I need to store historical data in my meter with profile generics. I can read for now current values in profiles but, once read, the data is not stored so it can be read later again. The problem is that my micro does not support files and I don't have an EEPROM. I am using a STM32 microcontroller.
How can I do this without files or EEPROM?
Is there any examples for ANSI C that implement this alternative way?
