I write in lxterminal : sudo stty -F /dev/ttyUS0 460800

Have you got a solution to automatically a connection usb0.
Thanks for your response.

  SOG damping
Posted by: SkipperEarly - 04-19-2017, 02:20 AM - Forum: How do I...? - No Replies

I am using the u-blox GPS dongle and like its sensitivity, however when the speed over ground is calculated in op I get variances between 0,01 - 1,2knots ! even when staying static on land. 

Is there any way to set a damping so that only "real SOG" is send as NMEA or signalK message ?


PS: have in the meantime also found a related threat on the cruisersforum - beta tests and it seems that ocpn has changed SOG calculation in 4.6.1 from earlier versions. This may explain that I didnt notice this behaviour earlier.


  Which Radar might work in the future?
Posted by: YachtShah - 04-18-2017, 06:53 PM - Forum: General discussion - Replies (1)

Hey guys,

I have been reading this blog, and love the work that you are all achieving here.  I will definitely be making up my own system over the next year or two.  Other boat jobs will stop me from achieving this any sooner.

Right now I have a problem with the resident Nav system and wondering what I should be repairing or not.  I am guessing that proprietary analog radars (like my existing Raymarine RD218) will never talk to anything other than their dedicated partner display.

Any ideas which Radar will be supported in future year(s)?  I see that most of the new HD Digital Radar offer Ethernet / Wifi connectivity. 

Already the Garmin HD/xHD are able to be displayed as overlays on OpenCPN - anyone have experience of this?  Is a reliable function or just for playing?  Anyone know of other development for other manufacturers'?

In summary, I am wondering if I should remove the Raymarine system and replace with Garmin, then implement OpenPlotter and OpenCPN as the ultimate tool in a year or two.

Thanks, Andy


  Heel shows in inspector but not in opencpn?
Posted by: svsputnik1 - 04-15-2017, 12:17 PM - Forum: General discussion - Replies (5)

Hey guys

I have the BNO-055 sensor for magnetic and gyroscope.  The thing seems to be working as it is recognized by openplotter (see screenshot).  The data shows in the inspector (although I'm not sure I understand what it means) but if I add it in a dashboard in opencpn, it stays empty, even if I move the breadboard where the sensor is pinned for now.  Any idea of the missing link??

Thanks

  generate NMEA 0183 sentences with private unit
Posted by: CVL - 04-13-2017, 05:36 PM - Forum: How do I...? - Replies (2)

Hello,

I managed to create NMEA-sentences $--MTW from the Signal-K value of a DSB18B20 - but the value in the sentence shows up in Kelvin. Is there any way to have it converted to °C before it's piped to kplex ?
I know that SK works exclusively with SI-Units, and conversion should be done on the client side, but my cockpit instrument won't do any conversion, it will just show the nmea value, so it has to be done before sending it over the wire...

Thanks in advance
Christian


  MPU-9255
Posted by: abarrow - 04-12-2017, 02:17 PM - Forum: General discussion - Replies (36)

Hola!

I've been fiddling with an MPU-9255-based IMU, and using the code on this fork https://github.com/Nick-Currawong/RTIMULib2, I've been able to properly detect and calibrate the unit.

The problem is that if I move the newly compiled code into Openplotter, it fails to start. I'm fairly certain it is due to a check of the .ini setup file for the proper IMU type. In the IMU code that comes with Openplotter, the IMU types go up to "10", while with the new code, the MPU-9255 is type "11". Apparently there is something in the Openplotter start-up code that checks this, as I can change that one item in the .ini file to another value and Openplotter starts properly.

Sailoog, would you have a moment to tell me where in the code this check is happening? I'm happy to modify the code on my own, I just don't know where to look for it.

Thanks, and thanks for spending so much time to create a great system for all of us.


Information New OpenPlotter v0.10.0alpha release
Posted by: Sailoog - 04-12-2017, 12:48 PM - Forum: General discussion - Replies (24)

Hi OP user,

We have published a new image:


http://www.sailoog.com/en/blog/download-...lpha-noobs

The bad news:

Signal K is suffering changes and they are affecting to most features of OpenPlotter. We have already rewrite some of them but others need still work. This is why this last image is still alpha.

The good news:

The main feature of this new image is a self-updating system. You will be able to apply all changes we are doing until you get an stable system without having to burn a new image: https://sailoog.gitbooks.io/openplotter-...ating.html

Thanks to all for your patience.


  [SOLVED] OP boot problem
Posted by: CVL - 04-12-2017, 11:47 AM - Forum: Bug Reports - Replies (16)

Hello

thanks for releasing OP 0.10 which works nice on simple RPi 2. But as soon as I put on the UPS Pico Hat it won't boot anymore. After the colourful first boot screen, it tells

sh: can't  access tty; job control turned off

and drops out to an emergency prompt: /#

dmesg shows nothing suspicious, it stops after initializing USB.

Did you change anything with regard to the "normal" raspian boot sequence ?

The Pico needs to reserve GPIO 22 et 27 - are they used by any other process on OP 0.10 ?

OP 0.8 worked nicely with the Pico but : http://forum.openmarine.net/showthread.php?tid=384

Thanks in advance

After downloading the new V0.10.0 image and updating to v0.10.1 , opencpn won't load the Spanish oeSENC charts I bought from O charts, wrong Userkey comes up.  

Any ideas how to rectify this ?

  YL-40 Analog to Digital converter
Posted by: AquaholicM31 - 04-12-2017, 06:21 AM - Forum: General discussion - Replies (1)

Hi All,

Does anyone know if Openplotter is compatible with the YL-40 analog to digital converter or does it only work with the MCP3008? 
I would use the chip but it just seems a pain to have to wire up the chip rather than using a pi/arduino self contained unit (which i already have).
