Appendix E The Raspberry Pi Configuration Tool 237THE OFFICIAL RASPBERRY PI BEGINNER’S GUIDE
n VNC: Enables or disables the Virtual Network Computing (VNC) interface, which allows you to
view the graphical desktop on the Pi from another computer on your network using a VNC client.
n SPI: Enables or disables the Serial Peripheral Interface (SPI), used to control some
hardware add-ons which connect to the GPIO pins.
n I2C: Enables or disables the Inter-Integrated Circuit (I²C) interface, used to control some
hardware add-ons which connect to the GPIO pins.
n Serial Port: Enables or disables the Raspberry Pi’s serial port, available on the GPIO pins.
n Serial Console: Enables or disables the serial console, a command-line interface available
on the serial port. This option is only available if the Serial Port setting above is set to Enabled.
n 1-Wire: Enables or disables the 1-Wire interface, used to control some hardware add-ons
which connect to the GPIO pins.
n Remote GPIO: Enables or disables a network service which allows you to control the
Raspberry Pi’s GPIO pins from another computer on your network using the GPIO Zero library.
More information on remote GPIO is available from gpiozero.readthedocs.io.
Performance tab
The Performance tab holds settings which control how much memory is available and how
fast the Raspberry Pi processor runs.
