Is your STM supported GitHub - stm32duino/Arduino_Core_STM32: STM32 core support for Arduino

is your config set for board used leds? ...

my problem is solved

actually the problem was with stmboard model ,i purchased stm32f103c8 but owner sent me stm32f103c6. i haven't noticed that , and also i was not thinking on that level that change in flash size will make this problem. Ty

For simple LED flashing, you typically don't need much Flash.

However, there are regularly big problems when the STM32F103C8 or STM32F103C6 is on a board called Blue Pill, because only counterfeits and bad clones have been installed there for a long time. There are a lot of questions here in the Community on this very topic, but ST can of course only give answers on the original components.

Good luck!

Hello ARaul.2,

Glad I could help,

So, as I could understand you have configured stm32f103c8 instead of stm32f103c6.
