I have an issue with events detection in my OrangePi One Plus . I'm running this script as a root user:

import orangepi.oneplus
import OPi.GPIO as GPIO
from time import sleep

channel = 21

GPIO.setmode(orangepi.oneplus.BOARD)
GPIO.setup(channel, GPIO.IN, pull_up_down=GPIO.PUD_UP)

def my_callback(channel):
    print('This is a edge event callback function!')
    print('Edge detected on channel %s'%channel)
    print('This is run in a different thread to your main program')

GPIO.add_event_detect(channel, GPIO.RISING, callback=my_callback)

while True:    
    sleep(.5)

GPIO.cleanup()
print("Bye")

The output is:

inputsInterruptions.py:8: UserWarning: Pull up/down setting are not (yet) fully supported, continuing anyway. Use GPIO.setwarnings(False) to disable warnings.
  GPIO.setup(channel, GPIO.IN, pull_up_down=GPIO.PUD_UP)
inputsInterruptions.py:8: UserWarning: Channel 21 is already in use, continuing anyway. Use GPIO.setwarnings(False) to disable warnings.
  GPIO.setup(channel, GPIO.IN, pull_up_down=GPIO.PUD_UP)

what i'm doing wrong?

Actually I have success with inputs polling method and controlling outputs.

Thank you in advance!!!

Try run as root, this library uses sysfs which can sometimes create permission issues, if you need to run this as a non root user you can great an access group and add the sysfs folder that is denying you access to it i.e '/sys/class/gpio/gpio67/edge'.

In your case if you gave yourself access to the '/sys/class/gpio/gpio67/' folder that should give you access to all the function files within it.
