Aim: Read GPIO interrupt read using c code.
I refer to a number of Linux pages and google it.
Follow this specific link which is related to me: https://www.linux.com/training-tutorials/beaglebone-black-how-get-interrupts-through-linux-gpio/#:~:text=The%20header%20pins%20on%20each,I%2FO%20(GPIO).&text=The%20GPIO%20support%20in%20Linux,either%20of%20these%20cases%20occurs.
But I Not solved yet how to call a method at on_event ().
