WebApr 22, 2024 · Write to and reading from the EEPROM In a first, simple example, we write three byte values to the EEPROM and then read them from the EEPROM. You initiate the writing process with Wire.beginTransmission (). In the next step, you use Wire.write () to pass the memory address at which you want to store the value. Reading from the EEPROM basically follows the same three step process as writing to the EEPROM: 1. Send the Most Significant Byte of the memory address that you want to write to. 2. Send the Least Significant Byte of the memory address that you want to write to. 3. Ask for the data byte at that location.
