4x1 Mux Behavioral Description

	);

	// Buttons with PULL_MODE=UP read 0 when pressed and 1 when unpressed.
	// Inverting 'btn' converts the active-low button press to logic 1,
	// so pressing the selected button turns the active-high LED ON (1 = ON).

Set up a Chromecast from a Linux PC, without an Android or iOS mobile device and without Google Home

	# Allows you to put your Chromecast on WiFi and do Chromecast initial setup
	# without using the Google Home app at all, just using a normal Linux computer.
	#
	# You do need your Chromecast to be on Ethernet, or (untested) to join its setup WiFi
	# network with your PC, and you also need to find out its IP yourself with e.g.
	# Wireshark.
