The Arduino ShiftInOut is a Serial to Parallel Shifting-Out and Parallel to Serial Shifting-In library.
The hardware bindings for the shifting are provided as C++ template arguments. Currently supported:
The DigitalRead and DigitalWrite functions can be overwritten if faster methods are available (also through C++ temmplate arguments). The Out-of-the-box implementation maps to the default implementation of DigitalRead and Write.
