Hi!
I´m still relatively new to phyton so there could be an easy answer to this question.
I´m making my first project that is (at least for me) a bit larger on my PI.
what i´m trying to do is import a module from where i check if a button is pushed into my "master"-module where i collect a bunch of results from different modules in i while loop to have it running 24/7.
when i import the module that has the button-code i get a
gpiozero.exc.GPIOPinInUse: pin 27 is already in use by <gpiozero.Button object on pin GPIO27, pull_up=True, is_active=False>
as soon as python executesThe simple way would be to move the outside the while-loop but as the module is imported to another module´s while loop i don´t se how this can be done.
Does anyone have any ideas?
I don´t know if the code would be of use but here it is:
The module where the button is handeled (GPIO_Door_And_Relays) (the relay-part is still to come):
The "Master"-module code (the parts that has something to do with the issue:
As i normally code in IEC 61131-3 (languages for PLC-programming) so i feel like I´m trying to learn how to walk different, doing something you know but just a bit off all the time.
Any ideas is welcome. As there will be alot more in the GPIO_Door_And_Relays-modules i don´t see it as a option to move everythong into the master-module unless its the last restort.
Best,
Martin
