It's me again, who commented on your MPU9250 library with the same problem. Now I decided to start using the USFS boards and would be very happy using your library for it. Can you please make the same changes to the Makefile as you did earlier to fix the problem of compilation? For comprehension, this is my error message:

Makefile:33: recipe for target 'MasterTest' failed
make: *** [MasterTest] Error 1
And I also have a question: In MasterTest.cpp, you don't read the Magnetometer values although the class features them. I can still add it with usfs.readMagnetometer(mx, my, mz), right?
Thanks for all your help!
