I am reading "Embedded Motion Driver 5.1.1 Tutorial". I don't understand what is chip, body and device frame? I guess they are different kinds of coordinate. Can anybody give me more explanation or examples to illustrate what is chip, body and device frame? Thanks a lot!

Chip and Body frame both refer to the devices "reference frame" which is the X, Y, and Z sensor axes. Device frame refers to an X, Y, Z relative to the end product, such as an Android Phone's screen orientation, which may not match that of the sensor. A world-frame coordinate system is relative to gravity, and North references.
