1.How is this #define HALL3_CREATE_MAP(v) working?

2.What is this "Alpha state" "A branch state" "B branch state" "C branch state".

Thanks is advance.

HALL3_CREATE_MAP Should be defined in the header files. It assigns a GPIO value to a pointer inside of a structure.

The code works as a state machine assigning a set of tasks to be completed one by one. The alpha states are initialization states. The branch states, are just that, branches of the code.

Cody

Additionally, here is a helpful post that describes the branches in greater detail.
