i'm trying to run a simple blinking led program on my stm32f103c8t6 (after i run it several times before successfully), and it doesn't work, when i fix the delay in 1000 ms the led is always on, when i decrement it to 100, 200, 300 it's working properly, but whenever i go above 400 ms it's not working:

Hello @Monssef and welcome to the community,

"X" Pill board flavors (Blue/Black .. other colors) are not the product of ST. They don't contain genuine STM32 chips for years but just fake ones.

I suggest you to purchase any of official ST boards such as NUCLEO-F103RB containing genuine STM32 MCUs.

    okeyy, but i think all the mcu chips are manufactured by ST because i got already one in a custom pcb and i will rerun the same program in it (even i will struggle to access the pins because i have only the interfaces needed in my project)

    thank you !
