Forward I2C signals to server K and OpenCPN

[PaddyB]

Hi,

I did attach some questions to old threads on similar subjects but thought best to start new thread

I have a RPi3 with Sense hat (I already have it and will distance from RPi via a ribbon cable, to be kept down below and use VNC to Android tablet / phones)

I have the I2C signals in Openplotter - I can see them in 'Inspect'

But I have no idea how to get them to OpenCPN (I add them to Dash but empty) and server K

Do I have to 'forward' them to IMEA or something?

As you can see, I am a begginner in all of this

However, I do have some background in sensors etc even if it isn't my field, and can follow instructions or leads and learn

Effectively, I have the signals, but cant use them

I have 0.8 and 0.10 on two different SD cards, but am using 0.8 as this has 'Inspect' and at least the heading has been passed to OpenCPN as it's value is displayed in the Dash and the boat position marker rotates as the sense hat does
(so perhaps I could use how heading has been done as a 'template' for the other signals to follow - if I knew where to look)

Thanks for you patience, hopefully

Leigh

Which sensors do you want to display in the dashboard ? Unfortunately the dashboard is a bit limited with the nmea it accepts so you might need to convert the NMEA sentences. - What do they look like in the signalk inspector? 

Plus - it's probably a good idea to update openplotter to 15.1 before starting to work on this, there have been so many changes some things which work on 15.1 probably won't work on the older versions.

The Dashboard Plugin recognizes the following input NMEA sentences:

• DBT - Depth Below Transducer
  
• DPT - Depth of Water
  
• GGA - Global Positioning System Fix Data
  
• GLL - Geographic Position - Latitude/Longitude HDG Heading - Deviation & Variation
  
• HDM - Heading - Magnetic
  
• HDT - Heading - True
  
• MTA - Air Temperature (obsolete)
  
• MDA - Meteorological Composite (obsolete)
  
• MTW - Mean Temperature of Water
  
• VLW - Distance Traveled through Water
  
• MWD - Wind Direction & Speed
  
• MWV - Wind Speed and Angle
  
• RMC - Recommended Minimum Navigation Information
  
• RSA - Rudder Sensor Angle
  
• VHW - Water speed and heading
  
• VTG - Track made good and Ground speed
  
• VWR - Relative Wind Speed and Angle
  
• VWT - True Windspeed and Angle (obsolete)
  
• ZDA -Time & Date - UTC, day, month, year and local time zone
  
• AIVDO - Automatic Information System (AIS) position reports from own vessel
