/****************************************************************************************************************************
multiFileProject.cpp
For STM32 using Flash emulated-EEPROM
The FlashStorage_STM32 library aims to provide a convenient way to store and retrieve user's data using the non-volatile flash memory
of STM32F/L/H/G/WB/MP1. It's using the buffered read and write to minimize the access to Flash.
It now supports writing and reading the whole object, not just byte-and-byte.
Inspired by Cristian Maglie's FlashStorage (https://github.com/cmaglie/FlashStorage)
Built by Khoi Hoang https://github.com/khoih-prog/FlashStorage_STM32
