EEPROM implementations that are seamless between 8 and 32 bit

By dave on July 22, 2018

If like me you use both 8 bit AVR and 32 bit boards, you’ve probably already noticed that there’s no EEPROM support on some 32 bit boards. I think that’s quite unfortunate as EEPROM storage is very useful for many applications. Relying on memory backup like many systems today do, is nowhere near as reliable (a flat battery loses everything). Further, I’ve even seen discussions where people suggest using an area of program Flash as an EEPROM, I don’t personally like it as flash write cycles are generally an order of magnitude lower than EEPROM, but it’s now supported via the EEPROM class wrapper.
