  PyPilot or OpenPlotter?
Posted by: KipHansen - 18 minutes ago - Forum: General discussion - No Replies

I am replacing an ancient Robertson AP200DL complete with motor controller and a steering drive 12VDC motor.

My question is:

Is it one  or the other?  

     PyPilot running on a TinyPilot hat or /box from Sean  
     OR 
     PyPilot running in OpenPlotter on a dedicated Raspberry Pi 4 (or 3+) setup?

Either of these can run a PyPilot motor controller, right?

Obviously, OpenPlotter has a lot more functionality, but both can do basic autopilot and steer a set heading, right?


  RaspAp WiFi Hotspot Webbased
Posted by: jamos.tan@gmail.com - Today, 02:56 AM - Forum: General discussion - Replies (1)

Anybody heard of this nice piece of software before?
Just installed it, it's great. It has more capabilities of the network tab in openplotter, however entirely web based.
It monitors hotspot connection usage, has openvpn and lot's of other nice features. You can even reboot your raspberry from the web-interface. 
It basically turns your Pi into a router. The main IP of your Pi broadcasts a light weight, but very nicely styled web app in which you can login just like a router. You don't have to fill in a port, just the IP.

One piece of advice, if you don't use ethernet and are on a headless system, be sure to follow the installation manual carefully. You need to check the 'Wifi client AP mode' in the advanced hotspot settings.

They offer a quick installer, very easy. Have it running stable a few days now. I feel it might be worth trying for others as well and that it even potentially can replace all network managers currently in OP. Maybe integrate it ieven in the Noobs image in the future just like Grafana, etc.


 All of you willing to try, here's the Github reporitory:  https://github.com/billz/raspap-webgui

Tested on a 3B+ on stretch and a Pi4 on debian.


  Simple 3G device for remote monitoring
Posted by: affinite - Yesterday, 12:15 PM - Forum: General discussion - Replies (1)

Hi Can anyone recommend a simple, unlocked 3G data device that I can use for remote monitoring of OP over the internet.
(Boat in Greece, me in UK)
I don't really need it for internet access internet whilst on-board but I want a low power/low running cost device that I can leave connected when away from the boat so that I can continue to monitor boat systems etc using NodeRed/MQTT
I could try marina WiFi but that is notoriously unreliable so 3G seems best for this purpose.
I have an old Vodafone data dongle but not sure how to set it up on Rasp Pi

Thanks


  Chaging theme to dark colors and I can't see stuff in OpenPlotter
Posted by: mgrouch - 03-30-2020, 11:58 PM - Forum: Bug Reports - Replies (4)

There are seems places in OpenPlotter programs where colors are hard coded.
There is yellow for row selection and there is while fond color in OpenPlotter module install.

When I switched my desktop theme to dark colors (White fond on dark menus)
everything is fine in Raspberry Pi UI (OpenBox, etc)

but in those two places in OpenPlotter set of programs I can't see anything.
It becomes white on yellow or white on white.

The colors everywhere should come from the UI theme.
Unless application manages all colors by itself.

Thanks,
--MG


  There are other char plotters for Openplotter
Posted by: mgrouch - 03-29-2020, 06:11 PM - Forum: General discussion - Replies (1)

I've found two other ChartPlotter programs (apart from OpenCPN) which can run on Openplotter
(or raspbian Buster pi).


The first one is called AvNav

Installation instructions here:

https://bareboat-necessities.github.io/m...at/#_avnav

The second one is QtVlm

Installation instructions here:

https://bareboat-necessities.github.io/m...at/#_qtvlm

Both of them support various char formats, mbtiles, etc.

It would be nice to have an option to install them too in next version on OpenPlotter

Thanks,
--MG


Photo NECO clutch connection
Posted by: mlvg - 03-29-2020, 03:49 PM - Forum: General discussion - Replies (2)

Just got a Tinypilot and a motor controller from Sean, works great (testing on my desk).
One question: what is the best way to connect the NECO clutch (relay) in such a way that it is activated with the Tinypilot AP switch?
Thanks, Matthieu


  Interfacing an old autohelm 1000 seatalk

Hello every body.
I am buiding an oppen plotter system to offer some new teck to my old dufour 27.
I also own an old autohelm 1000
I was wondering if it is possible to drive the autohelm 1000 with the seatalk interface or if i need to modify the hardware to drive the motor directely with a motor drive to use pypilot.

