Preparing your Raspberry Pi for TouchPad and NumPad

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.

Step 2: Setting up TouchPad/NumPad

  • Launch TouchPad or NumPad on your iOS device if it's not already running.

  • You will be prompted you to select a server. Tap 'Yes'.

  • You can also access the Computers List by tapping on the Settings Button:

  • Tap on the Computer you want to connect to.

    Note: If your computer is not listed tap the + Add New Device button to create a new computer manually.

  • If the selected computer was already configured, TouchPad/NumPad will initiate a connection or it will display the Computer settings.

  • Make sure the Operating System is set to Linux.

  • Fill out the required Authentication information.

    • Method: VNC Password,
    • Password: The password you previously created in Step 1.
  • Tap Save and re-select the computer you've just configured.

  • If everything is in order, you should now be connected and ready to connect!
