WebFeb 28, 2024 · EEPROM Read Another function to consider is that of data recovery of course. For this we will use the EEPROM.read function, which will allow us to read bytes from EEPROM memory. int value = EEPROM.read(addr); As with the write function, we will have to indicate the address to read (addr), and the data will be saved in the variable value. WebNote: Reading from the EEPROM does not degrade the memory. You can read an EEPROM address as many times as you want. TIP: To extend EEPROM life first read the contents to be written - if it is the same as the value you want to write, then don't write to it! TIP: Each time you write a set of data - read it back to ensure it was written correctly ...
