WebMay 8, 2024 · Yes, by default, HAL_Delay () depends on the SysTick timer. In most cases when programming STM32 MCUs, the SysTick must have the highest priority in order to avoid deadlocks due to interrupt handlers using HAL_Delay () (which is a bad pattern anyway, but it happens, not only in the code in the question). – wovano.

"WebJun 19, 2024 · GPIO Port X is attached to EXTI line Y to have an interrupt on Port X Pin Y. EXTI sends an interrupt event to the NVIC. NVIC checks if that interrupt of EXTI is enabled, and if it is, it triggers the ISR. Everything is correct here. The problem is, EXTI sends an interrupt event WHENEVER its corresponding event bit is set to 1. " - Gpio interrupt programming in stm32
