The ESP8266 with EEPROM is a low-cost microcontroller for permanent storage.
This is what you need to know about the ESP8266 EEPROM
The ESP8266 is a versatile 32-bit microcontroller from espressif with an integrated WLAN chip. It allows devices to be easily connected to the internet and is widely used for the Internet of Things (IoT).
- EEPROM is a non-volatile memory that allows the ESP8266 to permanently store data even if the device is turned off or rebooted.
- The storage capacity of the EEPROM is 4 kilobytes. There are ways to increase or decrease the available memory.
- The EEPROM memory can be divided into different sectors or blocks to improve the management of the stored data.
- The EEPROM of the ESP8266 is accessed via special functions and commands in the Arduino development environment or using programming languages such as C/C++.
- As with most EEPROMs, the number of write cycles for the ESP8266 EEPROM is limited to several 10,000 write cycles. Therefore, it is recommended to limit the writes to the EEPROM to minimise wear and tear on the memory.
- In order to store files in the EEPROM and to be able to read them from there, the library “EEPROM.h” must be integrated into the main programme. In addition, you must integrate your own data structures.
- The ESP8266 is especially popular for storing configuration data, device parameters, meter readings or other user information.
More info on the ESP8266 EEPROM
Since the release of the ESP8266, new microcontroller versions have been developed, such as the ESP32, which offers additional functions and improved memory capacities.
- The EEPROM of the ESP8266 does not support built-in error correction mechanisms. Therefore, it is important to check the integrity of critical data yourself and implement error correction in the software if necessary.
- Thanks to its inexpensive price and wide range of functions, the ESP8266 is particularly popular with developers and hobbyists.
