	# Start the rf24 listener script as a service at startup
	# Copy this file into /etc/systemd/system as root, for example:
	# sudo cp myscript.service /etc/systemd/system/rf24_receiver.service
	# Once this has been copied, you can attempt to start the service using the following command:
	# sudo systemctl start rf24_receiver.service
	# Stop it using following command:

Peter's User_Setup.h file from ESP32 Unleashed

	// Course location: https://techexplorations.com/so/esp32uev/
	// USER DEFINED SETTINGS
	// Set driver type, fonts to be loaded, pins used and SPI control method etc
	//
	// See the User_Setup_Select.h file if you wish to be able to define multiple
	// setups and then easily select which setup file is used by the compiler.
	//
	// If this file is edited correctly then all the library example sketches should
	// run without the need to make any more changes for a particular hardware setup!
	// Note that some sketches are designed for a particular TFT pixel width/height
