Using Screens with Raspberry Pi

Raspberry Pi is a fully functional computer residing on a printed circuit board less than four inches long. Designed as an educational tool, it has found widespread favor with hobbyists and professionals alike for a dazzling array of uses.

Screens supports Raspberry Pi’s pre-installed RealVNC virtual network computing server, as long as a couple of configuration settings are respected.

Configure Raspberry Pi’s RealVNC Server

  • On your Raspberry Pi, boot into the desktop. If the desktop isn’t a viable option, start VNC Server from the command line.
  • Navigate to Menu > Preferences > Raspberry Pi Configuration > Interfaces and confirm that VNC is enabled.
  • Open _VNC Server’_s Options window.
  • Under Security, confirm that Authentication is set to VNC Password and that Encryption is set to Prefer On.
  • Under Users & Permissions, confirm that the Standard User is allowed to receive incoming connections and that a password is set for the user account.
  • Double-click the VNC icon on your taskbar to open the VNC Server dialog and make a note of the IP address.

Configure Screens for iOS

  • Launch Screens for iOS.
  • Tap the + button to add a new “screen.”
  • Tap New Screen.
  • If your Raspberry Pi appears in the Nearby & Remote Computers list, select it. Otherwise, tap Custom near the top-right corner of the display.
  • Name your new “screen.”
  • Assign your new “screen” to a Group, if desired.
  • In the Address field, enter the IP address displayed in RealVNC’s dialog earlier.
  • In the Port field, enter the port number configured in RealVNC.
  • In the Operating System field, enter Raspberry Pi.
  • In the Authentication Method field, enter VNC Password.
  • For the Password field, enter the password configured in RealVNC, or select Ask at Connection to authenticate each connection attempt.
  • Complete the rest of the configuration as appropriate for your usage scenario.
