I wrote some python to blink a led. Without the GPIO.cleanup method, I had the following warning: "This channel is already in use, continuing anyway". Then I did
tempo=1 import RPi.GPIO as GPIO import time try: GPIO.setmode(GPIO.BOARD) GPIO.setup(12,GPIO.OUT) def acende(led): GPIO.output(led,1) return def apaga(led): GPIO.output(led,0) return while(1): acende(12) time.sleep(tempo) apaga(12) time.sleep(tempo) except KeyboardInterrupt: print ("teclado") except: print ("erro") finally: GPIO.cleanup()
But I still got the same warning. How to completely erase my former GPIO settings ?
