openPlotter

Setup Pi:

• upgrade to openPlotter 0.17.0 beta
• Preferences > Raspberry Configuration > Interfaces > SSH:enable (Remote-access via WinSCP and Putty)
• sudo apt-get install tightvncserver (make RDP working)
• sudo apt-get install can-utils
• sudo apt-get install mc

Setup Android:

• RDC from playStore (working)
• aRDP free from playStore (suits my needs best)

Setup piCAN2:

  • http://forum.openmarine.net/showthread.php?tid=92&page=2
  • https://www.dropbox.com/sh/88dxdzrbea7jlhv/AAD_Q8XRdB3bRrRbPQRrbST-a?dl=0 (all changes to file-system, NOT uptodate)

• add to /boot/config.txt

dtparam=spi=on
dtoverlay=mcp2515-can0,oscillator=16000000,interrupt=25
dtoverlay=spi-bcm2835-overlay

• add to /etc/network/interfaces (overwritten by /home/pi/.config/openplotter/wifi_server.py!)

#physical can interfaces
allow-hotplug can0
iface can0 can static
bitrate 250000
down /sbin/ip link set $IFACE down
up /sbin/ifconfig $IFACE txqueuelen 10000

• install canboat

mkdir ~/canboat
cd ~/canboat
sudo apt-get install xsltproc
git clone git://github.com/canboat/canboat
cd canboat
sudo make
sudo make install

sudo apt-get install libconfig-general-perl

• copy and edit /home/pi/canboat/canboat/config/n2kd to /etc/default/n2kd (is this really needed?)

• add to /home/pi/.config/openplotter/OP-signalk/openplotter-settings.json (OP ver 0.10.0)
• add to /home/pi/.openplotter/openplotter-settings.json (OP ver 0.17.0)

configure kplex and signalk

• 'Signal K Server Plugin Configuration' > activate 'Convert Signal K to NMEA0183'
  • select sentences you are interested in
• NMEA0183 (this is kplex) > Advanced >
  • add input channel tcp:localhost:10110
  • remove filter at opencpn out channel

[tcp]
name=signalk_in
direction=in
address=localhost
port=10110

[tcp]
name=opencpn
direction=out
mode=server
port=10109
