  installing extra nodes
Posted by: JD1 - 09-04-2017, 02:26 AM - Forum: Node Red - Replies (1)

I am just curious if keeping custom nodes  (rather than having to replace them after every upgrade) is part of the roadmap and if so, when approximately we can see that implemented (a month, a year ?). I know it's hard to narrow these things down but it would be very nice to get at least a vague idea when this might happen.


  Observations on OP at sea
Posted by: Littlechay - 09-02-2017, 04:43 PM - Forum: General discussion - Replies (12)

Here are some notes that I have made whilst experiences on my latest trip are still fresh in my mind. 

Openplotter - Version 0.14.3

Sensors - 
IMU - MPU9150
Temp pressure humidity - BME280
Temperature - 1W
GPS Hat with external antenna

AIS and wind data were shared from my boat PC via UDP over Wifi. AIS I used but never used wind data on the plotter as the screen real-estate is too limited. I have a wind instrument, a windex, and wet finger anyway! 

OCPN - impossible to perform some actions on the small RPi touch screen. Edit a waypoint for example as its impossible to get to the OK button. This is an OCPN scree realestate management issue. 

Compass stops working after 8 hours or so. Restarting sensors sometimes works but on many occasions restarting sensors, signal K and NMEA has no effect and the only way to get it running again is to perform a power off reboot (Normal soft reboot doesn't work). No error messages when running OP from the command line. Processor usage usually runs at about 30% but rises to 50% when this occurs. There may or maynot be some interaction with a bug that I reported in OCPN where if auto-follow is active the heading indicator on screen becomes inactive (COG continues to work).

Maybe connected with the above is that sometimes OCPN slows to a crawl or locks up completely and will not shutdown. Unfortunately in versions of OCPN since 3.something the track is not recorded to the drive in realtime resulting in lost tracks in the event of a crash or forced shutdown (for this reason I know of a few people who are still using ancient versions of OCPN). Hence the track recorded on the Pi plotter for this voyage has huge gaps in it. 

Could the above two issues be related to memory allocated to the track etc. filling up? 

Anybody got the official RPi touch screen to actually work as a touch screen.. i.e. at least get right click to work?

Anybody used something like a game controller as a mouse/button pad? I have never found a touch screen that is really usable at sea on any equipment so for me touch screens on boat nav equipment are only for in port use and planning (quite a few 10 of ks of miles at sea testing new stuff for one of the major manufacturers - they understand but touchscreens sell plotters at the boatshows). When things get tough something else is required, preferably a one handed thing. Maybe one of those presentation handsets? Most people that I know that sail in bouncy stuff regularly use a trackball as their pointer input and that is what I use at the nav desk (Logitech M570 being the usual preferred device). However for the cockpit and watchkeeping station under the hard dodger something else is needed. Ideas please?

Has anybody scripted screen brightness controls to buttons yet? As actions perhaps? I'm thinking of adding two buttons with actions to increment/decrement the brightness setting by 10 at each push? I've been using this from a terminal to adjust screen brightness "echo 255 > /sys/class/backlight/rpi_backlight/brightness"; replacing 255 with anything from 25 to 255 as required. 

Anybody got a better way of doing this or perhaps has done something with Node Red (I haven't got my head around this yet any tutorials out there?). The problem with software brightness is that say you have the brightness turned right down at night and are doing a sail change at sunrise. You come back the plotter and can't see anything on screen therefore it is impossible to navigate to software controls. Hardware wins in this case I think.

Has anybody made any graphic devices in NodeRed or similar for a barograph and a TWS/TWD ribbon similar to those in OCPN? They are crippled in real life use by the fact that the history is limited to the last 20 minutes in the case of the wind graph and that the it is impossible to set the y axis in the case of the OCPN barograph. 

So in summary. The combination of my hardware and OP worked fairly well. Some ergonomics need to be addressed; touchscreen and other I/O issue. But Openplotter and OCPN were a great combination.

Stability and lost data when OCPN fails is a major issue. For the whole trip I also ran OCPN and Nobeltec TZ on W10 on my downstairs boat computer neither of which missed a beat so the issues reported are Openplotter/Pi/Linux specific. 

Cheers
Chris


  missing nodes in node red in 0.15.0
Posted by: JD1 - 09-02-2017, 03:47 PM - Forum: Node Red - Replies (2)

When I upgraded to the latest OP I lost a node that did averaging of data. I used that node quite a bit.
I am wondering why it disappeared and if there is some other node that might have that functionality in it (or if I should write a function)


Exclamation Translators needed for beta version
Posted by: Sailoog - 09-02-2017, 07:05 AM - Forum: General discussion - Replies (4)

Hi OP users,

We are close to beta version and we have started translating OP interface into several languages. OP project has been approved by Crowdin platform and they give us full support. thanks!

https://crwd.in/openplotter

You can work right there using useful translation tools and the files will be synchronized with OP code. Create an account in crowdin and join the project, it is really easy. Let us know if you have any problem.

If your language is not supported but you want to translate the interface into it, let us know and we will add it.

Thanks!!!!


  [SOLVED] OpenPlotter 0.14.4 to 0.15 upgrade issues
Posted by: JD1 - 09-01-2017, 06:09 PM - Forum: Bug Reports - Replies (4)

Just tried to do this upgrade. Alas, it doesn't seem to complete properly. It goes through all the motions but after a re-boot it still shows version 0.14.4. openplotter/.openplotter.conf shows the version as 0.15. Node-Red reported finishing during update but signalK update didn't seem to have been done according to the progress screen generated during the upgrade. Huh


  [solved] Battery monitor
Posted by: Luckbert - 09-01-2017, 02:38 PM - Forum: How do I...? - Replies (26)

Hallo zusammen,

Ich möchte die Batteriespannung überwachen. Hauptsächlich sind die ermittelten Werte mit Aktionen zu verknüpfen. Das Design sollte so einfach wie möglich sein. 3 Batterien sollten überwacht werden.

Ich habe etwas gegooglet und folgende Dinge gefunden. Ich hoffe du kannst mit etwas bei der Auswahl der Teile helfen.

  NMEA 0183 generated sentences not persistent over reboot
Posted by: CVL - 08-29-2017, 12:47 PM - Forum: Bug Reports - Replies (10)

Hi everybody

This summer I had OP 0.13 on the boat and tried to feed 1W temperature to MTW-sentence via the NMEA0183- Generator. This worked OK whilst doing the configuration, the MTW sentence showed up in the logs with correct values, but after a reboot it showed -273.1 as a value, which is just the conversion value from °K to °C. Tried to reconfigure several times, but never got correct values after a reboot.

So it seems that the NMA-Generator doesn't get anymore the value from 1W-Sensor after a fresh boot ???

After coming home, I updated to OP 0.14.5, same behaviour. I have to restart configuration all over (1W, SK restart, NMEA configurator, SK restart) to have correct values.
Might be the same issue as http://forum.openmarine.net/showthread.php?tid=706
But as it is present in 0.13 and 0.14.5 it rather seems to me being a problem with data getting from 1W to SK to NMEA Generator.

Thanks for any help
Christian

  Help lost version info

Hi

Help, I seem to have lost the version info so I can no longer do updates. I think its my fault as I was modifying modules file. Should there be a line in there that refer to the version ?

Thanks

  [SOLVED] 0.14.5 can't add signal K keys to MQTT topics

When adding a MQTT topic, I can't edit a signal k key. I wanted to publish the state of an GPIO port.
