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 errror

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

Servo Interface - Servoblaster

wf@pibee:~ $ cd /usr/local/src
wf@pibee:/usr/local/src $ sudo git clone https://github.com/srcshelton/servoblaster
cd servoblaster
sudo make install
sudo reboot

OpenJDK

sudo apt-get install openjdk-8-jdk

Screen

sudo apt-get install screen
[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
