you have 128 bytes EEPROM in your micro-controller. how to read or write it depends on compiler you use? tell me what compiler you use?

The eeprom functions are described here https://www.nongnu.org/avr-libc/user-manual/group__avr__eeprom.html

I use a few simplified macro that don't need use of things like (const uint8_t*) in front of the address
