This tutorial explains in depthESP8266Flash File System Called as (SPIFFS). There are two ways to store data on ESP8266 one is usinginternal EEPROMwhich is of 512 Bytes but you can write data 1 millions of times (no file system). and Second is use of SPI Flash (64kBytes to 3Mbyte),...

Get functions using EEPROM PUT and EEPROM, you can read and write the EEPROM shown in the program below. In the following example, we will write int and string data to EEPROM and read them through serial input from the user. ESP8266 EEPROM CODE ...
The pairing data is stored in theEEPROMaddress in ESP8266 Arduino core. This project does not use theEEPROMlibrary with data-cache to reduce memory use (directly call flash_read and write). TheEEPROMis 4096B in ESP8266, this project uses max [0, 1408B). ...
In that module, each time I lose connectivity to wifi network I save my data in EEPROM and once connectivity is back, I send that data to gateway and hence EEPROM read and writes are quite frequent in my ESP due to frequent reconnects to the wifi network.Now after some time of use,...

``EEPROM.write`` does not write to flash immediately, instead you must call ``EEPROM.commit()`` whenever you wish to save changes to flash. ``EEPROM.end()`` will also commit, and will release the RAM copy of EEPROM contents. 27 27 28 - EEPROM library uses one sector of flash loc...
