100Hz was use for testing purposes, the end goal is to have 30kHz as the clock frequency

GPIO is also use for acquire the real pulse generator frequency

Each clock will trigger the SPI to collect 16x2bits of data

Data is combine into a 32bit/uint32

The tableCRC6 follow the BiSS sample code (also here: https://forum.arduino.cc/index.php?topic=517714.0), C example code was also given, the code is altered to MATLAB code
