I haven't done anything with the hats, but I do have a few bits of I2C code that go along with the driver modifications I posted a little while back.
The first does a little lightshow on a square LED array from Adafruit: http://cs.drexel.edu/~bls96/plan9/lightshow.c The second talks to the MMA8451 3-axis accelerometer: http://cs.drexel.edu/~bls96/plan9/mma8451sa.c This latter one illustrates the subaddressing features. BLS
