  revision notes
Posted by: JD1 - 06-20-2017, 10:08 PM - Forum: General discussion - Replies (2)

Any chance we can get some revision notes when a new version is released? I just installed 0.11.10 but have no clue how it differs from 0.11.9. Even just a few bullet points on the highlights of changes would be wonderful.

BTW, THANKS for all your hard work !!!!


  GPS USB dongle recommendation
Posted by: fbraad - 06-20-2017, 09:31 AM - Forum: General discussion - No Replies

Hi,

My old GPS died so i'm looking for a new GPS USB dongle for use with OpenPlotter. Preferably one with an option to attach an external antenna.
Is there anything i should be aware of in terms of support in openplotter, and do you guys have any product recommendations? I would have bought via the sailoog shop, but it seems to be out of stock.

Thanks
Frederik


  SOLVED How do I extend the SDCard partition size
Posted by: affinite - 06-19-2017, 02:39 PM - Forum: How do I...? - Replies (4)

I seem to have outgrown my 8GB SDCard (charts are on the SD card as this seems faster than on separate USB stick) so I want to move onto a 32GB.
I have created an image of my OP system using Win32 DiskImager but when I restore the image to my 32GB card it only creates an 8GB partition (as per the original) so how can I resize the SD card to 32 GB ?
Thanks Steve


  OpenPlotter and autopilots
Posted by: JD1 - 06-12-2017, 07:29 PM - Forum: General discussion - Replies (10)

I am having some troubles wrapping my mind around all things auto pilot.

What I would like to understand is how to duplicate the +/- 10 degree and +/- 1 degree functionality of the control buttons that are on my Raymarine ST4000+.
It would seem to me that all I need to do is to send some kind of a NMEA 0183 sentence to the E80 display that would then translate the sentence onto it's attached Seatalk bus which then reaches the autopilot and magic happens.
At this point I need a hint as to either what the magic NMEA sentence(s) is/are or a pointer to a URL where I might find documentation that could lead me to that magic sentence.
Somewhat related, currently my AIS feeds data via NMEA 0183 to the E80 chart plotter. I will need to feed that data into openPlotter and from there it needs to go back out to the chartplotter via it's NMEA 0183 input. I can then add the magic autopilot sentences to the stream and presto .... I hope. Has anyone written up how to combine the two streams (AIS and autopilot) ? It would be great if I could find something that shows me how to go about doing this.


  OP 0.11 ?
Posted by: svsputnik1 - 06-12-2017, 03:12 PM - Forum: How do I...? - Replies (5)

Hey guys

I was wondering what is the last version?  I've seen people commenting on OP 0.10 but on github, I see commit on the branch 0.11 ?  Anyway, how can I access the latest version and stay up to date with the releases?

Thanks

  Help: MWV to VWR, Raymarine...
Posted by: jswalwell - 06-10-2017, 12:29 PM - Forum: How do I...? - Replies (7)

Trying to interface an openplotter setup to an older Raymarine ST6000/300 autopilot.

I would have thought that the MWV sentence from my CV7 ultrasonic wind sensor could be converted from available data to VWR for this ancient and unfriendly autopilot that only accepts VWR.  I have set an output to send VWR, but no VWR sentence is being generated on the output.  I can send MWV on the output as well as other sentences.  Any advice appreciated.  Also, if anyone can recommend a seatalk1 to nmea bridge, or method to do so, I am all ears.

I am using the v0.10.0alpha image.  The v0.8.0 image off of the sailoog website (directs to Mega download) cannot output anything.  Please let me know if there is a stable functional non-alpha image that I should download from somewhere else.


  Android tablet as source of nmea gps data
Posted by: PaddyB - 06-10-2017, 08:03 AM - Forum: General discussion - No Replies

Did you know you can run node-red on an  android?
https://nodered.org/docs/platforms/android

Just been playing around and almost got it to act as a source of nmea GPS data for openplotter sent over wifi.

Shame it doesn't actually work ;Wink but pretty sure that because the nmea message is badly created in node-red by me. 

Interesting though Cool

  USB Manager : DVB-T dongle (AIS) not detected
Posted by: ITgroovy - 06-08-2017, 07:55 AM - Forum: How do I...? - Replies (11)

Hello,

Im using OP 0.8.0 on a Raspberry pi 3 with a USB GPS.

I want plug a DVB-T dongle. it seems working good but i cant manage it via USB Manager.

And i didn't find the Tool menu to start the tty auto setup (like said in documentation).

Here you can find my toubleshooting file which contains some screenshots of "ls /dev/tty*" ; "lsusb" ; "dmseg" :
troubleshooting file
So i would understand why i can't manage this USB DVB-T.

Thanks


  Using MCP3008 10 bit Analog to Digital converter
Posted by: olewsaa - 06-07-2017, 03:11 PM - Forum: Feature Requests - Replies (2)

I have experimented a little using the MCP3008 to read current from a smaller and simpler Hall effect current sensor. For some application 10 bit is enough and the MCP3008 has 8 single ended channels and 4 if used differential. Differential measurements makes more sense for these type of current sensors. 

The MCP3008 can also be used for voltage measurements and for this type a single ended measurement is quite ok, it also provide twice as many channels. 

The current measurement is documented at my project pages :  
https://sites.google.com/site/olewsaa/ya...all-sensor

Please feel free to include any of this content in the Openplotter pages. Some day I'll try to find time and energy to include the MCP3008 in the Openplotter code in a similar way as ADS1115 in differential mode, including some contribution to the Openplotter documentation.



Regards,
Ole
