SparkFun Electronics Forum

I have not been able to find reference on how to use EEPROM with Sparkfun SAMD 21 Mini Breakout.

#include <EEPROM.h> flags as a compiler error.

Obviously that library is unsuitable, but I have been unable to find how to write and read to the EEPROM area of non volatile memory.

Any assistance would be appreciated.

The SAMD21 doesnt have a dedicated EEPROM.
However, there is reserved flash memory with an EEPROM emulator which can be accessed and programmed similar to EEPROM.

Have a look at Atmel's application note about this here:
