Hello! I was practicing with the “GPIO DEMO” package In order to test it to implement it in the “Scheduled Player” package. But I have the following problems

1.When using the default setting “gpio 18” the package works correctly, the screen turns from red to green when I send a pulse

1. When configuring the pin with some other “gpio 2”, “gpio 3”. It doesn’t work for me anymore. It only works if I reassign gpio pin 18 in the configuration

And if I try to use the GPIOs in the “scheduled player” package it doesn’t recognize them either. What could be the problem?
