> Please Test Any MCU you have and tell me the result.

> [!CAUTION]
> EEPROM Emulation Library is based on <a href="https://www.st.com/en/embedded-software/x-cube-eeprom.html">EEPROM emulation expansion software for STM32Cube</a> .  
> It is not working on Dual pages Sector-Base Flash ( STM32F429II ...)

* Install Library from https://gitea.iotxs.de/RainerWieland/EEE4STM32/raw/branch/master/STM32-PACK/RWD-EEE4STM32.pdsc
* Add and enable it.
* It does not need to any configuration. This Library Select the latest page/sector of the MCU.
* Generate Code.
* Set a buffer for Storing the Data ( array, struct, ...)
* Call EE_Init()
