Assembly

  • On the back of the screen you’ll find four bols, take them off and replace each of them by the coppercolored spacers.
  • Grab the plexiglassplate that came with the screen. This plate will be used to mount the marboard and the Raspberry Pi. We will start with four bolts and four couplers. On the plate you’ll need to use the pre-drilled holes for the Raspberry Pi.The marsboard that came with the WaveShare monitor
    • For this use the bolts with a threaded head (these bolts will take another bolt).
    • The nuts should be on the clear side of the plate (the side with the numbers on) wheras the bolts should be on the side covered with paper.
  • Now grab the marsboard, four nuts, four plastic spacers and four bolts that came with the screen
    • Insert the bolts through the plate so that the head is on the paper side.
    • Put the plastic washers over the thread.
    • Allign the marsboard over the threads, and lower it onto the washers. Make sure the connectors face outwards.
    • Fasten the nuts.
  • The screen and marsboard will communicate with eachother through  a ribbon cable (The paperthin cable that came with your screen).
    • This cable has two sides, the pins needed to transmit signals are bare wheras the other side has a blue cover.
    • Flip the black bar on your screen that says ‘RGB’. RGB connector
    • Flip the black bar on your screen that says ‘RGB’.
    • The two bars should be pointing upwards.
    • Insert the datacable with the bare pins facing the RGB connector of the marsboard, then lower the black bar to secure the connection. Make sure to insert the datacable far enough and symmetrical.
    • Do the same for the RGB-connector on the screen.
  • Test!
    • Apply power to the marsboard. Be sure to use 12V and at least 1A. If your screen does not light up, it means that your connection is faulty.
  • If your screen lit up; use the buttons on the side to select the appropriate source. In our case the source should be HDMI.
    • You can now disconnect the powersupply from the marsboard.
  • Screw the plexiglassplate onto the screen.
  • Get your Raspberry Pi and remove the MicroSD-card. We’ll need to set the screen resolution first.
    • Insert the Micro-SD-card into your computer.
    • Open the config.txt-file.
    • First we need to undo the changes we made to this file in an earlier phase.
      • Look for the line that says: disable overscan = 1
      • Put a '#' in front of it so that it reads: #disable overscan = 1
    • Now we can configure the Pi to work with the WaveShare-touchscreen. For this write the following at the bottom of the config.txt-file (Some manufacturers provide a driver or have other specifications that need to be written down in the config.txt-file. If this is the case for you, you should adhere to those.)
      max_usb_current=1
      hdmi_group=2
      hdmi_mode=1
      hdmi_mode=87
      hdmi_cvt 1280 600 60 6 0 0 0
    • Save the config.txt-file and insert it back into the Raspberry Pi.
  • Get the USBto-Micro-USB cable that came with the screen. Insert the Micro-USB into the Marsboard and insert the full-USB connector into one of the four USB-ports of your Raspberry Pi3B.
  • Get the HDMI cable that came with the screen. Connect it to the HDMIport of the Marsboard and the HDMI-port of your Raspberry Pi. Micro USB and HDMI cables are attached
  • Test if everything works.
    • First power on the screen and make sure that it lits up and has HDMI set as its source.
    • If that’s the case, power on the Raspberry Pi.
    • Your Pi should now boot straight into the public account, and launch the GUI-interface. Test if your touch-screen is responding, if not, recheck the USB-to-Micro-USB cable and go over the config.txt-file once more just to be sure.
    • Get four bolts to screw the Raspberry Pi to the back of your plexiglassplate.
    • You’re now done, connect the peripherals (keyboard, mouse) to your Pi and this machine can now be integrated (i.e. in a cabinet or wall).
