Stm8s003f3 internal flash debugging

Here's a record , Convenient for later use

View the documentation manual ,data eeprom The starting address of is 0x004000, This is used to store some, such as version number ,ID, Or use this flag bit

Sample code ：

typedef enum {
    FLASH_MEMTYPE_PROG      = (u8)0x00, /*!< Program memory */
    FLASH_MEMTYPE_DATA      = (u8)0x01 /*!< Data EEPROM memory */
} FLASH_MemType_TypeDef;

int main()
{
    u32 addr = 0x4000;

    CLK_HSIPrescalerConfig(CLK_PRESCALER_HSIDIV1);

    while(1)
    {
        FLASH_Unlock(FLASH_MEMTYPE_DATA); // according to MemType Fill in 

        FLASH_EraseByte(addr);

        FLASH_ProgramByte(addr, 0xa5);

        if(FLASH_ReadByte(addr) == 0xa5)
        {
            ;
        }

        FLASH_Lock(FLASH_MEMTYPE_DATA);

        delay_ms(500);
    }
}
