DM816x DVR RDK 00.07.00.02 run time read GPIO Input status

I need to read a GPIO input status in run time, anyone know how to do that?

i'm using DM816x DVR RDK board with version 00.07.00.02

I refer to the application source code "app_dio_if.c", i can only set a input sensor to detect falling edge or rising edge. and then wait for the interrupt.

How about if i need to read it in runtime? eg to get GPIO Input 1 is High or Low?

    Hi Ken,

    By reading the GPIO sysfs entries we can know the status of the GPIO pins.

    Go through the GPIO user guide for more details for usage.
