewire library

Hi All,

I have been using the OneWire library and Spark-Dallas-Temp to compile with no problems. This am when I tried to include Blynk the IDE made me move to the new library manager.

Now the IDE cannot find the Onewire and won’t compile.

Here what the error message is:

In file included from /src/onewireds18b20.cpp:5:0:
lib/spark-dallas-temperature/src/spark-dallas-temperature.h:27:36: fatal error: ../OneWire/OneWire.h: No such file or directory

My messy code follows:

The problem is the double dot ../ in the spark-dallas-temperature lib.
The library needs updating that way or the build environment has to me tweaked to accept these.

Alternatively you can use the Particle OneWire library and the DS18 example that comes with it.


Can I hack in this change? Where would I find this library file ?


You should find a GitHub icon next to the library name in Web IDE.


I will poke into GitHub. How do I get the IDE to reference the change do I have to fork the lib?

Also I did try the Particle OneWire lib before but would not compile in the previous IDE



I spoke wrote wrong. I could get the Particle OneWire to compile but could not read any data from the DS18B20 sensors.

I just recompiled it. maybe it’s time to put a logic analyze on the wire and see what the photon is doing with this build. The same hardware works in the other spark-dallas-temperature library so this gets rid of the missing pullup and other stupid gotchas


You’d need to for the and upload as private lib.
But since it’s only two files, I’d just remove the lib and instead add two file tabs to your project, call them the same as in the lib and copy paste the content, correct the mistake and you’ll be fine.
