But it is a HAL … WebMay 29, 2024 · As far as I'm aware, simply overriding the HAL_GPIO_EXTI_Callback function is the way to handle an interrupt, but the pin never toggles. What am I missing here? In STOP mode I believe I should simply place the CPU into STOP mode once and do any processing in an ISR as opposed to, for example, a state machine? Thanks. stm32 arm mbed Share Cite
