EEPROM on STM8L001

[Amampondo]

Hello

I wonder if there is some example code available on how to use the Data EEPROM in the 8pin STM8L001J3.

I did successfully work with the internal Data EEPROM on the STM8L051, but no success on the SO8. The address I used is 0x9BFB (in contrast to 0x1000 on the STM8L051). There is no error when debugging the code in ST Visual Develop/Cosmic, but the content of the bytes I want to alter does not change.

Best regards

TO WHOM IT MAY CONCERN:

Unlike all official examples show and all documentation implies, it is needed to address the Data EEPROM as if it was Program EEPROM. Hence the following code works:

// Do this once, e.g. after power-up:

FLASH_DeInit();

FLASH_SetProgrammingTime(FLASH_ProgramTime_Standard);

// Do this for each write access

// Unlock the Flash

FLASH_Unlock(FLASH_MemType_Program);

// copied from FLASH_ProgramWord: "Enable Word Write Once"

FLASH->CR2 |= FLASH_CR2_WPRG;

// Do what you need, e.g.

FLASH_ProgramByte(EEPROMSTARTADDR,  "yourDataByte");

// ...

// Finalize

FLASH_Lock(FLASH_MemType_Program);

"EEPROMSTARTADDR" in my case is #defined as 0x9FC0
