RPi.GPIO interrupt not calling function long enough

So I'm trying to design an LCD screen to have a Menu and a bunch of different functions and its supposed to take 4 buttons. A select, a menu, and an up and down. Right now I'm just trying to work on the Menu button. I want it to always display the clock unless the menu button is pressed. But when I press the button it doesn't stay on screen for the 5 seconds it's supposed to. I have no idea why it wont either. I've looked up the RPi interrupt and followed it, but it still won't stay up. The "hi" appears for not even half a second. I'm also using the raspberry pi spy's LCD library which I can link if needed be. The only thing I did was modify some timing things to match those of my displays and added the abilty to add text to any of the four rows at once seeings that I have a 20x4 display. If someone could help me, it would be greatly appreciated.



Here's the code:

PS:The lcd.lcd_init doubles to clear the screen which is why I call it so much.

          Your method clock() which is running in infinite loop, always override text on display with time.



          You must stop clock() method when Menu() function runs.



          I added global variable menu pressed:



          #!usr/bin/python3
          
import RPi.GPIO as GPIO
          
import time
          
import sys
          
sys.path.append('/home/pi/Downloads')
          
import lcd
          

          
GPIO.setwarnings(False)
          
GPIO.setmode(GPIO.BOARD)
          
#GPIO.setup(33, GPIO.IN, pull_up_down=GPIO.PUD_UP)
          
GPIO.setup(11, GPIO.IN, pull_up_down=GPIO.PUD_UP)
          
#GPIO.setup(13, GPIO.IN, pull_up_down=GPIO.PUD_UP)
          
#GPIO.setup(15, GPIO.IN, pull_up_down=GPIO.PUD_UP)

          • So, now it does stay on the screen for the 5 seconds its supposed to but, now it calls it twice before going back to the clock. And I tried to figure it out but I dont have any clue why

          • Does it run twice everytime? Did you try to increase bounce time? I have no other idea.

          • So, now it does stay on the screen for the 5 seconds its supposed to but, now it calls it twice before going back to the clock. And I tried to figure it out but I dont have any clue why

          Your method clock() which is running in infinite loop, always override text on display with time.



          You must stop clock() method when Menu() function runs.



          I added global variable menu pressed:

          • So, now it does stay on the screen for the 5 seconds its supposed to but, now it calls it twice before going back to the clock. And I tried to figure it out but I dont have any clue why

          • Does it run twice everytime? Did you try to increase bounce time? I have no other idea.
