MKR1010 EEPROM not supported. Any alternatives?

Official Hardware MKR Family MKR WiFi 1010
1

Hi, I have just findout that mkr1010 is not supporting EEPROM library. At least on my Arduino IDE i get message:

#include <EEPROM.h>

                   ^

compilation terminated.

exit status 1
EEPROM.h: No such file or directory

Also tested with latest night build

Is there a way to fix it? Project is quite urgent. Is there a fast way alternative?

My goal is to write simple Serial Configurator where user can simply type in USB/COM Terminal and configure SSID and Password

I wanted to save and restore these data using EEEPROM. Any ideas how I can do it, while there is no support for this Lib?

Thanks in advance!

this applies to all SAMD boards. google "Arduino Zero EEPROM"

I'm glad to answer my own Question :slight_smile:

Alternative in MKR1010 WIFI Board for EEPROM will be FLASH STORAGE

Hope it will help someone

why not the EEPROM emulation library?
