Wurth Sensor Arduino Libraries

I am trying to get the arduino libraries for the Wurth Sensors compiling in Particle Workbench.

I am getting a fatal error:

In file included from ./inc/Particle.h:5,
from ./inc/Arduino.h:11,
from src/ArduinoPlatform.h:37,
from src/WSEN_ITDS_2533020201601.h:31,
from src/WSEN_ITDS_2533020201601.c:25:
./inc/application.h:33:10: fatal error: chrono: No such file or directory
33 | #include
| ^~~~~~~~

I cant see anywhere in the library files where this include is located and i cant seem to find any reference to a chrono library using find libraries.
Apologies if this is a simple question, I’m quite new to Particle and the Arduino ecosystem.

Many thanks

In file: WSEN_ITDS_2533020201601.c in line 32 hange
To either Particle.h or Arduino.h and then try again

Hi James,

this looks to be down to the build system a similar post Chrono: No such file or directory suggests a workaround in addition to the above header file change is to rename the WSEN_ITDS_2533020201601.c file to .cpp extension so it will be built as C++ rather than C.

I did this quickly on your sources and it threw up a bunch of errors relating to the inclusion of the ArdruinoPlatform.cpp and .h which gets you a bit further. These serve to wrap the lower level wire I2C API and may need some minor refactoring to align with the Particle DeviceOS I2C API - see Particle Wire (I2C)

You can check against a similar library published to Particle to see how this is handled for example SparkFunMMA8452Q (community library)

Hope this helps,

Sorry my fault, didn’t realize that ArduinoPlatborm is in SRC already

looks like didn’t like #define TIMEOUT 1000 in ArduinoPlatborm.h (line 30)
( maybe it’s conflicting with some other definition of TIMEOUT )
I successfully build over OS2.0.1 getHumidity example from /WSEN_HIDS/examples/getHumidity/ folder and you can find it here:

I just renamed #define TIMEOUT 1000 to #define TIMEOUT2 1000
replaced #include <Arduino.h> to #include <Particle.h> in ArduinoPlatform.h (line 30 and 37) changed TIMEOUT to TIMEOUT2 in ArduinoPlatform.cpp (line 70)

here is an measure_temperature.ino example from /WSEN_ITDS/examples/measure_temperature/ as looks like this is the correct one which you are interested on:

Hi @JamesP,

thanks for the additional pointers @dreamER.

I have tested a project archive bringing it all together for a building solution on OS 4.0.0 for the ITDS sensor including the various adjustments and will share it with you. I don’t have a sensor but hopefully it works on your hardware.

Hi @dreamER & @gcl
Thanks for your prompt help with this issue. I have got these libraries compiling now under OS4.0.0
for b5som and receiving some valid data back from the senor :grinning:
Best regards
