InvIoT - Menu runMenuScreenSaver

menu.runMenuSreenSaver

DESCRIPTION

It works like menu.runMenu(), but if no button is press or the rotary is not moved for few seconds, it calls a screenSaverBegin function, and then it loops in a screenSaverLoop function.

When a button or rotary changes value, it calls screenSaverEnd function to end the screen saver mode.
