WebSep 30, 2015 · Don't re-sample your button with GPIO_ReadInputDataBit in your Exti interrupt handler. The very fact that the interrupt handler fired means that there was a rising edge on the GPIO line. All you're doing is making it possible to ignore the button if it was released quickly enough. – Andy Brown.
