simple test EEPROM emulation (STM algorithm described in the application notes: AN4061, AN3969, AN2594, AN3390, AN4056) for STM32F091
Description in AN4061 from STM.
Changed (compared with the original code AN4061):
- possibility of a larger size of emulated EEPROM (using multiple Flash pages)
- dummy variables prevent overwrite code in Flash by algorithm of EEPROM emulation
Macro PAGE_NB_PVP (in eeprom.h) defines the size of the virtual page.
Eg. For F091 where Flash page are 2kB value 4 gives 8kB.
Size 8kB virtual page gives you the ability to use max. approx. 2k of 16-bit variables.
