to get rid of the ambiguous error I had to fix two files: M5Atom.cpp and MPU6886.cpp.

In M5Atom.cpp I've replaced this line:

  Wire.begin(25, 21, 100000);

with (note the U at the end):

  Wire.begin(25, 21, 100000U);

and in MPU6886.cpp I've replaced this line:

  Wire1.begin(25,21,100000);

with: (note the U at the end)

  Wire1.begin(25,21, 100000U);

Thanks
Felix
