Raspberry Pi User Guide

Setting up the system

Required hardware

  • Raspberry Pi The system was tested on Raspberry Pi3 Model B V1.2 and Raspberry Pi 4. It can work on other models that have a CSI camera interface input.
  • Raspberry Pi 5V power supply
  • Interposer 5V power supply
  • To run the system in standalone mode, besides the accessories that are provided in the AD-FXTOF1-EBZ box you'll need an additional HDMI cable to connect to a monitor and a USB keyboard and mouse
  • RPi camera cable for connection between RPi and AD-FXTOF1-EBZ interposer

Power on sequence

  • Plug the SD card into the Raspberry Pi SD card slot. To benefit from the most recent software updates it is highly recommended to update the SD card with the latest SD card image
  • Connect the HDMI cable from the monitor to the Raspberry Pi HDMI connector
  • Connect the 25 pins flex cable between the camera and the interposer
  • Connect the 15 pins camera cable between the RPi and the P1 connector of the interposer. Make sure to use the cable with contacts on opposite sides.
  • Connect the interposer to the power supply
  • Connect the RPi to the power supply
  • Connect a USB mouse and keyboard to the Raspberry Pi. It's possible to use either a mouse & keyboard combo or a separate mouse and keyboard

Power off sequence

  • Open a terminal and type sudo poweroff. This will safely power off the Raspberry Pi and ensure that the SD card is properly unmounted
  • remove the 5V supply from the Raspberry Pi
  • remove the 5V supply from the interposer

Troubleshooting

  • Linux does not boot
    • The SD card is corrupted and this prevents the system from booting. Reflash the SD card with the SD card image.

Running the evaluation application

Once Linux boots you'll see on the HDMI monitor the Linux desktop and on the top left corner a shortcut to the evaluation application. Double clicking on the icon will start the evaluation application. A console window will open to show the application's status and, after a few seconds, the evaluation application GUI will be displayed.

Enabling the point cloud display in aditof-demo

  • The demo application has the capability to display a point cloud image if it detects an OpenCV module called viz.

Unfortunately OpenCV does not provide binaries for this module so a manual build is needed. The steps required to install OpenCV and include it in the project are presented here: Enable Point Cloud Aditof-Demo

  • If aditof-demo finds all the OpenCV required modules a button in the interface will allow you to display the point cloud. By toggling the button a separate window will appear.