  RS485 USB - SignalK NMEA Serial input log
Posted by: jamos.tan@gmail.com - 03-29-2020, 08:09 AM - Forum: General discussion - Replies (6)

Hi,

I have connected a depth sounder to an RS485 USB dongle to the Raspberry pi.
It works when I check with this command:

Code:
sudo screen /dev/ttyUSB2 4800

Sudo cat is also fine by the way. It only works with baudrate 4800 by the way.

It outputs this:


Code:
pi@openplotter:~ $ sudo cat /dev/ttyUSB2
SDDPT,,*57
$SDDBT,,f,,M,,F*28
$SDDPT,,*57
$SDDBT,,f,,M,,F*28
$SDDPT,,*57
$SDDBT,,f,,M,,F*28
$SDDPT,,*57
$SDDBT,,f,,M,,F*28
$SDDPT,,*57
$SDDBT,,f,,M,,F*28
$SDDPT,,*57
$SDDBT,,f,,M,,F*28
$SDDPT,,*57
$SDDBT,,f,,M,,F*28
$SDDPT,,*57
$SDDBT,,f,,M,,F*28

I have tried assigning the serial port within OP to Kplex as an input.
I also tried the other way, manually add a serial connection in SignalK for port /dev/ttyUSB2 with the correct baudrate: 4800
In addition to this I've set the SignalK NMEA converter plugin to check the depth sentences.

However, there is no SignalK sentence being generated, and no value for the depth.
The log for the connection says this:


Code:
Mar 29 11:51:51 false
Mar 29 11:51:51 initing!
Mar 29 11:51:51 nmea0183
Mar 29 11:51:51 Error: Device or resource busy, cannot open /dev/ttyUSB2


It only has the "cannot open" error when I check the "checksum logging" for the connection.
I have de-assigned the serial in OP to none, so I know the port is not being used by any other process.

Anybody have any idea how i can get the depth sounder to work? I feel I am getting close.

Kind regards,

Jamos


  2020-03-24-OpenPlotter-v2-Headless-img: no wifi access point
Posted by: Eleon - 03-29-2020, 05:07 AM - Forum: Bug Reports - Replies (5)

Hi,

the 2020-03-24-OpenPlotter-v2-Headless-img image doesn't seem to open a wifi access point. I have a brand new Pi 4 + brand new SD card that this was tested on. Unfortunately I don't have a suitable display cable and was relying on remote connection to connect to the Pi. After flashing the SD card and starting the Pi, everything seems fine, but the Openplotter wifi network doesn't appear.

I then tried a standard Raspian version to test everything and got a remote connection working with these instructions: https://hackernoon.com/raspberry-pi-head...2ccabd75d0

Finally I tested the Noobs version (2020-03-24-OpenPlotter-v2-Headless-NOOBS) and that seems fine. About 10 minutes after starting the Openplotter network appeared.

Can it be that the headless-img is simply missing the config to setup the wifi access point?


  SignalK - InfluxDB - Grafana - how to display customized units
Posted by: SkipperEarly - 03-28-2020, 05:55 AM - Forum: How do I...? - Replies (3)

I understand that units used in SignalK are standardized, which means e.g. temperature is in Kelvin.

My brain however just works in Celsius and I have therefore set in the OP diagnose SiglakK the privat units from K>C. Converted values are sent correctly in NMEA strings to Ocpn.

I now would like to store historic values in InfluxDB and display them with Grafana - which was recommended by some other users. Have managed to configure the grafana dashboard but struggle to get the units for temperature and pressure converted to my preferred units. 

Do I miss some setting in either of the tools?
Has anyone solved this little problem without programming or scripting?
