Tool/software: Linux
Hello All,
I'm working on our custom board, able to configure few gpio's as gpio_keys.
I have configured as below:
USER1 {
label = "UP";
linux,code = <KEY_UP>;
gpios = <&gpio3 7 GPIO_ACTIVE_LOW>;
};
Able to test with evtest command the interrupt,
Event: time 1520873640.120477, type 1 (EV_KEY), code 103 (KEY_UP), value 1
Event: time 1520873640.120477, -------------- SYN_REPORT ------------
Event: time 1520873640.286905, type 1 (EV_KEY), code 103 (KEY_UP), value 0
Event: time 1520873640.286905, -------------- SYN_REPORT ------------
I'm getting event for both rising and falling egde.
but i have below doubts on this:
1. How do i configure only for falling edge ?
2. I need to set an particular functionality for the key pressed, how can i do that? Do i need to wrrite an ISR for this interrupt event?
Thanks
