There's two applications,
A prepares to use a GPIO pin then starts doing its tasks.
After a while,
B is also launched and prepares to use the same GPIO pin by
A. A warning pops up, but this is only a warning.
RuntimeWarning: This channel is already in use, continuing anyway. Use GPIO.setwarnings(False) to disable warnings.
B also toggle the same GPIO pin, potentially damaging
A's work? What options do I have to prevent this?
I would love to set up an experiment, but all my Pis are currently in use.
