Arduino for STM32

Hello everybody,

According to what I've read and misunderstood, in an STM32F103C8, there would be no EEPROM but there would be a way to save a few bytes in it. My need is reduced to one byte.

Can you tell me how to save it (write every 15 days, or even less) and read every day.

Thanks for your help.

Pierre.

Built-in eeprom library uses emulated eeprom in flash memory. Usage is the same as with Arduino AVR (Uno, micro, nano, etc) boards.

Downside - it uses 2 pages of flash memory so with F103C8 it takes 2kB out of flash just to store 256B of data.

Tank you very much "GonzoG" for this explanation and example.

Sincerely.

Pierre.
