please help me.

thanks.

What like static const int array[] = { 1, 2, 3, 4, 5 }; ??

[Mrohi]

yes dear Clive this my code and SETV is global veriable uint16_t. uint16_t SETV = 0 ;

I need to store this value in SETV after setting by user key up and dn.

in my circuit have 3 input key (1) UP (2) DN (3) SET.

UP key AND DN key is setting up and down and SET key is for store data in flash.

I don't know the sectors number in stm32f030k6t6.where to store and I don't know erase ,read write HAL instruction function

please help me thanks a lot.

I need to store value 0000 to 9999 .

/////-----------------------INTERUPT FUNCTION FOR SET KEY UP +1 AND -1 DN --------------------------

  void KEY (void)

  {

  if (HAL_GPIO_ReadPin(UP_GPIO_Port,UP_Pin)) /// press. up key +1

   {

  SETV = SETV +1;

   LD2ON;

       DT10;

            }

   else

  {

       LD2OFF;

   //INV = ADV1 ;

  }

  if (HAL_GPIO_ReadPin(DN_GPIO_Port,DN_Pin)). /// press down key for -1

    {

    SETV = SETV -1;

     LD2ON;

     DT10;

    }

     else

    {

     //INV = ADV1 ;

    LD2OFF;

           }

  }

///--------------------------------------- END INTRUPT KEY FUNCTION ---------------------------------------------------------------

I'd imagine much of the specifics for the part are covered in the Data Sheet or Reference Manual. I'd probably use the last sector at the end of memory, and shrink the size available to the linker. You'll need to fetch the value from memory rather that use a static definition for the value in the code.
