Good morning,

I need to manage the internal EEPROM of the STM32L151C6: i found some library function for erasing and programming (DATA_EEPROM_ProgramByte, etc..), but I was not able to find some function for Reading from the EEPROM the previous stored data.

If someone have had the same issue, could give me some advices?

Thank you in advance!

You can directly read from the corresponding address, e.g.

#define SRC_ADDR 0x08080000   memcpy

(&dest, (

void

*) SRC_ADDR,

sizeof

(dest));

It should read just like any other memory within the address space, like RAM, ROM, FLASH

#define SRC_ADDR 0x08080000

uint32_t *mem = (uint32_t *)SRC_ADDR; // Or set a pointer to it, could be a structure
