WebMar 14, 2024 · 3. Unfortunately it is not possible to tell which edge has been detected. If your signal changes slow enough, you could use the actual level of the pin to determine the edge (If IDR & Pin is true, the last edge was a rising one :) ) Or you could use two pins. One to detect rising and one for the falling edges. WebApr 5, 2024 · A GPIO pin can trigger an interrupt when its value changes: either from low-to-high or high-to-low.
