I read about this macro in the docs. It is used to avoid compiler warnings on unused objects in this case. In the example on page 115 of this tutorial about LVGL, it is used with “toggle_switch” as an argument, but this object is used in the very next line of code, which leads me to think that I have not understood well the purpose of this LV_UNUSED() macro. Would you please clarify it? Thanks

Hi.
You’re right about your assumption.
I think that is not needed in that case because those variables are being used.
I think we may have copied it throughout all our examples, when we started our code based on some library examples.
