Error using Adarfruit BNO055 .h .cpp and Adafruit_Sensor.h

Firmware Libraries
1

Hey!
I am trying to use Adafruit BNO055 imu sensor and sending data to my Spark core
I am following the Adafruit guide and downloading the files needed to use the sensor: https://learn.adafruit.com/adafruit-bno055-absolute-orientation-sensor/wiring-and-test
but when I just try to compile the files in my particle dev I get lots of errors, after trying to fix some of them, for example deleted the include “Wires.h” I am still having some errors without any luck of repairing them.

For example, when trying to verify the blinker app when adding the sensor.h files in the Particle build (just adding this line - ‘#include “Adafruit_Sensor_Photon/Adafruit_Sensor_Photon.h”’), I am getting this errors:

32+0 records in

32 bytes (32 B) copied, 7.4688e-05 s, 428 kB/s
4+0 records in

Have you read any thread about porting Arduino libraries to Particle?

A crucial point is #include "Particle.h" (previously #include "application.h")

Adding the include “particle .h” solved many errors, but now I got some new errors.
In the Adafruit_BNO555.cpp file, this lines are shown multiple times:

Wire.beginTransmission(_address); #if ARDUINO >= 100 Wire.write((uint8_t)reg); #else Wire.send(reg); #endif Wire.endTransmission(); Wire.requestFrom(_address, (byte)len);

The error is: Class TwoWire has no memeber send
I tried searching on the forum for solving this import problem with no luck

Thanks for the help

If you change that to

  #if (ARDUINO >= 100) || defined(SPARK)
    Wire.write((uint8_t)reg);
  #else
    Wire.send(reg);
  #endif

it should work, since there is only Wire.write() and no Wire.send().
