WebApr 26, 2024 · EEPROM. Short for electrically erasable programmable read-only memory, EEPROM is a PROM that can be erased and reprogrammed using an electrical charge. … 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. See more Our example sketch will simply take any byte that comes in over the serial port and write it to the EEPROM, keeping track along the way of how many bytes we've written to memory. … See more Writing one byte at a time is fine, but most EEPROM devices have something called a "page write buffer" which allows you to write multiple bytes at … See more Here's an example sketch to write some data to the EEPROM.
