WebI enable external interrupts for the button using the function provided in the STM BSP package: BSP_PB_Init (BUTTON_KEY, BUTTON_MODE_EXTI); The external interrupt for this button is now on GPIO_PIN_11. This interrupt is handled by the HAL_GPIO_EXTI_Callback function which i can implement in my main.c file. I am using … WebThe below configuration uses STM HAL library. Initially, you enable the power clock, then you alarm the PVD interrupt and give it a priority. Also you set the level for this interrupt: this is the voltage level at which the interrupt is triggered, in my case I set it to 2.9V. void PVD_Config (void) { /* 1.
