Query: N2K on Raspberry Pi

[bdbcat]

Hi folks....
We are working in the background on some basic N2K support for OpenCPN core. There are lots of issues, but here is one where we need some specific user feedback.


For those using any sort of N2K interface on Raspberry Pi, or other linux systems:
What is your hardware configuration? How are YOU interfacing your OCPN device to the N2K bus. Detail is useful....


Thanks
Dave

have you looked at the TwoCAN plug-in?

[bradfordharley]

We currently have an actisense N2k to USB adapter on a pi4. We pull it all into signalk and signalk to OpenCPN. I just got a pican2 that I'm about to swap in and if you need any testing, let me know.

I don't use a pi, but the N2K support is very welcome news

• PICAN Dual CAN Bus HAT https://copperhilltech.com/raspberry...l-can-bus-hat/
• signalk doing the translation and prioritization to NMEA0183 => TCP and UDP to several clients, including O

I am using a Can Hat from Waveshare on a Raspberry Pi 4 with TwoCan Plugin or alternatively SignalK connection. Data read are boat sensors (position, COG, SOG, STW, heading, depth, wind), engine data (temp & RPM) displayed via Dashboard or EngineDashBoard and most importantly AIS data.

being able to select sources, i.e. for position, is standard for MFDs. So far I am missing that ability in TwoCan Plugin. My N2K network has two GPS sensors, one is from an AIS transponder which is mounted midships, while the other sensor is mounted on the stern rail. Not being able to select the source for position/SOG/COG, etc makes the position of the boat jump back and forth. Using signalk allows me to avoid that.

How is the support for n2K gateways YachtDevice and Actisense NGT-1?
Would like support for YachtDevices NMEA 2000 USB Gateway YDNU-02

We are not yet ready to announce specific features of the n2k work. So I would rather not get into details of the feature yet.
This thread is only to query what user are doing today, if anything, with n2k. There will be more discussion later as the picture clears.



Teaser: the YDNU-02 is on the proposed list of supported devices.

Hi Dave,

i'am using NMEA2000 on Linux systems and on my Raspberry Pi 4.

I think you need an canbus adapter any way.

I'am using an Adaptec NGT-1 which is not cheap and also the Canable with the Candlelight firmware. Is cheap but not available at the moment.

There is Chinees version called Canable MK which cost $ 24,-. Works just as well.
Tested here for some time.

Both use in- and output to the NMEA2000 network.

All the data is processed with the SignalK server.

OpenCPN route data can also be send to the SignalK server. And with the right settings the OpenCPN route data appears on the NMEA2000 B&G instruments display sets.

This setup works very well.

I think the separate SignalK data server is a great idea. With only two connection to OpenCPN.: SignalK data in and NMEA183 route data route out to the SK server.

Regards,


Bram

The Canable MK board image. Only the white and blue wires ar connected tyo the board.

Dave, my setup is:
- RPi4 using running Signal K and connected to a USBtin CAN-converter using slcan.
- Signal K generates NMEA 0183, this is required for some equipment, so I use it for all.
- Sending NMEA 0183 over internet (2-point) to a standard PC (CAR-PC) with Ubundu 20.04 running OpenCPN.

Crossing my fingers it will support wifi adapters as well. The YDWG-2 and actisence w2k-1 both support nmea2000 over wifi.

N2K input: NGT-1 -> Signalk -> OpenCPN, running Core-i5/Ubuntu
N2K Output: YDWG-02

Separating N2K Input/Output(autopilot) to better/easier handle signalpaths/filtering/loops.

All inputs to OpenCPN except $TALK(<->YDWG-02), from SignalK.
