DATA EEPROM on B-L072Z-LWAN

[SStan]

Hello,

I am developing a project based on B-L072Z-LWAN with STM32CubeIDE 1.6.1, I need to write data to DATA EEPROM. I use herring functions:

//Byte write

void EEPROM_WRITE(uint16_t BiasAddress, uint8_t *Data, uint16_t len)

{

uint16_t i;

HAL_StatusTypeDef status = HAL_OK;

HAL_FLASHEx_DATAEEPROM_Unlock();

for(i=0;i<len;i++)

{

status +=HAL_FLASHEx_DATAEEPROM_Program(FLASH_TYPEPROGRAMDATA_BYTE, EEPROM_BASE_ADDR+BiasAddress+i, *Data);

Data++;

}

HAL_FLASHEx_DATAEEPROM_Lock();

}

but when compiling the project it gives me an error for an undefined function:

HAL_FLASHEx_DATAEEPROM_Unlock ();

when changing the function of:

//Byte write

void EEPROM_WRITE(uint16_t BiasAddress, uint8_t Data)

{

HAL_StatusTypeDef status = HAL_OK;

HAL_FLASHEx_DATAEEPROM_Unlock();

status =HAL_FLASHEx_DATAEEPROM_Program(FLASH_TYPEPROGRAMDATA_BYTE, EEPROM_BASE_ADDR+BiasAddress, Data);

HAL_FLASHEx_DATAEEPROM_Lock();

}
