Virtual EEPROM for F0

[retro]

Hello,

Please be patient, I am quite new to this. So, I would like to implement a virtual EEPROM for my F042k6 mcu, i saw that there is the https://www.st.com/en/embedded-software/x-cube-eeprom.html but it only seems to cover STM32G0 Series, STM32G4 Series, STM32L4 Series, STM32L4+ Series, STM32L5 Series, and STM32WB Series. Is there any other way of doing this? with the Hal Driver? does it still work with x-cube? Do you guys know any good examples?

Thank you 🙂

There is also "EEPROM emulation in STM32F0xx microcontrollers (AN4061)" but it predates HAL quite a bit. Probably still works just fine.

I don't know of anything pre-built for this with the HAL library for the F0. It would be a good first project for someone to learn on.

Figure out how you're using EEPROM, if you are continually writing values you should probably add an external device, or think about NVRAM/BKPRAM

For user configuration, changed relatively infrequently, consider just using a FLASH sector, and journalling a configuration parameter structure across the entire sector, erasing only when it is exhausted.

I only need to store some calibrations and some settings for the communication bus. Would not be more than 40bytes - it would only be written to rarely and read each time the device is turned on.

Thank you for this, I will have a look over it

I downloaded it, and I can't compile because of static FLASH_Status EE_Format(void); error: unknown type name 'FLASH_Status'. In the example I cannot find where FLASH_Status is defined

Hi retro.

have you found the soloution ?

I'm facing the same problem with stm32f412RET.

'FLASH_Status' doesn't seem to be ceclared.
