i set as attached files, save and it generate codes by itself,

then add codes for blinking and then building ,

finally debugging ...

no blinking at all ...

Hello,

3rd parameter of HAL_GPIO_WritePin should be GPIO_PIN_RESET or GPIO_PIN_SET (0 or 1)

If I understand well, you're doing test=0 and then test = -test which is always 0.

There is another function that might interrest you: HAL_GPIO_TogglePin, please have a look.

Good luck.

Thank you let me try this

Dear Mike i did it as attached files ,

then debug and it continue blinking (red /green...) it means continue uploading?

How long it take for debugging?

Am i forget any setting ?

The LD4 led keeps blinbking RED/GREEN when debugging. That is normal.

You should be able to go step by step.

Dear Mike I upload all files in zip here :

Thank you for helping in advance

Thank you.

So problem is that you've selected the HSE as input for the PLL when on the board SB12 and SB13 are not closed.

So you have 2 options:

1) select the HSI as input for the PLL:

RCC_OscInitStruct.OscillatorType = /*RCC_OSCILLATORTYPE_HSE|*/RCC_OSCILLATORTYPE_HSI;

/*RCC_OscInitStruct.HSEState = RCC_HSE_ON;*/

RCC_OscInitStruct.HSIState = RCC_HSI_ON;

RCC_OscInitStruct.PLL.PLLState = RCC_PLL_ON;

RCC_OscInitStruct.PLL.PLLSource = RCC_PLLSOURCE_HSI;

or

2) close SB12 and SB13.

Hope that helps
