I was working with a very simple code:
import RPi.GPIO as GPIO
GPIO.setmode(GPIO.BCM)
GPIO.setup(24,GPIO.OUT)
GPIO.output(24,GPIO.HIGH)
But after running one time when I am running the code next time the Thonny IDE is showing me
RuntimeWarning: This channel is already in use, continuing anyway. Use GPIO.setwarnings(False) to disable warnings.
GPIO.setup(24,GPIO.OUT)
Why is this happening?
The GPIO is still working, it's the software refusing to continue without a warning unless you correct the condition causing the warning.
Either do what the warning message says or add the following line at the (logical) end of your script.
GPIO.cleanup()
