 I have test this library on Arduino Uno/Mega2560/Due, maybe support other AVR/SAM3X MCUs.
 You can search keywords like "Arduino Mega2560 pinout" to find pinout mapping with your board like this:
 
-First, you need connect your slave module to arduino, SCK to SCK, MISO to MISO, MOSI to MOSI, Reset to Reset
