I can change Packs from the Project Properties. Note that I imported from v1.8.1 but AS7.0 has decided to use DFP 1.3.300 If you Add an "Arduino Library" to an AS7 project, it gets copied to your application src directory. The application just consists of "sketch.cpp" src/libraries/Wire and headers in include/libraries/Wire When AS7.0 imports a sketch it puts any "included" libraries into the ArduinoCore e.g. I"C:\Users\David Prentice\Documents\Atmel Studio\7.0\santos_Wire\santos_Wire\santos_wire\.\ArduinoCore\include\variants\standard" I"C:\Users\David Prentice\Documents\Atmel Studio\7.0\santos_Wire\santos_Wire\santos_wire\.\ArduinoCore\include\libraries\Wire\utility" I"C:\Users\David Prentice\Documents\Atmel Studio\7.0\santos_Wire\santos_Wire\santos_wire\.\ArduinoCore\include\libraries\Wire" I"C:\Users\David Prentice\Documents\Atmel Studio\7.0\santos_Wire\santos_Wire\santos_wire\.\ArduinoCore\include\core" I think that before trying to test the Arduino IDE 1.8.9 it would be easier you sendind me the content of directories boxes of your project in oder to compare with mine, found below. Could not rebuild the solution because of the same error messages I went back to the Aduino IDE, compiled the sketch and searched the compiler messages. It seems to me that at this time Wire.h and Wire.cpp were seen by AS7 but it stumbled at the 'TwoWire" class. Interestingly, I could not locate TwoWire.h, TwoWire.cpp or TwoWire.c in my computer, although I was possible to compile the original sketch in the Arduino IDE.

What is the procedure to build this code in the AS7 environment? I was under the impresssion that when I create a project from Arduino Sketch, AS7 would take care of handling the #include instructions. The change of #include by #include "Wire.h" did not improved the situation. When I tried to build the solution I got the following error messages: End of Auto generated function prototypes by Atmel Studio Beginning of Auto generated function prototypes by Atmel Studio
#Arduino wire library warning code
*End of auto generated code by Atmel studio */ *Begining of Auto generated code by Atmel studio */ Created a new project from Aduino Sketch, board Arduino/Genuino Uno and device atmega328. Then I closed Arduino IDE and opened the AS7.

It was posible to complie it without any aparent problem. Initially I copied the master_write.ino i2c example to another folder.
