I created a simply timer variable but it keeps on saying the variable is not defined but i can not tell why, if someone can help the section of code is below, Thanks.

Code: Select all

def listen_rfid(self):
        global pin
        global accessLogId
        global counter      
        keys = "X^1234567890XXXXqwertzuiopXXXXasdfghjklXXXXXyxcvbnmXXXXXXXXXXXXXXXXXXXXXXX"
        dev = InputDevice('/dev/input/event3')
        rfid_presented = ""
        counter = 0
    while True:
        if counter == 1:
             dev = InputDevice('/dev/input/event2')
        else:
            dev = InputDevice('/dev/input/event3')

Well, at first glance it looks like your indentation is all over the place. Python doesn't like that.

Would also be helpful for you to share a more complete code example and the full error message that you receive. At the moment, we have no idea which variable is the problem.

It may also help to see the output of

Code: Select all

xinput list

If it’s the event lines causing the issue.
