mshulman - Does anyone have a CAN to USB device...
Does anyone have a CAN to USB device that they like with good linux drivers? I thought I had one, but I can't build the ubuntu drivers for it.

An implementation of a Signal K central server for boats. - SignalK/signalk-server
lots of options. None of which should require building drivers.
What do you have?

I am using an Intel micro PC running Ubuntu
No idea if that would even work with Signal K
I have a couple of the canable ones. They work fine. I’ve only tried on a pi.
Are you saying that Intel micro PC with Ubuntu won't run signalK, or that the CAN to USB adapter won't work?
The adaptor. I don’t know if it will work.
Hi everyo, i just connect canable pro to the raspi and it doesn't recognize any device. Any suggestions? Thank you!
I think you have to change the firmware
(I know I did, it that was years ago)

Yeah, is it working! But I'm a little confused. Please, help me.
Signal k discovered my Vulcan 7. But it appears NMEA0183 instead of NMEA2000. WHY?
What I want is send wind data from my ST40 which I'm already reading in Openplotter.

The server can discover some tcp 0183 sources
You should ignore that if you have an nmea20000 connection
It does not automatically discover a Canable. You have to add a Data Connection for that.
Here what kind of data do I need to put? Nmea2000 or signalk?


Here should appear raspberry? Because I'm emitting to nmea2000 through canable



I'm very confused 😕
I don’t know what that screenshot is from?
It does not look like you are getting any data from the canable?
What I want is output data to the B&G Vulcan 7 which has NMEA2000 input.
Thank you Scott 🙏
You should be seeing something in the data browser from your n2k network?
Can you screenshot the data connection settings for the canable?
did you run this command
ip link set can0 up type can bitrate 500000
?No, I didn't
it has to be run everytime the pi boots up
Might be that's the problem
I'm not at the boat right now. I'll try tomorrow evening
So, once I'll run that command. I need to do any extra config for output data? I activated wind and other checks at signalk-n2k plugin.
you should not
Ok thank you so much Scott!
but something is off here. I just saw that screeenshot of the candump.
and it looks like you are gertting data
Yes
But might be is corrupted because of the bitrate
might be. I'm not sure what would happen if the butrate is wrong
when you get on the boat, try this after setting the bitrate
Ok
I'll do it
@Scott Bender are you there?
The B&G Vulcan 7 doesnt detect the openplotter data... I'm using Canable Pro 1.0 might be it's broken or the NMEA2000 port from Vulcan 7 is broken. I don't know... I'm going to buy RS485 Can Hat para Raspberry Pi to try other option. Also I'm going to talk another friend to try another plotter.
At the begining I connected just H and L as the manual says. I tried to connect GND because it suggest some devices might need it. But I doesn't work...
this is the log

This is a video with the config
can you try the canboatjs command I gave you?
This one?
I did
You ran candump, not candumpjs
Ohh
You are right
I leave the boat already 🥺
I bought CAN HAT with MCP2515 and it didnt work either 😦

I tried candumpjs can0 and there is no traffic
also I changed the bitrate to can0

candumpjs canable0 (USB slcand device) show the data coming from s2k-nmea2000 plugin but there is no traffic from Vulcan7 to the openplotter.
also I don't know why candumpjs can0 (which correspond to MCP2515 device) doesn't show the data from the plugin sk-nmea2000
The only thing left to try is going to another boat and try another nmea2000 device.
I have a question, I'm connecting directly canbus (H and L) to the plotter Vulcan 7 (B&G). I'm not connecting power and ground. Might be that is the problem? The network nmea2000 is supposed to be powered by 12v?
something like that

I think the Vulcan may require power there
And you need termination
The canable also requires power and ground
Oh. Maybe power, depends on the model
https://canable.io/getting-started.html#connect-to-the-bus

I bought that
I connected everything and it doesn't work 😦


It receives some data at Rx messages

I connected can_l can_h and gnd to the nmea network
And the network is connected to 12v

I connected canable to windows and check if received any data from Vulcan and it doesn't.
All TX errors are definitely suspect
Do you get those when the canable is disconnected?
I'm going to spend more money and time than buying all the devices new 😂😂😂
No
Sorry yes, the Rx changes if I connect the canable.
But the tx are stucked. Even if I reset the counter it goes to 255 automatically and keep there
So hard to tell what’s going on with only two n2k devices.
I'm running out of options to try
The Vulcan or the canable could be bad. Or the wiring could be bad.
I'm going to do a fresh install and use the hat mcp2515 and try with it
Because I don't know why with mcp2515 didn't appear the traces on the console from signal k plugin
Thank you Scott for your help 🙂
Do you really need to do a new install?
No
It's to discard possible errors
If you can borrow another n2k device, that would help a lot. Can be just about anything. That way you could confirm that the Vulcan can see other devices.
Ok I'll try
Thank you
