Hal_systick_callback
WebNote that the BTN_Main function is being called from the SysTick callback function. This function needs to be called inside the ISR handler for the SysTick timer. The HAL_Init initializes the systick timer and the HAL_Delay uses it to work as well. So, let’s open this file (stm32f1xx_it.c) and search for the SysTick handler and call our ...
