 The heart of the FastLED library is the fast pin accesss.  This is a templated class that provides 1-2 cycle pin access, bypassing digital write and other such things.  As such, this will usually be the first bit of the library that you will want to port when moving to a new platform.  Once you have FastPIN up and running then you can do some basic work like testing toggles or running bit-bang'd SPI output.
 
-There's two low level FastPin classes.  There's the base FastPIN template class, and then there is FastPinBB which is for bit-banded access on those MCUs that support bitbanding.  Note that the bitband class is optional and primarily useful in the implementation of other functionality internal to the platform.
