EEPROM_Clear.ino
For SAMD21/SAMD51 using Flash emulated-EEPROM
The FlashStorage_SAMD library aims to provide a convenient way to store and retrieve user's data using the non-volatile flash memory
of SAMD21/SAMD51. It now supports writing and reading the whole object, not just byte-and-byte.
Based on and modified from Cristian Maglie's FlashStorage (https://github.com/cmaglie/FlashStorage)
