AT24CXXX EEPROM - ESP32, Arduino, NodeMCU and ESP8266

= Allows write cycles 0 = Inhibits write to the EEPROM WR: Write Control bit 1 = Initiates a write cycle. The bit is cleared by hardware once write is complete. The WR bit can only be set (not cleared) in software. 0 = Write cycle to the EEPROM is complete RD: Read Control bit 1 = Initiates an EEPROM read; RD is cleared in hardware. EEPROM broken #414. Closed isexton opened this Issue Jun 11, 2015 16 comments just bytes modified in in-memory buffer (like EEPROM. write) 3 - bytes located in buffer that differs from actual EEPROM (like EEPROM. update) I think I'll stop using EEPROM in ESP8266 in order not to run out of EEPROM cycles in a few weeks

A working framework for saving configuration parameters to ESP8266 EEPROM. And as an added bonus, you have a structure to expand this to render webpages of your own choosing. To control or monitor your own IoT things visually.

ESP8266 WiFi settings in EEPROM - MySensors Forum

EEPROM. write does not write to flash whenever you wish to save changes to flash. EEPROM. end() will also commit, and will release the RAM copy of EEPROM contents. EEPROM library uses one sector of flash located just after the SPIFFS. Library was adapted to work with ESP8266 by including register definitions into OneWire. h Note that if

Arduino Playground - EEPROMReadWriteLong

In Arduino you call EEPROM. begin(), but in ESP8266 you have to call EEPROM. begin(n), where n is the total number of bytes you will need. And remember that EEPROM have a short life span (by number of writes). You must minimize the number of writes! EEPROM is permanent; you don't need to do nothing.
