I had to upgrade to Arduino Grand Central M4 ( running SAMD51 ) due to large code and demanding memory . I know SAMD51 does not have a classic EEPROM but it still has NVM for user data storage between power offs.
In regular Uno I used to use but this file is hardware specific and does not compile for SAMD51 ( compiler file not found error occurs ) . I was wondering if there are libraries for accessing NVM user page ( obviously without messing with its first 32 bytes of registry )
#include <EEPROM.h>
