Google a part, say ''STM32F405RG''

Go to ''Design Resources'' tab, Find ''EEPROM emulation'' in software downloads

Volia!

Although to be honest using 16K, or larger, flash elements to do this isn't very efficient, and has non-realtime appropriate side effects.

Thanks Clive1, I'm just doing some testing and learning.

I was looking for but could not find a good link.

The site is quite a nightmare to navigate, it was reconfigured last month, but stuff is non obvious, and not titled in a way that Google, Bing, etc would naturally lead you to the right spot. Ideally you'd want it to say AN3969 somewhere on the download page itself?
