DCC-DCC converter

To run the Raspberry PI from the 7.4 Volt Battery of the car the DC-DC converter has to be soldered into the voltage supply chain.

For a start a 3D Printed case for the Raspberry PI was used:

Raspbian

Raspbian Stretch with desktop and recommended software

  1. Download Zip File from https://www.raspberrypi.org/downloads/raspbian/
  2. Create SD Card as described in https://www.raspberrypi.org/documentation/installation/installing-images/
  3. Insert SD Card into Raspberry PI
  4. Connect Keyboard, Mouse, HDMI-Monitor and 5 Volt Mini USB (2.5 Amps recommended)
  5. Setup Country, pi user password etc. and connect to your WIFI network - after the setup you'll be asked to restart your pi

WebCam Interface

cd /usr/local/src
sudo git clone https://github.com/silvanmelchior/RPi_Cam_Web_Interface.git
cd RPi_Cam_Web_Interface/
./install.sh

In case of error

A message like: 

#mmal: mmal_component_create_core: could not create component 'vc.ril.camera' (1)
sh: 1: /var/www/html/macros/error_hard.sh: Permission denied

Indicates that you might have a cabling problem.

In case of success

http://<yourpi>/html should show the cam interface: RpiCamControl2019-06-21.png

Tested on

  1. Mac OS 10.13.6 High Sierra with macports 2.5.4
  2. Ubuntu 18.04.2 LTS

OpenCV

MacOS

If you'd like to generally use OpenCV you can get it e.g. from the macports project: 

sudo port install opencv +java
ls /opt/local/share/OpenCV/java
libopencv_java343.dylib opencv-343.jar

For your convenience you'll find these two files in the lib directory.

Ubuntu 18

You might want to use scripts/opencvubuntu to download the 75 MByte libopencv_java343.so and install the backports libjasper libraries that are not published with Ubuntu 18 by default. You'll find some other links in the script that might also give you hints on how to proceed if you have another environment or different needs. You might want to create an Issue if you run into trouble.

Windows

Help Wanted -please file an issue if you want to things running on Windows.

[edit]

Deploying to your Raspberry is done by compiling e.g. on a laptop and then transferring the results to your PI.

You need to configure your targetHost and targetUser in a file ~/dukes/dukes.ini

Example Configuration

#
# rc-dukes configuration file
# see https://github.com/rc-dukes/dukes
#
targetHost=10.9.8.7
targetUser=pi

The deploy script as a help option that shows how it can be used: 

./deploy.sh -h
deploy.sh [-d|-h|-m|-s]

  -d |--debug             : debug this script
  -m |--maven             : run maven install
  -h |--help              : show this usage
  -s |--start             : deploy and start duke-farm fat jar
  • deploy -m will create the duke-farm fat jar
  • deploy -s will send the jar to your PI using rsync and start it
