To write byte to EEPROM we need two commandsĪrduino Eeprom Library24681012141618202224262830323436384042 * EEPROM Write * Stores values and string to EEPROM. I found no library for it, so I created a small sketch with few functions to show how the i2c_eeprom_write_page.

I got my hands on an AT24C256 (256 kbit = 32 kbyte serial EEPROM). The playground is a publicly-editable wiki about Arduino.I found no library for it, so I created a small sketch with few functions to show how the i2c_eeprom_write_page and i2c_eeprom_read_byte functions work. This can be done in several methods, using I2C and Serial, to list a few. Having Arduino-Arduino communication can be useful for many projects, such as having one Arduino to run motors and having another sense the surroundings and then relay commands to the other Arduino.Serial Eeprom Programmer Arduino Tutorial.
We also discuss on writing string into EEPROM and reading it. ESP8266 have 512 bytes of internal EEPROM, it is useful when you want to store some settings, such as IP address of server, WEP key, SSID of WiFi. In this tutorial we will see writing data to EEPOM and reading from EEPROM.
