BTW the major cause for this error is usually a network fault either a dodgy connection or terminator.

Dear Steve,

thanks for the new release. Works like a charm. No issues since the update.

Best,

Gediminas, I am having trouble getting OpenCPN to "see" my recently-purchased TouCAN Marine.

Windows 10 Device Manager shows it under Universal Serial Bus devices as "TouCAN converter" with what I assume is the correct serial number. Properties show it using the winusb.sys device driver, which I cannot change.

I have copied the RusokuToucanMarine_v_0_1.dll from the Github repository to the twocan_plugin_pi/data/drivers directory as instructed.

OpenCPN (v. 5.2.4+6b314e6) does NOT show TouCAN Marine as an option in the twocan interfaces list in the plugin Preferences/Settings tab, and if I go to the Device tab, no information about the TouCAN device is shown.

I feel like I am missing something but I cannot figure out what it is. Any recommendations?

Thanks,
Tony

Can you please check the contents of the following directory, assuming the Windows installation and the users home directory location is drive c:

C:\Users\<your username>\AppData\Local\opencpn\plugins\twocan_plugin_pi\data\drivers

Also please check the contents of opencpn.log (normally found in c:\programdata\opencpn).

Whenever you open the twocan preferences dialog, the following is logged to the opencpn log file

Note that the current version of the plugin, version 2.0 installs that updated version of the Toucan Marine driver.

Thanks.

Thanks for your quick reply, stevead.

Here is the contents of the twocan_plugin_pi/data/drivers directory:

The logfile seems to indicate an error loading the driver and an initialization error with the device. Here are what I believe are the relevant lines:

Something doesn't seem right.

08/28/2021  02:53 PM 125,701 RusokuToucanMarine_v_0_1.dll

file size is much too large.

The file size on my install and on the twocan git repository is only around 15k.

Either reinstall the plugin, or download the rusoku driver directly from https://github.com/TwoCanPlugIn/TwoCanPlugIn under the data/drivers directory or from the Rusoku git repository at https://github.com/rusoku/TwoCanRusokuDriver/ from the Prebuilt directory.

[amocjr]

Success!

I reinstalled the dll from github. The previous download must have gotten corrupted or something.

OpenCPN is now seeing the device on my little test NMEA 2K network at home and accepting input from it!

Thanks!

Cheers,
Tony

Hi,

Toucan Marine driver file size is too large.
Where did you get this file ?
Driver size should be ~15kB


Gediminas

[amocjr]

Thank you, Gediminas. Stevead pointed that out as well, so I redownloaded it from the github repository and all is working as expected.

I had previously downloaded the dll from the github repository, but I suspect I made a mistake (something like save link instead of save file).

The only odd thing is that the dll comes with the installation of TwoCAN v. 2.0, but it did not work right after I installed the plugin, either.

No matter, it is working now. The TouCAN Marine is a nice device, I am quite happy with it.

Thanks!
Tony

Hi,
I checked latest version of the OpenCPN 5.2.4+6b3124e6 and TwoCan Plugin 2.0.0.0.
TouCAN Marine works for me with preinstaled driver from TwoCan Plugin package.
Just after selection "TouCAN Marine" item need to reload OpenCPN sofware.


Bad thing that I didn't installed any indicators outside enclosure.Only inside.
Next version will has a lots of light and much more profesional looking milled IP68 enclosure.And 2x CAN FD interfaces and High Speed USB 480Mbit of course.

Does each multiplexer have a differen format? is that why there is a list of hardware to choose from?

Opencpn receives nema2k data from my multiplexer ok but its not in the list so I assume it will not work with the pulgin?
I cant get twocan to show anyguages, let alone data..

[stevead]

Does each multiplexer have a different format?

There is no such thing as a multiplexer on NMEA 2000 networks. NMEA 183 is based on serial ASCII communications with a single talker and multiple listener architecture. Multiplexers are used to combine multiple talkers for NMEA 183 devices, so for example you can connect your depth sounder, speed log and wind sensor to your PC.
NMEA 2000 is very different. It is based on the Controller Area Network (CAN) and it inherently supports multiple talkers & listeners.

Opencpn receives nema2k data from my multiplexer

I' think you are confusing a multiplexer and a gateway. I'm guessing you have a Gateway installed as OpenCPN only natively supports NMEA 183 and SignalK. A Gateway converts NMEA 2000 to NMEA 183.

I cant get twocan to show any guages, let alone data

TwoCan does not display any gauges.

is that why there is a list of hardware to choose from

No the list of interfaces is simply the list of CAN bus adapters and log file formats that the plugin supports. Refer to the wiki for further details on the supported adapters & log file formats. https://opencpn.org/OpenCPN/plugins/twocan.html

I have a multiplexer. It multiplexs nmea 2k in and out, nmea 0183 in and out, seatalk in and out and gps and ais data.

After mulitplexing all that into a nmea data stream of configurable flavor, it creates an ad hoc wifi hot spot - i guess you would call it - which you log into with any device.

all inputs are available at all outputs and over wifi and usb.

OpenCPN only natively supports NMEA 183 and SignalK.

ah ha. news flaash. So I guess the default output is nmea 0183 then. It is soft configurable to nmea 2k and baud rates are also soft configurable.

I am guessing the manfr are fans, cos it comes ready to play with opencpn.

Ah. ok. There was a time when I knew what CAn bus was but then I went sailing...

Can twocan display data in Opencpn?

I hope this is a good link from rpi facebook group. A new can board.

[rgleason]

Al Thomason (Smart Alternator Regulator Group) (and Wakespeed) suggested that he uses this one, but thought there might be better ones, however he found this robust and somewhat expensive.

https://copperhilltech.com/pican-2-c...-raspberry-pi/
He expressed some concern about USB due to grounding and feels Canbus is more stable and prefers that.

I think that DashT and Twocan are made for each other
