Hi,
I would like to know that can we write I/O expander address (ex:0x20) as the data in EEPROM.write function?
ex: EEPROM.write(address, 0x20);

Have a google for eeprom.write Or Arduino eeprom for how it all works .

You need to include the library and the data saved in your expression needs to be a byte .
