Hi, i have been playing with many RPI so far but right now i have a beginner question:
Why is this warning issued when i try to use the GPIO 8?
>>> gpio.setup(8, gpio.OUT);
__main__:1: RuntimeWarning: This channel is already in use, continuing anyway. Use GPIO.setwarnings(False) to disable warnings.
Now i know that it might have to do with it being an UART / Serial pin. But i have disabled it with raspi-config > advanced > Disable serial
Apart from the warning, everything seems to work OK, so should i worry about it?
