STM32 rising and falling button interrupt detection

WebIf using the touchscreen, be sure to configure the GPIO pin as external interrupt (EXTI) with rising/falling edge trigger detection (i.e. GPIO_InitStruct.Mode = GPIO_MODE_IT_RISING_FALLING). Be sure to enable interrupts (NVIC) and generate interrupt handlers for SPI, DMA, and your touchscreen IRQ (if used). WebClick the GPIO pin on the chip view and select the signal GPIO_EXTI. Go to the configuration tab, click the NVIC button and enable the interrupts for EXTI lines. Best regards.
