-    Rather than hard-coding the length, you should use the pre-provided length function.
-    This will make your code portable to all AVR processors.

+    CRC algorithm generated by pycrc ( https://github.com/tpircher/pycrc ).
 
 	A CRC is a simple way of checking whether data has changed or become corrupted.
 	This example calculates a CRC value directly on the EEPROM values.
 	The purpose of this example is to highlight how the EEPROM object can be used just like an array.
