How do I erase all data in EEPROM in a easy way?
I'am making a RFID-reader and I can save/erase ID if I push down buttons, but I would like to erase all ID pushing down another button. I'am saving the number of ID in place 0 in EEPROM, and i was thinking about just changing the number of ID to zero but in that case I have to change all other functions. I think it's better to just erase all. But how?
