• connector pins 2 and 4 for 5v power for relays.
• connector pin 6 for ground
• connector pin 22 (wiring pi pin 6) turntable
• connector pin 24 (wirint pi pin 10) for camera 1 (top)
• connector pin 26 (wirint pi pin 11) for camera 2 (top-middle)
• connector pin 28 (wirint pi pin 31) for camera 3 (bottom-middle)
• connector pin 32 (wirint pi pin 26) for camera 4 (bottom)
• 4 port USB hub with cameras connected should be plugged into the bottom right of the 4 usb ports on the device
• Bluetooth Keyboard paired
• USB mouse (unless BT keyboard is Mouse/Keyboard combo)

• pip install virtual env
• python3 -m venv ~/Venvs/qc

• sudo apt-get install python3-pyqt5
  • Otherwise you'll have to build it and sip which will be a pain on a Pi

• First activate the Venv

  $ source ~/Venvs/qc/bin/activate
  

• pip install wiringpi

• pip install pycryptodome

• cp -r /usr/lib/python3/dist-packages/PyQt5 Venvs/qc/lib/python3.5/site-packages/PyQt5
• cp /usr/lib/python3/dist-packages/sip.cpython-*.so ~/Venvs/qc/lib/python3.5/site-packages

is not great for this with python but I found the source code here and there is a way to play with it and see what calls you need to make

• Install gphoto2

  $ sudo apt-get install gphoto2
  

  That will give you command line interface.
• Then we want it for python too. Get the dev package so we can build it ourselves

  sudo apt-get install libgphoto2-dev
  

• install the python wrapper - This takes a while (do it in the venv)

  pip install -v gphoto2
  

• if we want to access images we need pillow installed

  pip install pillow
  

• There is an annoyance with the gvfs Gnome file system that will auto mount the camera when connected. This is a prblem because then gphoto2, in some firmware versions, will not be able to claim the device
  • To prevent this you must update the file system explorer Add the following to ~/.config/pcmanfm/LXDE-pi/pcmanfm.conf

  [volume]
  mount_on_startup=0
  mount_removable=0
  

• pip install qdarkstyle

• Running the program

  • First enable the virtual environment.

  $ source ~/Venvs/qc/bin/activate
  

  • Run the program from within the directory

  $ python3 wayscan.py
  

• install QtCreator
  • download from https://www.qt.io/download-qt-installer?hsCtaTracking=9f6a2170-a938-42df-a8e2-a9f0b1d6cdce%7C6cb0de4f-9bb5-4778-ab02-bfb62735f3e5

• https://www.raspberrypi.org/documentation/configuration/wireless/access-point.md

• use obexpushd, need to update /etc/systemd/system/dbus-org.bluez.service

• sudo apt-get install at-spi2-core
